-## Usage
-
-```sh
-pip install playwright
-python -m playwright install
-```
-
-This installs Playwright and browser binaries for Chromium, Firefox and WebKit. Playwright requires Python 3.7+.

-#### Record and generate code
+## Documentation
 
-Playwright can record user interactions in a browser and generate code. [See demo](https://user-images.githubusercontent.com/284612/95930164-ad52fb80-0d7a-11eb-852d-04bfd19de800.gif).
+[https://playwright.dev/python/docs/intro](https://playwright.dev/python/docs/intro)
 
-```sh
-# Pass --help to see all options
-python -m playwright codegen
-```
+## API Reference
 
-Playwright offers both sync (blocking) API and async API. They are identical in terms of capabilities and only differ in how one consumes the API.
+[https://playwright.dev/python/docs/api/class-playwright](https://playwright.dev/python/docs/api/class-playwright)
 
-#### Sync API
+## Example
 
 ```py
-from playwright import sync_playwright
+from playwright.sync_api import sync_playwright
 
 with sync_playwright() as p:
     for browser_type in [p.chromium, p.firefox, p.webkit]:
         browser = browser_type.launch()
-        page = browser.newPage()
-        page.goto('http://whatsmyuseragent.org/')
+        page = browser.new_page()
+        page.goto('http://playwright.dev')
         page.screenshot(path=f'example-{browser_type.name}.png')
         browser.close()
 ```
 
-#### Async API
-
 ```py
 import asyncio
-from playwright import async_playwright
+from playwright.async_api import async_playwright
 
 async def main():
     async with async_playwright() as p:
         for browser_type in [p.chromium, p.firefox, p.webkit]:
             browser = await browser_type.launch()
-            page = await browser.newPage()
-            await page.goto('http://whatsmyuseragent.org/')
+            page = await browser.new_page()
+            await page.goto('http://playwright.dev')
             await page.screenshot(path=f'example-{browser_type.name}.png')
             await browser.close()
 
-asyncio.get_event_loop().run_until_complete(main())
-```
-
-#### With pytest
-
-Use our [pytest plugin for Playwright](https://github.com/microsoft/playwright-pytest#readme).
-
-```py
-def test_playwright_is_visible_on_google(page):
-    page.goto("https://www.google.com")
-    page.type("input[name=q]", "Playwright GitHub")
-    page.click("input[type=submit]")
-    page.waitForSelector("text=microsoft/Playwright")
-```
-
-#### Interactive mode (REPL)
-
-```py
->>> from playwright import sync_playwright
->>> playwright = sync_playwright().start()
-
-# Use playwright.chromium, playwright.firefox or playwright.webkit
-# Pass headless=False to see the browser UI
->>> browser = playwright.chromium.launch()
->>> page = browser.newPage()
->>> page.goto("http://whatsmyuseragent.org/")
->>> page.screenshot(path="example.png")
->>> browser.close()
->>> playwright.stop()
-```
-
-## Examples
-
-#### Mobile and geolocation
-
-This snippet emulates Mobile Safari on a device at a given geolocation, navigates to maps.google.com, performs action and takes a screenshot.
-
-```py
-from playwright import sync_playwright
-
-with sync_playwright() as p:

-## Documentation
-
-We are in the process of converting our [documentation](https://playwright.dev/) from the Node.js form to Python. You can go ahead and use the Node.js documentation since the API is pretty much the same. Playwright uses non-Python naming conventions (`camelCase` instead of `snake_case`) for its methods. We recognize that this is not ideal, but it was done deliberately, so that you could rely upon Stack Overflow answers and existing documentation.
-
-### Named arguments
-
-Since Python allows named arguments, we didn't need to put the `options` parameter into every call as in the Node.js API. So when you see example like this in JavaScript
-
-```js
-await webkit.launch({ headless: false });
-```
-
-It translates into Python like this:
-
-```py
-webkit.launch(headless=False)
+asyncio.run(main())
 ```
 
-If you are using an IDE, it will suggest parameters that are available in every call.
-
-### Evaluating functions
-
-Another difference is that in the JavaScript version, `page.evaluate` accepts JavaScript functions, while this does not make any sense in the Python version.
-
-In JavaScript it will be documented as:
-
-```js
-const result = await page.evaluate(([x, y]) => {
-  return Promise.resolve(x * y);
-}, [7, 8]);
-console.log(result); // prints "56"
-```
-
-And in Python that would look like:
-
-```py
-result = page.evaluate("""
-    ([x, y]) => {
-        return Promise.resolve(x * y);
-    }""",
-    [7, 8])
-print(result) # prints "56"
-```
-
-The library will detect that what are passing it is a function and will invoke it with the given parameters. You can opt out of this function detection and pass `force_expr=True` to all evaluate functions, but you probably will never need to do that.
-
-### Using context managers
-
-Python enabled us to do some of the things that were not possible in the Node.js version and we used the opportunity. Instead of using the `page.waitFor*` methods, we recommend using corresponding `page.expect_*` context manager.
-
-In JavaScript it will be documented as:
-
-```js
-const [ download ] = await Promise.all([
-  page.waitForEvent('download'), // <-- start waiting for the download
-  page.click('button#delayed-download') // <-- perform the action that directly or indirectly initiates it.
-]);
-const path = await download.path();
-```
-
-And in Python that would look much simpler:
-
-```py
-with page.expect_download() as download_info:
-    page.click("button#delayed-download")
-download = download_info.value
-path = download.path()
-```
-
-Similarly, for waiting for the network response:
-
-```js
-const [response] = await Promise.all([
-  page.waitForResponse('**/api/fetch_data'),
-  page.click('button#update'),
-]);
-```
-
-Becomes
-
-```py
-with page.expect_response("**/api/fetch_data"):
-    page.click("button#update")
-```
-
-## Is Playwright for Python ready?
-
-Yes, Playwright for Python is ready. We are still not at the version v1.0, so minor breaking API changes could potentially happen. But a) this is unlikely and b) we will only do that if we know it improves your experience with the new library. We'd like to collect your feedback before we freeze the API for v1.0.
+## Other languages
 
-> Note: We don't yet support some of the edge-cases of the vendor-specific APIs such as collecting Chromium trace, coverage report, etc.
+More comfortable in another programming language? [Playwright](https://playwright.dev) is also available in
+- [Node.js (JavaScript / TypeScript)](https://playwright.dev/docs/intro),
+- [.NET](https://playwright.dev/dotnet/docs/intro),
+- [Java](https://playwright.dev/java/docs/intro).

+
+        Continues route's request with optional overrides. The method is similar to `route.continue_()` with the
+        difference that other matching handlers will be invoked before sending the request.
+
+        **Usage**
+
+        When several routes match the given pattern, they run in the order opposite to their registration. That way the
+        last registered route can always override all the previous ones. In the example below, request will be handled by
+        the bottom-most handler first, then it'll fall back to the previous one and in the end will be aborted by the first
+        registered route.
+
+        ```py
+        await page.route(\"**/*\", lambda route: route.abort())  # Runs last.
+        await page.route(\"**/*\", lambda route: route.fallback())  # Runs second.
+        await page.route(\"**/*\", lambda route: route.fallback())  # Runs first.
+        ```
 
-mapping.register(RouteImpl, Route)
+        Registering multiple routes is useful when you want separate handlers to handle different kinds of requests, for
+        example API calls vs page resources or GET requests vs POST requests as in the example below.
+
+        ```py
+        # Handle GET requests.
+        async def handle_get(route):
+            if route.request.method != \"GET\":
+                await route.fallback()
+                return
+          # Handling GET only.
+          # ...
+
+        # Handle POST requests.
+        async def handle_post(route):
+            if route.request.method != \"POST\":
+                await route.fallback()
+                return
+          # Handling POST only.
+          # ...
+
+        await page.route(\"**/*\", handle_get)
+        await page.route(\"**/*\", handle_post)
+        ```
 
+        One can also modify request while falling back to the subsequent handler, that way intermediate route handler can
+        modify url, method, headers and postData of the request.

             The quality of the image, between 0-100. Not applicable to `png` images.
-        omit_background : Union[bool, NoneType]
+        omit_background : Union[bool, None]
             Hides default white background and allows capturing screenshots with transparency. Not applicable to `jpeg` images.
             Defaults to `false`.
+        animations : Union["allow", "disabled", None]
+            When set to `"disabled"`, stops CSS animations, CSS transitions and Web Animations. Animations get different
+            treatment depending on their duration:
+            - finite animations are fast-forwarded to completion, so they'll fire `transitionend` event.
+            - infinite animations are canceled to initial state, and then played over after the screenshot.
+
+            Defaults to `"allow"` that leaves animations untouched.
+        caret : Union["hide", "initial", None]
+            When set to `"hide"`, screenshot will hide text caret. When set to `"initial"`, text caret behavior will not be
+            changed.  Defaults to `"hide"`.
+        scale : Union["css", "device", None]
+            When set to `"css"`, screenshot will have a single pixel per each css pixel on the page. For high-dpi devices, this
+            will keep screenshots small. Using `"device"` option will produce a single pixel per each device pixel, so
+            screenshots of high-dpi devices will be twice as large or even larger.
+
+            Defaults to `"device"`.
+        mask : Union[Sequence[Locator], None]
+            Specify locators that should be masked when the screenshot is taken. Masked elements will be overlaid with a pink
+            box `#FF00FF` (customized by `maskColor`) that completely covers its bounding box. The mask is also applied to
+            invisible elements, see [Matching only visible elements](../locators.md#matching-only-visible-elements) to disable
+            that.
+        mask_color : Union[str, None]
+            Specify the color of the overlay box for masked elements, in
+            [CSS color format](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value). Default color is pink `#FF00FF`.
+        style : Union[str, None]
+            Text of the stylesheet to apply while making the screenshot. This is where you can hide dynamic elements, make
+            elements invisible or change their properties to help you creating repeatable screenshots. This stylesheet pierces
+            the Shadow DOM and applies to the inner frames.

         Parameters
         ----------
         selector : str
-            A selector to query for. See [working with selectors](./selectors.md#working-with-selectors) for more details.
-        state : Union["attached", "detached", "hidden", "visible", NoneType]
+            A selector to query for.
+        state : Union["attached", "detached", "hidden", "visible", None]
             Defaults to `'visible'`. Can be either:
             - `'attached'` - wait for element to be present in DOM.
             - `'detached'` - wait for element to not be present in DOM.
-            - `'visible'` - wait for element to have non-empty bounding box and no `visibility:hidden`. Note that element without
-              any content or with `display:none` has an empty bounding box and is not considered visible.
-            - `'hidden'` - wait for element to be either detached from DOM, or have an empty bounding box or `visibility:hidden`.
-              This is opposite to the `'visible'` option.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+            - `'visible'` - wait for element to have non-empty bounding box and no `visibility:hidden`. Note that element
+              without any content or with `display:none` has an empty bounding box and is not considered visible.
+            - `'hidden'` - wait for element to be either detached from DOM, or have an empty bounding box or
+              `visibility:hidden`. This is opposite to the `'visible'` option.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        strict : Union[bool, None]
+            When true, the call requires selector to resolve to a single element. If given selector resolves to more than one
+            element, the call throws an exception.

         Parameters
         ----------
         selector : str
-            A selector to query for. See [working with selectors](./selectors.md#working-with-selectors) for more details.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
-        state : Union["attached", "detached", "hidden", "visible", NoneType]
+            A selector to query for.
+        strict : Union[bool, None]

+        state : Union["attached", "detached", "hidden", "visible", None]
             Defaults to `'visible'`. Can be either:
             - `'attached'` - wait for element to be present in DOM.
             - `'detached'` - wait for element to not be present in DOM.
-            - `'visible'` - wait for element to have non-empty bounding box and no `visibility:hidden`. Note that element without
-              any content or with `display:none` has an empty bounding box and is not considered visible.
-            - `'hidden'` - wait for element to be either detached from DOM, or have an empty bounding box or `visibility:hidden`.
-              This is opposite to the `'visible'` option.

         Parameters
         ----------
         selector : str
-            A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See
-            [working with selectors](./selectors.md#working-with-selectors) for more details.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+            A selector to use when resolving DOM element.
+        has_text : Union[Pattern[str], str, None]
+            Matches elements containing specified text somewhere inside, possibly in a child or a descendant element. When
+            passed a [string], matching is case-insensitive and searches for a substring. For example, `"Playwright"` matches
+            `<article><div>Playwright</div></article>`.
+        has_not_text : Union[Pattern[str], str, None]
+            Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element.
+            When passed a [string], matching is case-insensitive and searches for a substring.
+        has : Union[Locator, None]
+            Narrows down the results of the method to those which contain elements matching this relative locator. For example,
+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in
+            `<article><content><div>Playwright</div></content></article>`. However, looking for `content` that has `article
+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the
+            outer one. For example, `article` that does not have `div` matches `<article><span>Playwright</span></article>`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.

+
+        **Usage**
+

+
+        Role selector **does not replace** accessibility audits and conformance tests, but rather gives early feedback
+        about the ARIA guidelines.
+
+        Many html elements have an implicitly [defined role](https://w3c.github.io/html-aam/#html-element-role-mappings)
+        that is recognized by the role selector. You can find all the
+        [supported roles here](https://www.w3.org/TR/wai-aria-1.2/#role_definitions). ARIA guidelines **do not recommend**
+        duplicating implicit roles and attributes by setting `role` and/or `aria-*` attributes to default values.

+            Required aria role.
+        checked : Union[bool, None]
+            An attribute that is usually set by `aria-checked` or native `<input type=checkbox>` controls.
+
+            Learn more about [`aria-checked`](https://www.w3.org/TR/wai-aria-1.2/#aria-checked).
+        disabled : Union[bool, None]
+            An attribute that is usually set by `aria-disabled` or `disabled`.
+
+            **NOTE** Unlike most other attributes, `disabled` is inherited through the DOM hierarchy. Learn more about
+            [`aria-disabled`](https://www.w3.org/TR/wai-aria-1.2/#aria-disabled).
+
+        expanded : Union[bool, None]
+            An attribute that is usually set by `aria-expanded`.
+
+            Learn more about [`aria-expanded`](https://www.w3.org/TR/wai-aria-1.2/#aria-expanded).
+        include_hidden : Union[bool, None]
+            Option that controls whether hidden elements are matched. By default, only non-hidden elements, as
+            [defined by ARIA](https://www.w3.org/TR/wai-aria-1.2/#tree_exclusion), are matched by role selector.
+
+            Learn more about [`aria-hidden`](https://www.w3.org/TR/wai-aria-1.2/#aria-hidden).
+        level : Union[int, None]
+            A number attribute that is usually present for roles `heading`, `listitem`, `row`, `treeitem`, with default values
+            for `<h1>-<h6>` elements.
+
+            Learn more about [`aria-level`](https://www.w3.org/TR/wai-aria-1.2/#aria-level).
+        name : Union[Pattern[str], str, None]
+            Option to match the [accessible name](https://w3c.github.io/accname/#dfn-accessible-name). By default, matching is
+            case-insensitive and searches for a substring, use `exact` to control this behavior.
+
+            Learn more about [accessible name](https://w3c.github.io/accname/#dfn-accessible-name).
+        pressed : Union[bool, None]

+        ```
+
+        **Details**
+
+        Matching by text always normalizes whitespace, even with exact match. For example, it turns multiple spaces into
+        one, turns line breaks into spaces and ignores leading and trailing whitespace.
+
+        Input elements of the type `button` and `submit` are matched by their `value` instead of the text content. For

         ----------
         selector : str
-            A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See

-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
-        force : Union[bool, NoneType]
-            Whether to bypass the [actionability](./actionability.md) checks. Defaults to `false`.
-        no_wait_after : Union[bool, NoneType]
-            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can
-            opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as navigating to

+        **Usage**
+
+        The `frame.wait_for_function()` can be used to observe viewport size change:
+
+        ```py
+        import asyncio
+        from playwright.async_api import async_playwright, Playwright
+
+        async def run(playwright: Playwright):

+            await page.evaluate(\"window.x = 0; setTimeout(() => { window.x = 100 }, 1000);\")
+            await page.main_frame.wait_for_function(\"() => window.x > 0\")
+            await browser.close()
 
-        The `waitForFunction` can be used to observe viewport size change:

         Parameters
         ----------
-        expression : str
-            Function to be evaluated in the page context
-        force_expr : bool
-            Whether to treat given expression as JavaScript evaluate expression, even though it looks like an arrow function
-        arg : Union[Any, NoneType]
-            Optional argument to pass to `pageFunction`
+        selector_or_locator : Union[Locator, str]
+            A selector or locator to use when resolving DOM element.
+        has_text : Union[Pattern[str], str, None]
+            Matches elements containing specified text somewhere inside, possibly in a child or a descendant element. When
+            passed a [string], matching is case-insensitive and searches for a substring. For example, `"Playwright"` matches
+            `<article><div>Playwright</div></article>`.
+        has_not_text : Union[Pattern[str], str, None]
+            Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element.
+            When passed a [string], matching is case-insensitive and searches for a substring.
+        has : Union[Locator, None]
+            Narrows down the results of the method to those which contain elements matching this relative locator. For example,
+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in
+            `<article><content><div>Playwright</div></content></article>`. However, looking for `content` that has `article
+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the
+            outer one. For example, `article` that does not have `div` matches `<article><span>Playwright</span></article>`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.

+        Role selector **does not replace** accessibility audits and conformance tests, but rather gives early feedback
+        about the ARIA guidelines.
+
+        Many html elements have an implicitly [defined role](https://w3c.github.io/html-aam/#html-element-role-mappings)
+        that is recognized by the role selector. You can find all the
+        [supported roles here](https://www.w3.org/TR/wai-aria-1.2/#role_definitions). ARIA guidelines **do not recommend**
+        duplicating implicit roles and attributes by setting `role` and/or `aria-*` attributes to default values.

-        state : Union["attached", "detached", "hidden", "visible", NoneType]
-            Defaults to `'visible'`. Can be either:
-            - `'attached'` - wait for element to be present in DOM.
-            - `'detached'` - wait for element to not be present in DOM.
-            - `'visible'` - wait for element to have non-empty bounding box and no `visibility:hidden`. Note that element without
-              any content or with `display:none` has an empty bounding box and is not considered visible.
-            - `'hidden'` - wait for element to be either detached from DOM, or have an empty bounding box or `visibility:hidden`.

+        **Usage**
 
-        You can also specify `JSHandle` as the property value if you want live objects to be passed into the event:
+        ```py
+        await page.clock.pause_at(datetime.datetime(2020, 2, 2))
+        await page.clock.pause_at(\"2020-02-02\")
+        ```
+
+        For best results, install the clock before navigating the page and set it to a time slightly before the intended
+        test time. This ensures that all timers run normally during page loading, preventing the page from getting stuck.
+        Once the page has fully loaded, you can safely use `clock.pause_at()` to pause the clock.
+
+        ```py
+        # Initialize clock with some time before the test time and let the page load
+        # naturally. `Date.now` will progress as the timers fire.
+        await page.clock.install(time=datetime.datetime(2024, 12, 10, 8, 0, 0))
+        await page.goto(\"http://localhost:3333\")
+        await page.clock.pause_at(datetime.datetime(2024, 12, 10, 10, 0, 0))
+        ```
 
         Parameters
         ----------
-        selector : str
-            A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See
-            [working with selectors](./selectors.md#working-with-selectors) for more details.
-        type : str
-            DOM event type: `"click"`, `"dragstart"`, etc.
-        event_init : Union[Dict, NoneType]
-            Optional event-specific initialization properties.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        time : Union[datetime.datetime, float, str]
+            Time to pause at.

+mapping.register(DownloadImpl, Download)
 
-        Parameters
-        ----------
-        url : Union[Callable[[str], bool], Pattern, str, NoneType]
-            A glob pattern, regex pattern or predicate receiving [URL] to match while waiting for the navigation.
-        wait_until : Union["domcontentloaded", "load", "networkidle", NoneType]
-            When to consider operation succeeded, defaults to `load`. Events can be either:
-            - `'domcontentloaded'` - consider operation to be finished when the `DOMContentLoaded` event is fired.
-            - `'load'` - consider operation to be finished when the `load` event is fired.
-            - `'networkidle'` - consider operation to be finished when there are no network connections for at least `500` ms.
-        timeout : Union[float, NoneType]
-            Maximum operation time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be
-            changed by using the `browser_context.set_default_navigation_timeout()`,
-            `browser_context.set_default_timeout()`, `page.set_default_navigation_timeout()` or
-            `page.set_default_timeout()` methods.

+        aborted.
+
+        **NOTE** The handler will only be called for the first url if the response is a redirect.
+
+        **NOTE** `page.route()` will not intercept requests intercepted by Service Worker. See
+        [this](https://github.com/microsoft/playwright/issues/1090) issue. We recommend disabling Service Workers when
+        using request interception by setting `serviceWorkers` to `'block'`.
+
+        **NOTE** `page.route()` will not intercept the first request of a popup page. Use
+        `browser_context.route()` instead.
+
+        **Usage**
+
+        An example of a naive handler that aborts all image requests:
+
+        ```py
+        page = await browser.new_page()
+        await page.route(\"**/*.{png,jpg,jpeg}\", lambda route: route.abort())

+        await page.route(re.compile(r\"(\\.png$)|(\\.jpg$)\"), lambda route: route.abort())
+        await page.goto(\"https://example.com\")
+        await browser.close()
+        ```
+
+        It is possible to examine the request to decide the route action. For example, mocking all requests that contain
+        some post data, and leaving all other requests as is:
+
+        ```py
+        async def handle_route(route: Route):

+        await page.route(\"/api/**\", handle_route)
+        ```
+
+        Page routes take precedence over browser context routes (set up with `browser_context.route()`) when request
+        matches both handlers.
+
+        To remove a route with its handler you can use `page.unroute()`.

+        type : Union["jpeg", "png", None]
+            Specify screenshot type, defaults to `png`.
+        path : Union[pathlib.Path, str, None]
+            The file path to save the image to. The screenshot type will be inferred from file extension. If `path` is a
+            relative path, then it is resolved relative to the current working directory. If no path is provided, the image
+            won't be saved to the disk.
+        quality : Union[int, None]
+            The quality of the image, between 0-100. Not applicable to `png` images.
+        omit_background : Union[bool, None]
+            Hides default white background and allows capturing screenshots with transparency. Not applicable to `jpeg` images.
+            Defaults to `false`.
+        full_page : Union[bool, None]
+            When true, takes a screenshot of the full scrollable page, instead of the currently visible viewport. Defaults to
+            `false`.
+        clip : Union[{x: float, y: float, width: float, height: float}, None]
+            An object which specifies clipping of the resulting image.
+        animations : Union["allow", "disabled", None]
+            When set to `"disabled"`, stops CSS animations, CSS transitions and Web Animations. Animations get different
+            treatment depending on their duration:
+            - finite animations are fast-forwarded to completion, so they'll fire `transitionend` event.
+            - infinite animations are canceled to initial state, and then played over after the screenshot.
+
+            Defaults to `"allow"` that leaves animations untouched.
+        caret : Union["hide", "initial", None]
+            When set to `"hide"`, screenshot will hide text caret. When set to `"initial"`, text caret behavior will not be
+            changed.  Defaults to `"hide"`.
+        scale : Union["css", "device", None]
+            When set to `"css"`, screenshot will have a single pixel per each css pixel on the page. For high-dpi devices, this
+            will keep screenshots small. Using `"device"` option will produce a single pixel per each device pixel, so
+            screenshots of high-dpi devices will be twice as large or even larger.
+
+            Defaults to `"device"`.
+        mask : Union[Sequence[Locator], None]
+            Specify locators that should be masked when the screenshot is taken. Masked elements will be overlaid with a pink
+            box `#FF00FF` (customized by `maskColor`) that completely covers its bounding box. The mask is also applied to
+            invisible elements, see [Matching only visible elements](../locators.md#matching-only-visible-elements) to disable
+            that.
+        mask_color : Union[str, None]
+            Specify the color of the overlay box for masked elements, in
+            [CSS color format](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value). Default color is pink `#FF00FF`.
+        style : Union[str, None]
+            Text of the stylesheet to apply while making the screenshot. This is where you can hide dynamic elements, make
+            elements invisible or change their properties to help you creating repeatable screenshots. This stylesheet pierces
+            the Shadow DOM and applies to the inner frames.

+        position : Union[{x: float, y: float}, None]
+            A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of
+            the element.
+        delay : Union[float, None]
+            Time to wait between `mousedown` and `mouseup` in milliseconds. Defaults to 0.

+        click_count : Union[int, None]

+        This method double clicks an element matching `selector` by performing the following steps:

+        1. Wait for [actionability](https://playwright.dev/python/docs/actionability) checks on the matched element, unless `force` option is set. If

+            A selector to search for an element. If there are multiple elements satisfying the selector, the first will be
+            used.
+        modifiers : Union[Sequence[Union["Alt", "Control", "ControlOrMeta", "Meta", "Shift"]], None]
+            Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores
+            current modifiers back. If not specified, currently pressed modifiers are used. "ControlOrMeta" resolves to
+            "Control" on Windows and Linux and to "Meta" on macOS.
+        position : Union[{x: float, y: float}, None]
+            A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of
+            the element.
+        delay : Union[float, None]
+            Time to wait between `mousedown` and `mouseup` in milliseconds. Defaults to 0.
+        button : Union["left", "middle", "right", None]
+            Defaults to `left`.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        force : Union[bool, None]

+            When true, the call requires selector to resolve to a single element. If given selector resolves to more than one

+        trial : Union[bool, None]
+            When set, this method only performs the [actionability](../actionability.md) checks and skips the action. Defaults

+
+        The method returns an element locator that can be used to perform actions on this page / frame. Locator is resolved

+        performed on different DOM elements. That would happen if the DOM structure between those actions has changed.
+
+        [Learn more about locators](https://playwright.dev/python/docs/locators).
+
+        Parameters
+        ----------
+        selector : str
+            A selector to use when resolving DOM element.
+        has_text : Union[Pattern[str], str, None]
+            Matches elements containing specified text somewhere inside, possibly in a child or a descendant element. When
+            passed a [string], matching is case-insensitive and searches for a substring. For example, `"Playwright"` matches
+            `<article><div>Playwright</div></article>`.
+        has_not_text : Union[Pattern[str], str, None]
+            Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element.
+            When passed a [string], matching is case-insensitive and searches for a substring.
+        has : Union[Locator, None]
+            Narrows down the results of the method to those which contain elements matching this relative locator. For example,
+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in
+            `<article><content><div>Playwright</div></content></article>`. However, looking for `content` that has `article
+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the
+            outer one. For example, `article` that does not have `div` matches `<article><span>Playwright</span></article>`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.

+
+        **Usage**
+
+        Consider the following DOM structure.

+
+        Role selector **does not replace** accessibility audits and conformance tests, but rather gives early feedback
+        about the ARIA guidelines.
+
+        Many html elements have an implicitly [defined role](https://w3c.github.io/html-aam/#html-element-role-mappings)
+        that is recognized by the role selector. You can find all the
+        [supported roles here](https://www.w3.org/TR/wai-aria-1.2/#role_definitions). ARIA guidelines **do not recommend**
+        duplicating implicit roles and attributes by setting `role` and/or `aria-*` attributes to default values.

+            Required aria role.
+        checked : Union[bool, None]
+            An attribute that is usually set by `aria-checked` or native `<input type=checkbox>` controls.
+
+            Learn more about [`aria-checked`](https://www.w3.org/TR/wai-aria-1.2/#aria-checked).
+        disabled : Union[bool, None]
+            An attribute that is usually set by `aria-disabled` or `disabled`.
+
+            **NOTE** Unlike most other attributes, `disabled` is inherited through the DOM hierarchy. Learn more about
+            [`aria-disabled`](https://www.w3.org/TR/wai-aria-1.2/#aria-disabled).
+
+        expanded : Union[bool, None]
+            An attribute that is usually set by `aria-expanded`.
+
+            Learn more about [`aria-expanded`](https://www.w3.org/TR/wai-aria-1.2/#aria-expanded).
+        include_hidden : Union[bool, None]
+            Option that controls whether hidden elements are matched. By default, only non-hidden elements, as
+            [defined by ARIA](https://www.w3.org/TR/wai-aria-1.2/#tree_exclusion), are matched by role selector.
+
+            Learn more about [`aria-hidden`](https://www.w3.org/TR/wai-aria-1.2/#aria-hidden).
+        level : Union[int, None]
+            A number attribute that is usually present for roles `heading`, `listitem`, `row`, `treeitem`, with default values
+            for `<h1>-<h6>` elements.
+
+            Learn more about [`aria-level`](https://www.w3.org/TR/wai-aria-1.2/#aria-level).
+        name : Union[Pattern[str], str, None]
+            Option to match the [accessible name](https://w3c.github.io/accname/#dfn-accessible-name). By default, matching is
+            case-insensitive and searches for a substring, use `exact` to control this behavior.
+
+            Learn more about [accessible name](https://w3c.github.io/accname/#dfn-accessible-name).
+        pressed : Union[bool, None]
+            An attribute that is usually set by `aria-pressed`.
+
+            Learn more about [`aria-pressed`](https://www.w3.org/TR/wai-aria-1.2/#aria-pressed).
+        selected : Union[bool, None]

+
+        **Details**
+
+        Matching by text always normalizes whitespace, even with exact match. For example, it turns multiple spaces into
+        one, turns line breaks into spaces and ignores leading and trailing whitespace.
+
+        Input elements of the type `button` and `submit` are matched by their `value` instead of the text content. For

+
+        This method hovers over an element matching `selector` by performing the following steps:
+        1. Find an element matching `selector`. If there is none, wait until a matching element is attached to the DOM.
+        1. Wait for [actionability](https://playwright.dev/python/docs/actionability) checks on the matched element, unless `force` option is set. If
+           the element is detached during the checks, the whole action is retried.
+        1. Scroll the element into view if needed.
+        1. Use `page.mouse` to hover over the center of the element, or the specified `position`.
+
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.
+        Passing zero timeout disables this.
+
+        Parameters
+        ----------
+        selector : str
+            A selector to search for an element. If there are multiple elements satisfying the selector, the first will be
+            used.
+        modifiers : Union[Sequence[Union["Alt", "Control", "ControlOrMeta", "Meta", "Shift"]], None]
+            Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores
+            current modifiers back. If not specified, currently pressed modifiers are used. "ControlOrMeta" resolves to
+            "Control" on Windows and Linux and to "Meta" on macOS.
+        position : Union[{x: float, y: float}, None]
+            A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of
+            the element.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        no_wait_after : Union[bool, None]
+            This option has no effect.
+            Deprecated: This option has no effect.
+        force : Union[bool, None]

+        strict : Union[bool, None]

+        Holding down `Shift` will type the text that corresponds to the `key` in the upper case.
+
+        If `key` is a single character, it is case-sensitive, so the values `a` and `A` will generate different respective
+        texts.
+
+        Shortcuts such as `key: \"Control+o\"`, `key: \"Control++` or `key: \"Control+Shift+T\"` are supported as well. When
+        specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.
+
+        **Usage**
+
+        ```py
+        page = await browser.new_page()
+        await page.goto(\"https://keycode.info\")
+        await page.press(\"body\", \"A\")

+
+        Parameters
+        ----------
+        selector : str
+            A selector to search for an element. If there are multiple elements satisfying the selector, the first will be
+            used.
+        key : str

+        delay : Union[float, None]
+            Time to wait between `keydown` and `keyup` in milliseconds. Defaults to 0.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        no_wait_after : Union[bool, None]
+            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You
+            can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as
+            navigating to inaccessible pages. Defaults to `false`.
+            Deprecated: This option will default to `true` in the future.
+        strict : Union[bool, None]
+            When true, the call requires selector to resolve to a single element. If given selector resolves to more than one

+            Paper height, accepts values labeled with units.
+        prefer_css_page_size : Union[bool, None]
+            Give any CSS `@page` size declared in the page priority over what is declared in `width` and `height` or `format`
+            options. Defaults to `false`, which will scale the content to fit the paper size.
+        margin : Union[{top: Union[float, str, None], right: Union[float, str, None], bottom: Union[float, str, None], left: Union[float, str, None]}, None]

+
+        **Usage**
+
+        This resolves when the page navigates to a new URL or reloads. It is useful for when you run code which will
+        indirectly cause the page to navigate. e.g. The click target has an `onclick` handler that triggers navigation from
+        a `setTimeout`. Consider this example:
+
+        ```py
+        async with page.expect_navigation():
+            # This action triggers the navigation after a timeout.
+            await page.get_by_text(\"Navigate after timeout\").click()
+        # Resolves after navigation has finished
+        ```
+
+        **NOTE** Usage of the [History API](https://developer.mozilla.org/en-US/docs/Web/API/History_API) to change the URL
+        is considered a navigation.

+        Parameters
+        ----------
+        url : Union[Callable[[str], bool], Pattern[str], str, None]
+            A glob pattern, regex pattern or predicate receiving [URL] to match while waiting for the navigation. Note that if
+            the parameter is a string without wildcard characters, the method will wait for navigation to URL that is exactly
+            equal to the string.
+        wait_until : Union["commit", "domcontentloaded", "load", "networkidle", None]
+            When to consider operation succeeded, defaults to `load`. Events can be either:
+            - `'domcontentloaded'` - consider operation to be finished when the `DOMContentLoaded` event is fired.
+            - `'load'` - consider operation to be finished when the `load` event is fired.
+            - `'networkidle'` - **DISCOURAGED** consider operation to be finished when there are no network connections for
+              at least `500` ms. Don't use this method for testing, rely on web assertions to assess readiness instead.
+            - `'commit'` - consider operation to be finished when network response is received and the document started
+              loading.
+        timeout : Union[float, None]

+        1. Find an element matching `selector`. If there is none, wait until a matching element is attached to the DOM.
+        1. Ensure that matched element is a checkbox or a radio input. If not, this method throws.
+        1. If the element already has the right checked state, this method returns immediately.
+        1. Wait for [actionability](https://playwright.dev/python/docs/actionability) checks on the matched element, unless `force` option is set. If
+           the element is detached during the checks, the whole action is retried.
+        1. Scroll the element into view if needed.
+        1. Use `page.mouse` to click in the center of the element.
+        1. Ensure that the element is now checked or unchecked. If not, this method throws.
+
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.
+        Passing zero timeout disables this.
+
+        Parameters
+        ----------
+        selector : str
+            A selector to search for an element. If there are multiple elements satisfying the selector, the first will be
+            used.
+        checked : bool
+            Whether to check or uncheck the checkbox.
+        position : Union[{x: float, y: float}, None]
+            A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of
+            the element.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        force : Union[bool, None]
+            Whether to bypass the [actionability](../actionability.md) checks. Defaults to `false`.
+        no_wait_after : Union[bool, None]
+            This option has no effect.
+            Deprecated: This option has no effect.
+        strict : Union[bool, None]
+            When true, the call requires selector to resolve to a single element. If given selector resolves to more than one
+            element, the call throws an exception.
+        trial : Union[bool, None]
+            When set, this method only performs the [actionability](../actionability.md) checks and skips the action. Defaults
+            to `false`. Useful to wait until the element is ready for the action without performing it.

+
+        When testing a web page, sometimes unexpected overlays like a \"Sign up\" dialog appear and block actions you want to
+        automate, e.g. clicking a button. These overlays don't always show up in the same way or at the same time, making
+        them tricky to handle in automated tests.
+
+        This method lets you set up a special function, called a handler, that activates when it detects that overlay is
+        visible. The handler's job is to remove the overlay, allowing your test to continue as if the overlay wasn't there.
+
+        Things to keep in mind:
+        - When an overlay is shown predictably, we recommend explicitly waiting for it in your test and dismissing it as
+          a part of your normal test flow, instead of using `page.add_locator_handler()`.
+        - Playwright checks for the overlay every time before executing or retrying an action that requires an
+          [actionability check](https://playwright.dev/python/docs/actionability), or before performing an auto-waiting assertion check. When overlay
+          is visible, Playwright calls the handler first, and then proceeds with the action/assertion. Note that the
+          handler is only called when you perform an action/assertion - if the overlay becomes visible but you don't
+          perform any actions, the handler will not be triggered.
+        - After executing the handler, Playwright will ensure that overlay that triggered the handler is not visible
+          anymore. You can opt-out of this behavior with `noWaitAfter`.
+        - The execution time of the handler counts towards the timeout of the action/assertion that executed the handler.
+          If your handler takes too long, it might cause timeouts.
+        - You can register multiple handlers. However, only a single handler will be running at a time. Make sure the
+          actions within a handler don't depend on another handler.
+
+        **NOTE** Running the handler will alter your page state mid-test. For example it will change the currently focused
+        element and move the mouse. Make sure that actions that run after the handler are self-contained and do not rely on
+        the focus and mouse state being unchanged.
+
+        For example, consider a test that calls `locator.focus()` followed by `keyboard.press()`. If your
+        handler clicks a button between these two actions, the focused element most likely will be wrong, and key press
+        will happen on the unexpected element. Use `locator.press()` instead to avoid this problem.
+
+        Another example is a series of mouse actions, where `mouse.move()` is followed by `mouse.down()`.
+        Again, when the handler runs between these two actions, the mouse position will be wrong during the mouse down.
+        Prefer self-contained actions like `locator.click()` that do not rely on the state being unchanged by a
+        handler.
+
+        **Usage**
+
+        An example that closes a \"Sign up to the newsletter\" dialog when it appears:
+
+        ```py
+        # Setup the handler.
+        def handler():
+          page.get_by_role(\"button\", name=\"No thanks\").click()
+        page.add_locator_handler(page.get_by_text(\"Sign up to the newsletter\"), handler)
+
+        # Write the test as usual.
+        page.goto(\"https://example.com\")
+        page.get_by_role(\"button\", name=\"Start here\").click()
+        ```
+
+        An example that skips the \"Confirm your security details\" page when it is shown:
+
+        ```py
+        # Setup the handler.
+        def handler():
+          page.get_by_role(\"button\", name=\"Remind me later\").click()
+        page.add_locator_handler(page.get_by_text(\"Confirm your security details\"), handler)
+
+        # Write the test as usual.
+        page.goto(\"https://example.com\")
+        page.get_by_role(\"button\", name=\"Start here\").click()
+        ```
+
+        An example with a custom callback on every actionability check. It uses a `<body>` locator that is always visible,
+        so the handler is called before every actionability check. It is important to specify `noWaitAfter`, because the
+        handler does not hide the `<body>` element.
+
+        ```py
+        # Setup the handler.
+        def handler():
+          page.evaluate(\"window.removeObstructionsForTestIfNeeded()\")
+        page.add_locator_handler(page.locator(\"body\"), handler, no_wait_after=True)
+
+        # Write the test as usual.
+        page.goto(\"https://example.com\")
+        page.get_by_role(\"button\", name=\"Start here\").click()
+        ```
+
+        Handler takes the original locator as an argument. You can also automatically remove the handler after a number of
+        invocations by setting `times`:
+
+        ```py
+        def handler(locator):
+          locator.click()
+        page.add_locator_handler(page.get_by_label(\"Close\"), handler, times=1)
+        ```
+
+        Parameters
+        ----------
+        locator : Locator
+            Locator that triggers the handler.
+        handler : Union[Callable[[Locator], Any], Callable[[], Any]]
+            Function that should be run once `locator` appears. This function should get rid of the element that blocks actions
+            like click.
+        no_wait_after : Union[bool, None]
+            By default, after calling the handler Playwright will wait until the overlay becomes hidden, and only then
+            Playwright will continue with the action/assertion that triggered the handler. This option allows to opt-out of
+            this behavior, so that overlay can stay visible after the handler has run.
+        times : Union[int, None]
+            Specifies the maximum number of times this handler should be called. Unlimited by default.

+
+        Routing provides the capability to modify network requests that are made by any page in the browser context. Once
+        route is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.
+
+        **NOTE** `browser_context.route()` will not intercept requests intercepted by Service Worker. See
+        [this](https://github.com/microsoft/playwright/issues/1090) issue. We recommend disabling Service Workers when
+        using request interception by setting `serviceWorkers` to `'block'`.
+
+        **Usage**
+
+        An example of a naive handler that aborts all image requests:
+
+        ```py
+        context = await browser.new_context()
+        page = await context.new_page()
+        await context.route(\"**/*.{png,jpg,jpeg}\", lambda route: route.abort())
+        await page.goto(\"https://example.com\")
+        await browser.close()
+        ```
+
+        or the same snippet using a regex pattern instead:
+
+        ```py
+        context = await browser.new_context()
+        page = await context.new_page()
+        await context.route(re.compile(r\"(\\.png$)|(\\.jpg$)\"), lambda route: route.abort())
+        page = await context.new_page()
+        await page.goto(\"https://example.com\")
+        await browser.close()
+        ```
+
+        It is possible to examine the request to decide the route action. For example, mocking all requests that contain
+        some post data, and leaving all other requests as is:
+
+        ```py
+        async def handle_route(route: Route):
+          if (\"my-string\" in route.request.post_data):
+            await route.fulfill(body=\"mocked-data\")
+          else:
+            await route.continue_()
+        await context.route(\"/api/**\", handle_route)
+        ```
+
+        Page routes (set up with `page.route()`) take precedence over browser context routes when request matches
+        both handlers.
+
+        To remove a route with its handler you can use `browser_context.unroute()`.
+
+        **NOTE** Enabling routing disables http cache.

+        proxy : Union[{server: str, bypass: Union[str, None], username: Union[str, None], password: Union[str, None]}, None]
+            Network proxy settings to use with this context. Defaults to none.
+        record_har_path : Union[pathlib.Path, str, None]
+            Enables [HAR](http://www.softwareishard.com/blog/har-12-spec) recording for all pages into the specified HAR file
+            on the filesystem. If not specified, the HAR is not recorded. Make sure to call `browser_context.close()`
+            for the HAR to be saved.
+        record_har_omit_content : Union[bool, None]
+            Optional setting to control whether to omit request content from the HAR. Defaults to `false`.
+        record_video_dir : Union[pathlib.Path, str, None]
+            Enables video recording for all pages into the specified directory. If not specified videos are not recorded. Make
+            sure to call `browser_context.close()` for videos to be saved.
+        record_video_size : Union[{width: int, height: int}, None]
+            Dimensions of the recorded videos. If not specified the size will be equal to `viewport` scaled down to fit into
+            800x800. If `viewport` is not configured explicitly the video size defaults to 800x450. Actual picture of each page
+            will be scaled down if necessary to fit the specified size.
+        storage_state : Union[pathlib.Path, str, {cookies: Sequence[{name: str, value: str, domain: str, path: str, expires: float, httpOnly: bool, secure: bool, sameSite: Union["Lax", "None", "Strict"]}], origins: Sequence[{origin: str, localStorage: Sequence[{name: str, value: str}]}]}, None]
+            Learn more about [storage state and auth](../auth.md).
+
+            Populates context with given storage state. This option can be used to initialize context with logged-in
+            information obtained via `browser_context.storage_state()`.
+        base_url : Union[str, None]
+            When using `page.goto()`, `page.route()`, `page.wait_for_url()`,
+            `page.expect_request()`, or `page.expect_response()` it takes the base URL in consideration by
+            using the [`URL()`](https://developer.mozilla.org/en-US/docs/Web/API/URL/URL) constructor for building the
+            corresponding URL. Unset by default. Examples:
+            - baseURL: `http://localhost:3000` and navigating to `/bar.html` results in `http://localhost:3000/bar.html`
+            - baseURL: `http://localhost:3000/foo/` and navigating to `./bar.html` results in
+              `http://localhost:3000/foo/bar.html`
+            - baseURL: `http://localhost:3000/foo` (without trailing slash) and navigating to `./bar.html` results in
+              `http://localhost:3000/bar.html`
+        strict_selectors : Union[bool, None]
+            If set to true, enables strict selectors mode for this context. In the strict selectors mode all operations on
+            selectors that imply single target DOM element will throw when more than one element matches the selector. This
+            option does not affect any Locator APIs (Locators are always strict). Defaults to `false`. See `Locator` to learn
+            more about the strict mode.
+        service_workers : Union["allow", "block", None]
+            Whether to allow sites to register Service workers. Defaults to `'allow'`.

+        """Browser.new_page
+
+        Creates a new page in a new browser context. Closing this page will close the context as well.
+
+        This is a convenience API that should only be used for the single-page scenarios and short snippets. Production
+        code and testing frameworks should explicitly create `browser.new_context()` followed by the
+        `browser_context.new_page()` to control their exact life times.
+

+            Emulates `'prefers-reduced-motion'` media feature, supported values are `'reduce'`, `'no-preference'`. See
+            `page.emulate_media()` for more details. Passing `'null'` resets emulation to system defaults. Defaults to
+            `'no-preference'`.
+        accept_downloads : Union[bool, None]
+            Whether to automatically download all the attachments. Defaults to `true` where all the downloads are accepted.
+        proxy : Union[{server: str, bypass: Union[str, None], username: Union[str, None], password: Union[str, None]}, None]
+            Network proxy settings to use with this context. Defaults to none.
+        record_har_path : Union[pathlib.Path, str, None]
+            Enables [HAR](http://www.softwareishard.com/blog/har-12-spec) recording for all pages into the specified HAR file
+            on the filesystem. If not specified, the HAR is not recorded. Make sure to call `browser_context.close()`
+            for the HAR to be saved.
+        record_har_omit_content : Union[bool, None]
+            Optional setting to control whether to omit request content from the HAR. Defaults to `false`.
+        record_video_dir : Union[pathlib.Path, str, None]
+            Enables video recording for all pages into the specified directory. If not specified videos are not recorded. Make
+            sure to call `browser_context.close()` for videos to be saved.
+        record_video_size : Union[{width: int, height: int}, None]
+            Dimensions of the recorded videos. If not specified the size will be equal to `viewport` scaled down to fit into
+            800x800. If `viewport` is not configured explicitly the video size defaults to 800x450. Actual picture of each page
+            will be scaled down if necessary to fit the specified size.
+        storage_state : Union[pathlib.Path, str, {cookies: Sequence[{name: str, value: str, domain: str, path: str, expires: float, httpOnly: bool, secure: bool, sameSite: Union["Lax", "None", "Strict"]}], origins: Sequence[{origin: str, localStorage: Sequence[{name: str, value: str}]}]}, None]
+            Learn more about [storage state and auth](../auth.md).
+
+            Populates context with given storage state. This option can be used to initialize context with logged-in
+            information obtained via `browser_context.storage_state()`.
+        base_url : Union[str, None]
+            When using `page.goto()`, `page.route()`, `page.wait_for_url()`,
+            `page.expect_request()`, or `page.expect_response()` it takes the base URL in consideration by
+            using the [`URL()`](https://developer.mozilla.org/en-US/docs/Web/API/URL/URL) constructor for building the
+            corresponding URL. Unset by default. Examples:
+            - baseURL: `http://localhost:3000` and navigating to `/bar.html` results in `http://localhost:3000/bar.html`
+            - baseURL: `http://localhost:3000/foo/` and navigating to `./bar.html` results in
+              `http://localhost:3000/foo/bar.html`
+            - baseURL: `http://localhost:3000/foo` (without trailing slash) and navigating to `./bar.html` results in
+              `http://localhost:3000/bar.html`
+        strict_selectors : Union[bool, None]
+            If set to true, enables strict selectors mode for this context. In the strict selectors mode all operations on
+            selectors that imply single target DOM element will throw when more than one element matches the selector. This
+            option does not affect any Locator APIs (Locators are always strict). Defaults to `false`. See `Locator` to learn
+            more about the strict mode.
+        service_workers : Union["allow", "block", None]
+            Whether to allow sites to register Service workers. Defaults to `'allow'`.
+            - `'allow'`: [Service Workers](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API) can be
+              registered.
+            - `'block'`: Playwright will block all registration of Service Workers.
+        record_har_url_filter : Union[Pattern[str], str, None]
+        record_har_mode : Union["full", "minimal", None]
+            When set to `minimal`, only record information necessary for routing from HAR. This omits sizes, timing, page,
+            cookies, security and other types of HAR information that are not used when replaying from HAR. Defaults to `full`.
+        record_har_content : Union["attach", "embed", "omit", None]
+            Optional setting to control resource content management. If `omit` is specified, content is not persisted. If
+            `attach` is specified, resources are persisted as separate files and all of these files are archived along with the

+
+        Parameters
+        ----------
+        executable_path : Union[pathlib.Path, str, None]
+            Path to a browser executable to run instead of the bundled one. If `executablePath` is a relative path, then it is
+            resolved relative to the current working directory. Note that Playwright only works with the bundled Chromium,
+            Firefox or WebKit, use at your own risk.
+        channel : Union[str, None]
+            Browser distribution channel.
+
+            Use "chromium" to [opt in to new headless mode](../browsers.md#chromium-new-headless-mode).
+
+            Use "chrome", "chrome-beta", "chrome-dev", "chrome-canary", "msedge", "msedge-beta", "msedge-dev", or
+            "msedge-canary" to use branded [Google Chrome and Microsoft Edge](../browsers.md#google-chrome--microsoft-edge).
+        args : Union[Sequence[str], None]
+            **NOTE** Use custom browser args at your own risk, as some of them may break Playwright functionality.
+
+            Additional arguments to pass to the browser instance. The list of Chromium flags can be found
+            [here](https://peter.sh/experiments/chromium-command-line-switches/).
+        ignore_default_args : Union[Sequence[str], bool, None]
+            If `true`, Playwright does not pass its own configurations args and only uses the ones from `args`. If an array is
+            given, then filters out the given default arguments. Dangerous option; use with care. Defaults to `false`.
+        handle_sigint : Union[bool, None]
+            Close the browser process on Ctrl-C. Defaults to `true`.
+        handle_sigterm : Union[bool, None]
+            Close the browser process on SIGTERM. Defaults to `true`.
+        handle_sighup : Union[bool, None]
+            Close the browser process on SIGHUP. Defaults to `true`.
+        timeout : Union[float, None]
+            Maximum time in milliseconds to wait for the browser instance to start. Defaults to `30000` (30 seconds). Pass `0`
+            to disable timeout.
+        env : Union[Dict[str, Union[bool, float, str]], None]
+            Specify environment variables that will be visible to the browser. Defaults to `process.env`.
+        headless : Union[bool, None]
+            Whether to run browser in headless mode. More details for
+            [Chromium](https://developers.google.com/web/updates/2017/04/headless-chrome) and
+            [Firefox](https://hacks.mozilla.org/2017/12/using-headless-mode-in-firefox/). Defaults to `true` unless the
+            `devtools` option is `true`.
+        devtools : Union[bool, None]
+            **Chromium-only** Whether to auto-open a Developer Tools panel for each tab. If this option is `true`, the
+            `headless` option will be set `false`.
+            Deprecated: Use [debugging tools](../debug.md) instead.
+        proxy : Union[{server: str, bypass: Union[str, None], username: Union[str, None], password: Union[str, None]}, None]
+            Network proxy settings.
+        downloads_path : Union[pathlib.Path, str, None]
+            If specified, accepted downloads are downloaded into this directory. Otherwise, temporary directory is created and
+            is deleted when browser is closed. In either case, the downloads are deleted when the browser context they were
+            created in is closed.
+        slow_mo : Union[float, None]
+            Slows down Playwright operations by the specified amount of milliseconds. Useful so that you can see what is going
+            on.
+        traces_dir : Union[pathlib.Path, str, None]
+            If specified, traces are saved into this directory.
+        chromium_sandbox : Union[bool, None]
+            Enable Chromium sandboxing. Defaults to `false`.
+        firefox_user_prefs : Union[Dict[str, Union[bool, float, str]], None]
+            Firefox user preferences. Learn more about the Firefox user preferences at
+            [`about:config`](https://support.mozilla.org/en-US/kb/about-config-editor-firefox).
+
+            You can also provide a path to a custom [`policies.json` file](https://mozilla.github.io/policy-templates/) via

+        record_har_path : Union[pathlib.Path, str, None]
+            Enables [HAR](http://www.softwareishard.com/blog/har-12-spec) recording for all pages into the specified HAR file
+            on the filesystem. If not specified, the HAR is not recorded. Make sure to call `browser_context.close()`
+            for the HAR to be saved.
+        record_har_omit_content : Union[bool, None]
+            Optional setting to control whether to omit request content from the HAR. Defaults to `false`.
+        record_video_dir : Union[pathlib.Path, str, None]
+            Enables video recording for all pages into the specified directory. If not specified videos are not recorded. Make
+            sure to call `browser_context.close()` for videos to be saved.
+        record_video_size : Union[{width: int, height: int}, None]
+            Dimensions of the recorded videos. If not specified the size will be equal to `viewport` scaled down to fit into
+            800x800. If `viewport` is not configured explicitly the video size defaults to 800x450. Actual picture of each page
+            will be scaled down if necessary to fit the specified size.
+        base_url : Union[str, None]
+            When using `page.goto()`, `page.route()`, `page.wait_for_url()`,
+            `page.expect_request()`, or `page.expect_response()` it takes the base URL in consideration by
+            using the [`URL()`](https://developer.mozilla.org/en-US/docs/Web/API/URL/URL) constructor for building the
+            corresponding URL. Unset by default. Examples:
+            - baseURL: `http://localhost:3000` and navigating to `/bar.html` results in `http://localhost:3000/bar.html`
+            - baseURL: `http://localhost:3000/foo/` and navigating to `./bar.html` results in
+              `http://localhost:3000/foo/bar.html`
+            - baseURL: `http://localhost:3000/foo` (without trailing slash) and navigating to `./bar.html` results in
+              `http://localhost:3000/bar.html`
+        strict_selectors : Union[bool, None]
+            If set to true, enables strict selectors mode for this context. In the strict selectors mode all operations on
+            selectors that imply single target DOM element will throw when more than one element matches the selector. This
+            option does not affect any Locator APIs (Locators are always strict). Defaults to `false`. See `Locator` to learn
+            more about the strict mode.
+        service_workers : Union["allow", "block", None]
+            Whether to allow sites to register Service workers. Defaults to `'allow'`.
+            - `'allow'`: [Service Workers](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API) can be
+              registered.
+            - `'block'`: Playwright will block all registration of Service Workers.
+        record_har_url_filter : Union[Pattern[str], str, None]
+        record_har_mode : Union["full", "minimal", None]
+            When set to `minimal`, only record information necessary for routing from HAR. This omits sizes, timing, page,
+            cookies, security and other types of HAR information that are not used when replaying from HAR. Defaults to `full`.
+        record_har_content : Union["attach", "embed", "omit", None]
+            Optional setting to control resource content management. If `omit` is specified, content is not persisted. If
+            `attach` is specified, resources are persisted as separate files and all of these files are archived along with the
+            HAR file. Defaults to `embed`, which stores content inline the HAR file as per HAR specification.
+        client_certificates : Union[Sequence[{origin: str, certPath: Union[pathlib.Path, str, None], cert: Union[bytes, None], keyPath: Union[pathlib.Path, str, None], key: Union[bytes, None], pfxPath: Union[pathlib.Path, str, None], pfx: Union[bytes, None], passphrase: Union[str, None]}], None]
+            TLS Client Authentication allows the server to request a client certificate and verify it.
+
+            **Details**
+
+            An array of client certificates to be used. Each certificate object must have either both `certPath` and `keyPath`,
+            a single `pfxPath`, or their corresponding direct value equivalents (`cert` and `key`, or `pfx`). Optionally,
+            `passphrase` property should be provided if the certificate is encrypted. The `origin` property should be provided
+            with an exact match to the request origin that the certificate is valid for.
+
+            **NOTE** When using WebKit on macOS, accessing `localhost` will not pick up client certificates. You can make it
+            work by replacing `localhost` with `local.playwright`.

+
+        **Details**
+

+        1. Scroll the element into view if needed.

+
+        If the element is detached from the DOM at any moment during the action, this method throws.
+
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.
+        Passing zero timeout disables this.
+
+        **NOTE** `element.dblclick()` dispatches two `click` events and a single `dblclick` event.

+
+        **Details**
+
+        The snippet above dispatches the `click` event on the element. Regardless of the visibility state of the element,
+        `click` is dispatched. This is equivalent to calling
+        [element.click()](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click).
+
+        Under the hood, it creates an instance of an event based on the given `type`, initializes it with `eventInit`
+        properties and dispatches it on the element. Events are `composed`, `cancelable` and bubble by default.
+
+        Since `eventInit` is event-specific, please refer to the events documentation for the lists of initial properties:
+        - [DeviceMotionEvent](https://developer.mozilla.org/en-US/docs/Web/API/DeviceMotionEvent/DeviceMotionEvent)
+        - [DeviceOrientationEvent](https://developer.mozilla.org/en-US/docs/Web/API/DeviceOrientationEvent/DeviceOrientationEvent)
+        - [DragEvent](https://developer.mozilla.org/en-US/docs/Web/API/DragEvent/DragEvent)
+        - [Event](https://developer.mozilla.org/en-US/docs/Web/API/Event/Event)
+        - [FocusEvent](https://developer.mozilla.org/en-US/docs/Web/API/FocusEvent/FocusEvent)
+        - [KeyboardEvent](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/KeyboardEvent)
+        - [MouseEvent](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/MouseEvent)

+
+        You can also specify `JSHandle` as the property value if you want live objects to be passed into the event:

+        has : Union[Locator, None]
+            Narrows down the results of the method to those which contain elements matching this relative locator. For example,
+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in
+            `<article><content><div>Playwright</div></content></article>`. However, looking for `content` that has `article
+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the
+            outer one. For example, `article` that does not have `div` matches `<article><span>Playwright</span></article>`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.

+        include_hidden : Union[bool, None]
+            Option that controls whether hidden elements are matched. By default, only non-hidden elements, as
+            [defined by ARIA](https://www.w3.org/TR/wai-aria-1.2/#tree_exclusion), are matched by role selector.

+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in

+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the

+
+        `key` can specify the intended
+        [keyboardEvent.key](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key) value or a single character
+        to generate the text for. A superset of the `key` values can be found
+        [here](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values). Examples of the keys are:
+
+        `F1` - `F12`, `Digit0`- `Digit9`, `KeyA`- `KeyZ`, `Backquote`, `Minus`, `Equal`, `Backslash`, `Backspace`, `Tab`,
+        `Delete`, `Escape`, `ArrowDown`, `End`, `Enter`, `Home`, `Insert`, `PageDown`, `PageUp`, `ArrowRight`, `ArrowUp`,
+        etc.
+
+        Following modification shortcuts are also supported: `Shift`, `Control`, `Alt`, `Meta`, `ShiftLeft`,
+        `ControlOrMeta`. `ControlOrMeta` resolves to `Control` on Windows and Linux and to `Meta` on macOS.
+
+        Holding down `Shift` will type the text that corresponds to the `key` in the upper case.
+
+        If `key` is a single character, it is case-sensitive, so the values `a` and `A` will generate different respective
+        texts.
+
+        Shortcuts such as `key: \"Control+o\"`, `key: \"Control++` or `key: \"Control+Shift+T\"` are supported as well. When
+        specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.
+
+        Parameters
+        ----------
+        key : str

+
+        This method captures a screenshot of the page, clipped to the size and position of a particular element matching

+        type : Union["jpeg", "png", None]
+            Specify screenshot type, defaults to `png`.
+        path : Union[pathlib.Path, str, None]
+            The file path to save the image to. The screenshot type will be inferred from file extension. If `path` is a
+            relative path, then it is resolved relative to the current working directory. If no path is provided, the image
+            won't be saved to the disk.
+        quality : Union[int, None]
+            The quality of the image, between 0-100. Not applicable to `png` images.
+        omit_background : Union[bool, None]
+            Hides default white background and allows capturing screenshots with transparency. Not applicable to `jpeg` images.
+            Defaults to `false`.
+        animations : Union["allow", "disabled", None]
+            When set to `"disabled"`, stops CSS animations, CSS transitions and Web Animations. Animations get different
+            treatment depending on their duration:
+            - finite animations are fast-forwarded to completion, so they'll fire `transitionend` event.
+            - infinite animations are canceled to initial state, and then played over after the screenshot.
+
+            Defaults to `"allow"` that leaves animations untouched.
+        caret : Union["hide", "initial", None]
+            When set to `"hide"`, screenshot will hide text caret. When set to `"initial"`, text caret behavior will not be
+            changed.  Defaults to `"hide"`.
+        scale : Union["css", "device", None]
+            When set to `"css"`, screenshot will have a single pixel per each css pixel on the page. For high-dpi devices, this
+            will keep screenshots small. Using `"device"` option will produce a single pixel per each device pixel, so
+            screenshots of high-dpi devices will be twice as large or even larger.
+
+            Defaults to `"device"`.
+        mask : Union[Sequence[Locator], None]
+            Specify locators that should be masked when the screenshot is taken. Masked elements will be overlaid with a pink
+            box `#FF00FF` (customized by `maskColor`) that completely covers its bounding box. The mask is also applied to
+            invisible elements, see [Matching only visible elements](../locators.md#matching-only-visible-elements) to disable
+            that.
+        mask_color : Union[str, None]
+            Specify the color of the overlay box for masked elements, in

+
+        **Details**
+
+        This method taps the element by performing the following steps:
+        1. Wait for [actionability](https://playwright.dev/python/docs/actionability) checks on the element, unless `force` option is set.
+        1. Scroll the element into view if needed.
+        1. Use `page.touchscreen` to tap the center of the element, or the specified `position`.
+
+        If the element is detached from the DOM at any moment during the action, this method throws.
+
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.
+        Passing zero timeout disables this.
+
+        **NOTE** `element.tap()` requires that the `hasTouch` option of the browser context be set to true.

-        This method taps an element matching `selector` by performing the following steps:
-        1. Find an element match matching `selector`. If there is none, wait until a matching element is attached to the DOM.
-        1. Wait for [actionability](./actionability.md) checks on the matched element, unless `force` option is set. If the
-           element is detached during the checks, the whole action is retried.
-        1. Scroll the element into view if needed.
-        1. Use `page.touchscreen` to tap the center of the element, or the specified `position`.
-        1. Wait for initiated navigations to either succeed or fail, unless `noWaitAfter` option is set.

         ----------
-        selector : str
-            A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See
-            [working with selectors](./selectors.md#working-with-selectors) for more details.
-        value : str
-            Value to fill for the `<input>`, `<textarea>` or `[contenteditable]` element.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
-        no_wait_after : Union[bool, NoneType]
-            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can
-            opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as navigating to
-            inaccessible pages. Defaults to `false`.

         Parameters
         ----------
-        selector : str
-            A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See
-            [working with selectors](./selectors.md#working-with-selectors) for more details.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        url_or_request : Union[Request, str]
+            Target URL or Request to get all parameters from.
+        params : Union[Dict[str, Union[bool, float, str]], str, None]
+            Query parameters to be sent with the URL.
+        method : Union[str, None]
+            If set changes the fetch method (e.g. [PUT](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT) or
+            [POST](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST)). If not specified, GET method is used.
+        headers : Union[Dict[str, str], None]
+            Allows to set HTTP headers. These headers will apply to the fetched request as well as any redirects initiated by
+            it.
+        data : Union[Any, bytes, str, None]
+            Allows to set post data of the request. If the data parameter is an object, it will be serialized to json string
+            and `content-type` header will be set to `application/json` if not explicitly set. Otherwise the `content-type`
+            header will be set to `application/octet-stream` if not explicitly set.
+        form : Union[Dict[str, Union[bool, float, str]], None]
+            Provides an object that will be serialized as html form using `application/x-www-form-urlencoded` encoding and sent
+            as this request body. If this parameter is specified `content-type` header will be set to
+            `application/x-www-form-urlencoded` unless explicitly provided.
+        multipart : Union[Dict[str, Union[bool, bytes, float, str, {name: str, mimeType: str, buffer: bytes}]], None]
+            Provides an object that will be serialized as html form using `multipart/form-data` encoding and sent as this
+            request body. If this parameter is specified `content-type` header will be set to `multipart/form-data` unless
+            explicitly provided. File values can be passed as file-like object containing file name, mime-type and its content.
+        timeout : Union[float, None]
+            Request timeout in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout.
+        fail_on_status_code : Union[bool, None]
+            Whether to throw on response codes other than 2xx and 3xx. By default response object is returned for all status
+            codes.
+        ignore_https_errors : Union[bool, None]
+            Whether to ignore HTTPS errors when sending network requests. Defaults to `false`.
+        max_redirects : Union[int, None]
+            Maximum number of request redirects that will be followed automatically. An error will be thrown if the number is
+            exceeded. Defaults to `20`. Pass `0` to not follow redirects.
+        max_retries : Union[int, None]
+            Maximum number of times network errors should be retried. Currently only `ECONNRESET` error is retried. Does not
+            retry based on HTTP response codes. An error will be thrown if the limit is exceeded. Defaults to `0` - no retries.

-        name : str
-            Attribute name to get the value for.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        base_url : Union[str, None]
+            Methods like `a_pi_request_context.get()` take the base URL into consideration by using the
+            [`URL()`](https://developer.mozilla.org/en-US/docs/Web/API/URL/URL) constructor for building the corresponding URL.
+            Examples:
+            - baseURL: `http://localhost:3000` and sending request to `/bar.html` results in `http://localhost:3000/bar.html`
+            - baseURL: `http://localhost:3000/foo/` and sending request to `./bar.html` results in
+              `http://localhost:3000/foo/bar.html`
+            - baseURL: `http://localhost:3000/foo` (without trailing slash) and navigating to `./bar.html` results in
+              `http://localhost:3000/bar.html`
+        extra_http_headers : Union[Dict[str, str], None]
+            An object containing additional HTTP headers to be sent with every request. Defaults to none.
+        http_credentials : Union[{username: str, password: str, origin: Union[str, None], send: Union["always", "unauthorized", None]}, None]
+            Credentials for [HTTP authentication](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication). If no
+            origin is specified, the username and password are sent to any servers upon unauthorized responses.
+        ignore_https_errors : Union[bool, None]
+            Whether to ignore HTTPS errors when sending network requests. Defaults to `false`.
+        proxy : Union[{server: str, bypass: Union[str, None], username: Union[str, None], password: Union[str, None]}, None]
+            Network proxy settings.
+        user_agent : Union[str, None]
+            Specific user agent to use in this context.
+        timeout : Union[float, None]
+            Maximum time in milliseconds to wait for the response. Defaults to `30000` (30 seconds). Pass `0` to disable
+            timeout.
+        storage_state : Union[pathlib.Path, str, {cookies: Sequence[{name: str, value: str, domain: str, path: str, expires: float, httpOnly: bool, secure: bool, sameSite: Union["Lax", "None", "Strict"]}], origins: Sequence[{origin: str, localStorage: Sequence[{name: str, value: str}]}]}, None]
+            Populates context with given storage state. This option can be used to initialize context with logged-in
+            information obtained via `browser_context.storage_state()` or `a_pi_request_context.storage_state()`.
+            Either a path to the file with saved storage, or the value returned by one of
+            `browser_context.storage_state()` or `a_pi_request_context.storage_state()` methods.
+        client_certificates : Union[Sequence[{origin: str, certPath: Union[pathlib.Path, str, None], cert: Union[bytes, None], keyPath: Union[pathlib.Path, str, None], key: Union[bytes, None], pfxPath: Union[pathlib.Path, str, None], pfx: Union[bytes, None], passphrase: Union[str, None]}], None]
+            TLS Client Authentication allows the server to request a client certificate and verify it.
+
+            **Details**
+
+            An array of client certificates to be used. Each certificate object must have either both `certPath` and `keyPath`,
+            a single `pfxPath`, or their corresponding direct value equivalents (`cert` and `key`, or `pfx`). Optionally,
+            `passphrase` property should be provided if the certificate is encrypted. The `origin` property should be provided
+            with an exact match to the request origin that the certificate is valid for.
+
+            **NOTE** When using WebKit on macOS, accessing `localhost` will not pick up client certificates. You can make it
+            work by replacing `localhost` with `local.playwright`.
+
+        fail_on_status_code : Union[bool, None]
+            Whether to throw on response codes other than 2xx and 3xx. By default response object is returned for all status
+            codes.
+        max_redirects : Union[int, None]
+            Maximum number of request redirects that will be followed automatically. An error will be thrown if the number is
+            exceeded. Defaults to `20`. Pass `0` to not follow redirects. This can be overwritten for each request
+            individually.

-        Focuses the element, and then uses `keyboard.down()` and `keyboard.up()`.
+        Ensures the `Locator` points to an element that contains the given text. All nested elements will be considered
+        when computing the text content of the element. You can use regular expressions for the value as well.
 
-        `key` can specify the intended [keyboardEvent.key](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key)
-        value or a single character to generate the text for. A superset of the `key` values can be found
-        [here](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values). Examples of the keys are:
+        **Details**
 
-        `F1` - `F12`, `Digit0`- `Digit9`, `KeyA`- `KeyZ`, `Backquote`, `Minus`, `Equal`, `Backslash`, `Backspace`, `Tab`,
-        `Delete`, `Escape`, `ArrowDown`, `End`, `Enter`, `Home`, `Insert`, `PageDown`, `PageUp`, `ArrowRight`, `ArrowUp`, etc.
+        When `expected` parameter is a string, Playwright will normalize whitespaces and line breaks both in the actual
+        text and in the expected string before matching. When regular expression is used, the actual text is matched as is.
 
-        Following modification shortcuts are also supported: `Shift`, `Control`, `Alt`, `Meta`, `ShiftLeft`.
+        **Usage**
 
-        Holding down `Shift` will type the text that corresponds to the `key` in the upper case.
+        ```py
+        import re
+        from playwright.async_api import expect
 
-        If `key` is a single character, it is case-sensitive, so the values `a` and `A` will generate different respective
-        texts.
+        locator = page.locator('.title')
+        await expect(locator).to_contain_text(\"substring\")
+        await expect(locator).to_contain_text(re.compile(r\"\\d messages\"))
+        ```
 
-        Shortcuts such as `key: "Control+o"` or `key: "Control+Shift+T"` are supported as well. When speficied with the
-        modifier, modifier is pressed and being held while the subsequent key is being pressed.
+        If you pass an array as an expected value, the expectations are:
+        1. Locator resolves to a list of elements.
+        1. Elements from a **subset** of this list contain text from the expected array, respectively.
+        1. The matching subset of elements has the same order as the expected array.
+        1. Each text value from the expected array is matched by some element from the list.
+
+        For example, consider the following list:
+
+        ```html
+        <ul>
+          <li>Item Text 1</li>
+          <li>Item Text 2</li>
+          <li>Item Text 3</li>
+        </ul>
+        ```
+
+        Let's see how we can use the assertion:
+
+        ```py
+        from playwright.async_api import expect
+
+        # ✓ Contains the right items in the right order
+        await expect(page.locator(\"ul > li\")).to_contain_text([\"Text 1\", \"Text 3\", \"Text 4\"])
+
+        # ✖ Wrong order
+        await expect(page.locator(\"ul > li\")).to_contain_text([\"Text 3\", \"Text 2\"])
+
+        # ✖ No item contains this text
+        await expect(page.locator(\"ul > li\")).to_contain_text([\"Some 33\"])
+
+        # ✖ Locator points to the outer list element, not to the list items
+        await expect(page.locator(\"ul\")).to_contain_text([\"Text 3\"])
+        ```

-        This method checks an element matching `selector` by performing the following steps:
-        1. Find an element match matching `selector`. If there is none, wait until a matching element is attached to the DOM.
-        1. Ensure that matched element is a checkbox or a radio input. If not, this method rejects. If the element is already
-           checked, this method returns immediately.
-        1. Wait for [actionability](./actionability.md) checks on the matched element, unless `force` option is set. If the
-           element is detached during the checks, the whole action is retried.
-        1. Scroll the element into view if needed.
-        1. Use `page.mouse` to click in the center of the element.
-        1. Wait for initiated navigations to either succeed or fail, unless `noWaitAfter` option is set.
-        1. Ensure that the element is now checked. If not, this method rejects.

-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
-        force : Union[bool, NoneType]
-            Whether to bypass the [actionability](./actionability.md) checks. Defaults to `false`.
-        no_wait_after : Union[bool, NoneType]
-            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can

-            Paper ranges to print, e.g., '1-5, 8, 11-13'. Defaults to the empty string, which means print all pages.
-        format : Union[str, NoneType]
-            Paper format. If set, takes priority over `width` or `height` options. Defaults to 'Letter'.
-        width : Union[float, str, NoneType]
-            Paper width, accepts values labeled with units.
-        height : Union[float, str, NoneType]
-            Paper height, accepts values labeled with units.
-        prefer_css_page_size : Union[bool, NoneType]
-            Give any CSS `@page` size declared in the page priority over what is declared in `width` and `height` or `format`
-            options. Defaults to `false`, which will scale the content to fit the paper size.
-        margin : Union[{top: Union[float, str, NoneType], right: Union[float, str, NoneType], bottom: Union[float, str, NoneType], left: Union[float, str, NoneType]}, NoneType]
-            Paper margins, defaults to none.
-        path : Union[pathlib.Path, str, NoneType]
-            The file path to save the PDF to. If `path` is a relative path, then it is resolved relative to the current working
-            directory. If no path is provided, the PDF won't be saved to the disk.

         Parameters
         ----------
-        executable_path : Union[pathlib.Path, str, NoneType]
-            Path to a browser executable to run instead of the bundled one. If `executablePath` is a relative path, then it is
-            resolved relative to the current working directory. Note that Playwright only works with the bundled Chromium, Firefox
-            or WebKit, use at your own risk.
-        args : Union[List[str], NoneType]
-            Additional arguments to pass to the browser instance. The list of Chromium flags can be found
-            [here](http://peter.sh/experiments/chromium-command-line-switches/).
-        ignore_default_args : Union[List[str], bool, NoneType]
-            If `true`, Playwright does not pass its own configurations args and only uses the ones from `args`. If an array is
-            given, then filters out the given default arguments. Dangerous option; use with care. Defaults to `false`.
-        handle_sigint : Union[bool, NoneType]
-            Close the browser process on Ctrl-C. Defaults to `true`.
-        handle_sigterm : Union[bool, NoneType]
-            Close the browser process on SIGTERM. Defaults to `true`.
-        handle_sighup : Union[bool, NoneType]
-            Close the browser process on SIGHUP. Defaults to `true`.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds to wait for the browser instance to start. Defaults to `30000` (30 seconds). Pass `0` to
-            disable timeout.
-        env : Union[Dict[str, Union[bool, float, str]], NoneType]
-            Specify environment variables that will be visible to the browser. Defaults to `process.env`.
-        headless : Union[bool, NoneType]
-            Whether to run browser in headless mode. More details for
-            [Chromium](https://developers.google.com/web/updates/2017/04/headless-chrome) and
-            [Firefox](https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Headless_mode). Defaults to `true` unless the
-            `devtools` option is `true`.
-        devtools : Union[bool, NoneType]
-            **Chromium-only** Whether to auto-open a Developer Tools panel for each tab. If this option is `true`, the `headless`
-            option will be set `false`.
-        proxy : Union[{server: str, bypass: Union[str, NoneType], username: Union[str, NoneType], password: Union[str, NoneType]}, NoneType]
-            Network proxy settings.
-        downloads_path : Union[pathlib.Path, str, NoneType]
-            If specified, accepted downloads are downloaded into this directory. Otherwise, temporary directory is created and is
-            deleted when browser is closed.
-        slow_mo : Union[float, NoneType]
-            Slows down Playwright operations by the specified amount of milliseconds. Useful so that you can see what is going on.
-        chromium_sandbox : Union[bool, NoneType]
-            Enable Chromium sandboxing. Defaults to `false`.
-        firefox_user_prefs : Union[Dict[str, Union[bool, float, str]], NoneType]
-            Firefox user preferences. Learn more about the Firefox user preferences at
-            [`about:config`](https://support.mozilla.org/en-US/kb/about-config-editor-firefox).

+        post_data : Union[Any, bytes, str, None]
+            Allows to set post data of the request. If the data parameter is an object, it will be serialized to json string

+
+        Continues route's request with optional overrides. The method is similar to `route.continue_()` with the
+        difference that other matching handlers will be invoked before sending the request.
+
+        **Usage**
+
+        When several routes match the given pattern, they run in the order opposite to their registration. That way the
+        last registered route can always override all the previous ones. In the example below, request will be handled by
+        the bottom-most handler first, then it'll fall back to the previous one and in the end will be aborted by the first
+        registered route.
+
+        ```py
+        page.route(\"**/*\", lambda route: route.abort())  # Runs last.
+        page.route(\"**/*\", lambda route: route.fallback())  # Runs second.
+        page.route(\"**/*\", lambda route: route.fallback())  # Runs first.
+        ```
+
+        Registering multiple routes is useful when you want separate handlers to handle different kinds of requests, for
+        example API calls vs page resources or GET requests vs POST requests as in the example below.
+
+        ```py
+        # Handle GET requests.
+        def handle_get(route):
+            if route.request.method != \"GET\":
+                route.fallback()
+                return
+          # Handling GET only.
+          # ...
+
+        # Handle POST requests.
+        def handle_post(route):
+            if route.request.method != \"POST\":
+                route.fallback()
+                return
+          # Handling POST only.
+          # ...
+
+        page.route(\"**/*\", handle_get)
+        page.route(\"**/*\", handle_post)
+        ```
+
+        One can also modify request while falling back to the subsequent handler, that way intermediate route handler can
+        modify url, method, headers and postData of the request.
+
+        ```py
+        def handle(route, request):
+            # override headers
+            headers = {
+                **request.headers,
+                \"foo\": \"foo-value\", # set \"foo\" header
+                \"bar\": None # remove \"bar\" header
+            }
+            route.fallback(headers=headers)
+
+        page.route(\"**/*\", handle)
+        ```
+
+        Use `route.continue_()` to immediately send the request to the network, other matching handlers won't be
+        invoked in that case.
+
+        Parameters
+        ----------
+        url : Union[str, None]
+            If set changes the request URL. New URL must have same protocol as original one. Changing the URL won't affect the
+            route matching, all the routes are matched using the original request URL.

+            If set changes the request method (e.g. GET or POST).

         """Route.continue_
 
-        Continues route's request with optional overrides.
+        Sends route's request to the network with optional overrides.
+
+        **Usage**
+
+        ```py
+        def handle(route, request):
+            # override headers
+            headers = {
+                **request.headers,
+                \"foo\": \"foo-value\", # set \"foo\" header
+                \"bar\": None # remove \"bar\" header
+            }
+            route.continue_(headers=headers)
+
+        page.route(\"**/*\", handle)
+        ```
+
+        **Details**
+
+        The `headers` option applies to both the routed request and any redirects it initiates. However, `url`, `method`,
+        and `postData` only apply to the original request and are not carried over to redirected requests.
+
+        `route.continue_()` will immediately send the request to the network, other matching handlers won't be
+        invoked. Use `route.fallback()` If you want next matching handler in the chain to be invoked.
+
+        **NOTE** The `Cookie` header cannot be overridden using this method. If a value is provided, it will be ignored,
+        and the cookie will be loaded from the browser's cookie store. To set custom cookies, use
+        `browser_context.add_cookies()`.
 
         Parameters
         ----------
-        url : Union[str, NoneType]
+        url : Union[str, None]
             If set changes the request URL. New URL must have same protocol as original one.
-        method : Union[str, NoneType]
-            If set changes the request method (e.g. GET or POST)
-        headers : Union[Dict[str, str], NoneType]
+        method : Union[str, None]
+            If set changes the request method (e.g. GET or POST).
+        headers : Union[Dict[str, str], None]
             If set changes the request HTTP headers. Header values will be converted to a string.
-        post_data : Union[bytes, str, NoneType]
-            If set changes the post data of request
+        post_data : Union[Any, bytes, str, None]

-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
-        force : Union[bool, NoneType]
-            Whether to bypass the [actionability](./actionability.md) checks. Defaults to `false`.
-        no_wait_after : Union[bool, NoneType]
-            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can

         Parameters
         ----------

-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
-        type : Union["jpeg", "png", NoneType]
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        type : Union["jpeg", "png", None]
             Specify screenshot type, defaults to `png`.
-        path : Union[pathlib.Path, str, NoneType]
-            The file path to save the image to. The screenshot type will be inferred from file extension. If `path` is a relative
-            path, then it is resolved relative to the current working directory. If no path is provided, the image won't be saved to
-            the disk.
-        quality : Union[int, NoneType]
+        path : Union[pathlib.Path, str, None]
+            The file path to save the image to. The screenshot type will be inferred from file extension. If `path` is a
+            relative path, then it is resolved relative to the current working directory. If no path is provided, the image
+            won't be saved to the disk.
+        quality : Union[int, None]
             The quality of the image, between 0-100. Not applicable to `png` images.
-        omit_background : Union[bool, NoneType]
+        omit_background : Union[bool, None]
             Hides default white background and allows capturing screenshots with transparency. Not applicable to `jpeg` images.
             Defaults to `false`.
+        animations : Union["allow", "disabled", None]
+            When set to `"disabled"`, stops CSS animations, CSS transitions and Web Animations. Animations get different
+            treatment depending on their duration:
+            - finite animations are fast-forwarded to completion, so they'll fire `transitionend` event.
+            - infinite animations are canceled to initial state, and then played over after the screenshot.
+
+            Defaults to `"allow"` that leaves animations untouched.
+        caret : Union["hide", "initial", None]
+            When set to `"hide"`, screenshot will hide text caret. When set to `"initial"`, text caret behavior will not be
+            changed.  Defaults to `"hide"`.
+        scale : Union["css", "device", None]
+            When set to `"css"`, screenshot will have a single pixel per each css pixel on the page. For high-dpi devices, this
+            will keep screenshots small. Using `"device"` option will produce a single pixel per each device pixel, so
+            screenshots of high-dpi devices will be twice as large or even larger.
+
+            Defaults to `"device"`.
+        mask : Union[Sequence[Locator], None]
+            Specify locators that should be masked when the screenshot is taken. Masked elements will be overlaid with a pink

-        wait_until : Union["domcontentloaded", "load", "networkidle", NoneType]
+        url : Union[Callable[[str], bool], Pattern[str], str, None]
+            A glob pattern, regex pattern or predicate receiving [URL] to match while waiting for the navigation. Note that if

-            - `'networkidle'` - consider operation to be finished when there are no network connections for at least `500` ms.
-        timeout : Union[float, NoneType]
-            Maximum operation time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be

-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
-        state : Union["attached", "detached", "hidden", "visible", NoneType]
+            A selector to query for.
+        strict : Union[bool, None]
+            When true, the call requires selector to resolve to a single element. If given selector resolves to more than one
+            element, the call throws an exception.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can

+        state : Union["attached", "detached", "hidden", "visible", None]
             Defaults to `'visible'`. Can be either:
             - `'attached'` - wait for element to be present in DOM.
             - `'detached'` - wait for element to not be present in DOM.
-            - `'visible'` - wait for element to have non-empty bounding box and no `visibility:hidden`. Note that element without
-              any content or with `display:none` has an empty bounding box and is not considered visible.
-            - `'hidden'` - wait for element to be either detached from DOM, or have an empty bounding box or `visibility:hidden`.
-              This is opposite to the `'visible'` option.

-        modifiers : Union[List[Union["Alt", "Control", "Meta", "Shift"]], NoneType]
-            Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores current
-            modifiers back. If not specified, currently pressed modifiers are used.
-        position : Union[typing.Tuple[float, float], NoneType]
-            A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of the
-            element.
-        delay : Union[float, NoneType]
+            A selector to search for an element. If there are multiple elements satisfying the selector, the first will be
+            used.
+        modifiers : Union[Sequence[Union["Alt", "Control", "ControlOrMeta", "Meta", "Shift"]], None]
+            Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores
+            current modifiers back. If not specified, currently pressed modifiers are used. "ControlOrMeta" resolves to
+            "Control" on Windows and Linux and to "Meta" on macOS.
+        position : Union[{x: float, y: float}, None]

         selector : str
-            A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See
-            [working with selectors](./selectors.md#working-with-selectors) for more details.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+            A selector to use when resolving DOM element.
+        has_text : Union[Pattern[str], str, None]
+            Matches elements containing specified text somewhere inside, possibly in a child or a descendant element. When
+            passed a [string], matching is case-insensitive and searches for a substring. For example, `"Playwright"` matches
+            `<article><div>Playwright</div></article>`.
+        has_not_text : Union[Pattern[str], str, None]
+            Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element.
+            When passed a [string], matching is case-insensitive and searches for a substring.
+        has : Union[Locator, None]
+            Narrows down the results of the method to those which contain elements matching this relative locator. For example,
+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in
+            `<article><content><div>Playwright</div></content></article>`. However, looking for `content` that has `article
+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the
+            outer one. For example, `article` that does not have `div` matches `<article><span>Playwright</span></article>`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.

+        For example, this method will find inputs by label \"Username\" and \"Password\" in the following DOM:
+
+        ```html
+        <input aria-label=\"Username\">
+        <label for=\"password-input\">Password:</label>
+        <input id=\"password-input\">
+        ```
+
+        ```py
+        page.get_by_label(\"Username\").fill(\"john\")
+        page.get_by_label(\"Password\").fill(\"secret\")
+        ```
 
         Parameters
         ----------
-        selector : str
-            A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See
-            [working with selectors](./selectors.md#working-with-selectors) for more details.
-        name : str
-            Attribute name to get the value for.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        text : Union[Pattern[str], str]
+            Text to locate the element for.
+        exact : Union[bool, None]
+            Whether to find an exact match: case-sensitive and whole-string. Default to false. Ignored when locating by a
+            regular expression. Note that exact match still trims whitespace.

+        **Details**
+
+        Matching by text always normalizes whitespace, even with exact match. For example, it turns multiple spaces into
+        one, turns line breaks into spaces and ignores leading and trailing whitespace.
+
+        Input elements of the type `button` and `submit` are matched by their `value` instead of the text content. For
+        example, locating by text `\"Log in\"` matches `<input type=button value=\"Log in\">`.

         Parameters
         ----------
-        expression : str
-            Function to be evaluated in browser context
-        force_expr : bool
-            Whether to treat given expression as JavaScript evaluate expression, even though it looks like an arrow function
-        arg : Union[Any, NoneType]
-            Optional argument to pass to `pageFunction`
-        timeout : Union[float, NoneType]
-            maximum time to wait for in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default
-            value can be changed by using the `browser_context.set_default_timeout()`.
-        polling : Union["raf", float, NoneType]
-            If `polling` is `'raf'`, then `pageFunction` is constantly executed in `requestAnimationFrame` callback. If `polling` is
-            a number, then it is treated as an interval in milliseconds at which the function would be executed. Defaults to `raf`.
+        text : Union[Pattern[str], str]
+            Text to locate the element for.
+        exact : Union[bool, None]
+            Whether to find an exact match: case-sensitive and whole-string. Default to false. Ignored when locating by a
+            regular expression. Note that exact match still trims whitespace.

+        `Delete`, `Escape`, `ArrowDown`, `End`, `Enter`, `Home`, `Insert`, `PageDown`, `PageUp`, `ArrowRight`, `ArrowUp`,
+        etc.
+
+        Following modification shortcuts are also supported: `Shift`, `Control`, `Alt`, `Meta`, `ShiftLeft`,
+        `ControlOrMeta`. `ControlOrMeta` resolves to `Control` on Windows and Linux and to `Meta` on macOS.
+
+        Holding down `Shift` will type the text that corresponds to the `key` in the upper case.
+
+        If `key` is a single character, it is case-sensitive, so the values `a` and `A` will generate different respective
+        texts.
+
+        Shortcuts such as `key: \"Control+o\"`, `key: \"Control++` or `key: \"Control+Shift+T\"` are supported as well. When
+        specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.
+
+        Parameters
+        ----------
+        selector : str
+            A selector to search for an element. If there are multiple elements satisfying the selector, the first will be
+            used.
+        key : str
+            Name of the key to press or a character to generate, such as `ArrowLeft` or `a`.
+        delay : Union[float, None]
+            Time to wait between `keydown` and `keyup` in milliseconds. Defaults to 0.
+        strict : Union[bool, None]
+            When true, the call requires selector to resolve to a single element. If given selector resolves to more than one
+            element, the call throws an exception.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        no_wait_after : Union[bool, None]
+            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You
+            can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as

+            passed a [string], matching is case-insensitive and searches for a substring. For example, `"Playwright"` matches
+            `<article><div>Playwright</div></article>`.
+        has_not_text : Union[Pattern[str], str, None]
+            Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element.
+            When passed a [string], matching is case-insensitive and searches for a substring.
+        has : Union[Locator, None]
+            Narrows down the results of the method to those which contain elements matching this relative locator. For example,
+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in
+            `<article><content><div>Playwright</div></content></article>`. However, looking for `content` that has `article
+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the
+            outer one. For example, `article` that does not have `div` matches `<article><span>Playwright</span></article>`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.

+        include_hidden : Union[bool, None]
+            Option that controls whether hidden elements are matched. By default, only non-hidden elements, as

+
+        Routing provides the capability to modify network requests that are made by a page.
+
+        Once routing is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or
+        aborted.
+
+        **NOTE** The handler will only be called for the first url if the response is a redirect.
+
+        **NOTE** `page.route()` will not intercept requests intercepted by Service Worker. See
+        [this](https://github.com/microsoft/playwright/issues/1090) issue. We recommend disabling Service Workers when
+        using request interception by setting `serviceWorkers` to `'block'`.
+
+        **NOTE** `page.route()` will not intercept the first request of a popup page. Use
+        `browser_context.route()` instead.
+
+        **Usage**
+
+        An example of a naive handler that aborts all image requests:
+
+        ```py
+        page = browser.new_page()
+        page.route(\"**/*.{png,jpg,jpeg}\", lambda route: route.abort())
+        page.goto(\"https://example.com\")
+        browser.close()
+        ```
+
+        or the same snippet using a regex pattern instead:
+
+        ```py
+        page = browser.new_page()
+        page.route(re.compile(r\"(\\.png$)|(\\.jpg$)\"), lambda route: route.abort())
+        page.goto(\"https://example.com\")
+        browser.close()
+        ```
+
+        It is possible to examine the request to decide the route action. For example, mocking all requests that contain
+        some post data, and leaving all other requests as is:
+
+        ```py
+        def handle_route(route: Route):
+          if (\"my-string\" in route.request.post_data):

+            route.continue_()
+        page.route(\"/api/**\", handle_route)
+        ```
+
+        Page routes take precedence over browser context routes (set up with `browser_context.route()`) when request
+        matches both handlers.
+
+        To remove a route with its handler you can use `page.unroute()`.

+        method before navigating the page.
+
+        **Usage**
+
+        Below is an example of a simple mock that responds to a single message. See `WebSocketRoute` for more details and
+        examples.
+
+        ```py
+        def message_handler(ws: WebSocketRoute, message: Union[str, bytes]):
+          if message == \"request\":
+            ws.send(\"response\")

+          ws.on_message(lambda message: message_handler(ws, message))
+
+        page.route_web_socket(\"/ws\", handler)
+        ```
+
+        Parameters
+        ----------
+        url : Union[Callable[[str], bool], Pattern[str], str]
+            Only WebSockets with the url matching this pattern will be routed. A string pattern can be relative to the
+            `baseURL` context option.

+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        type : Union["jpeg", "png", None]
+            Specify screenshot type, defaults to `png`.
+        path : Union[pathlib.Path, str, None]
+            The file path to save the image to. The screenshot type will be inferred from file extension. If `path` is a
+            relative path, then it is resolved relative to the current working directory. If no path is provided, the image
+            won't be saved to the disk.
+        quality : Union[int, None]
+            The quality of the image, between 0-100. Not applicable to `png` images.
+        omit_background : Union[bool, None]
+            Hides default white background and allows capturing screenshots with transparency. Not applicable to `jpeg` images.
+            Defaults to `false`.
+        full_page : Union[bool, None]
+            When true, takes a screenshot of the full scrollable page, instead of the currently visible viewport. Defaults to
+            `false`.
+        clip : Union[{x: float, y: float, width: float, height: float}, None]
+            An object which specifies clipping of the resulting image.
+        animations : Union["allow", "disabled", None]
+            When set to `"disabled"`, stops CSS animations, CSS transitions and Web Animations. Animations get different
+            treatment depending on their duration:
+            - finite animations are fast-forwarded to completion, so they'll fire `transitionend` event.
+            - infinite animations are canceled to initial state, and then played over after the screenshot.
+
+            Defaults to `"allow"` that leaves animations untouched.
+        caret : Union["hide", "initial", None]
+            When set to `"hide"`, screenshot will hide text caret. When set to `"initial"`, text caret behavior will not be
+            changed.  Defaults to `"hide"`.
+        scale : Union["css", "device", None]
+            When set to `"css"`, screenshot will have a single pixel per each css pixel on the page. For high-dpi devices, this
+            will keep screenshots small. Using `"device"` option will produce a single pixel per each device pixel, so
+            screenshots of high-dpi devices will be twice as large or even larger.
+
+            Defaults to `"device"`.
+        mask : Union[Sequence[Locator], None]
+            Specify locators that should be masked when the screenshot is taken. Masked elements will be overlaid with a pink
+            box `#FF00FF` (customized by `maskColor`) that completely covers its bounding box. The mask is also applied to
+            invisible elements, see [Matching only visible elements](../locators.md#matching-only-visible-elements) to disable
+            that.
+        mask_color : Union[str, None]
+            Specify the color of the overlay box for masked elements, in
+            [CSS color format](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value). Default color is pink `#FF00FF`.
+        style : Union[str, None]
+            Text of the stylesheet to apply while making the screenshot. This is where you can hide dynamic elements, make
+            elements invisible or change their properties to help you creating repeatable screenshots. This stylesheet pierces
+            the Shadow DOM and applies to the inner frames.

+
+        This method taps an element matching `selector` by performing the following steps:

+        1. Wait for [actionability](https://playwright.dev/python/docs/actionability) checks on the matched element, unless `force` option is set. If
+           the element is detached during the checks, the whole action is retried.
+        1. Scroll the element into view if needed.
+        1. Use `page.touchscreen` to tap the center of the element, or the specified `position`.
+
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.

+
+        The method returns an element locator that can be used to perform actions on this page / frame. Locator is resolved

+        performed on different DOM elements. That would happen if the DOM structure between those actions has changed.
+
+        [Learn more about locators](https://playwright.dev/python/docs/locators).
+
+        Parameters
+        ----------
+        selector : str
+            A selector to use when resolving DOM element.
+        has_text : Union[Pattern[str], str, None]
+            Matches elements containing specified text somewhere inside, possibly in a child or a descendant element. When
+            passed a [string], matching is case-insensitive and searches for a substring. For example, `"Playwright"` matches
+            `<article><div>Playwright</div></article>`.
+        has_not_text : Union[Pattern[str], str, None]
+            Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element.
+            When passed a [string], matching is case-insensitive and searches for a substring.
+        has : Union[Locator, None]
+            Narrows down the results of the method to those which contain elements matching this relative locator. For example,
+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in
+            `<article><content><div>Playwright</div></content></article>`. However, looking for `content` that has `article
+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the
+            outer one. For example, `article` that does not have `div` matches `<article><span>Playwright</span></article>`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.

+
+        **Usage**
+
+        Consider the following DOM structure.
+

+
+        Role selector **does not replace** accessibility audits and conformance tests, but rather gives early feedback
+        about the ARIA guidelines.
+
+        Many html elements have an implicitly [defined role](https://w3c.github.io/html-aam/#html-element-role-mappings)
+        that is recognized by the role selector. You can find all the
+        [supported roles here](https://www.w3.org/TR/wai-aria-1.2/#role_definitions). ARIA guidelines **do not recommend**
+        duplicating implicit roles and attributes by setting `role` and/or `aria-*` attributes to default values.

+            Required aria role.
+        checked : Union[bool, None]
+            An attribute that is usually set by `aria-checked` or native `<input type=checkbox>` controls.
+
+            Learn more about [`aria-checked`](https://www.w3.org/TR/wai-aria-1.2/#aria-checked).
+        disabled : Union[bool, None]
+            An attribute that is usually set by `aria-disabled` or `disabled`.
+
+            **NOTE** Unlike most other attributes, `disabled` is inherited through the DOM hierarchy. Learn more about
+            [`aria-disabled`](https://www.w3.org/TR/wai-aria-1.2/#aria-disabled).
+
+        expanded : Union[bool, None]
+            An attribute that is usually set by `aria-expanded`.
+
+            Learn more about [`aria-expanded`](https://www.w3.org/TR/wai-aria-1.2/#aria-expanded).
+        include_hidden : Union[bool, None]
+            Option that controls whether hidden elements are matched. By default, only non-hidden elements, as
+            [defined by ARIA](https://www.w3.org/TR/wai-aria-1.2/#tree_exclusion), are matched by role selector.
+
+            Learn more about [`aria-hidden`](https://www.w3.org/TR/wai-aria-1.2/#aria-hidden).
+        level : Union[int, None]
+            A number attribute that is usually present for roles `heading`, `listitem`, `row`, `treeitem`, with default values
+            for `<h1>-<h6>` elements.
+
+            Learn more about [`aria-level`](https://www.w3.org/TR/wai-aria-1.2/#aria-level).
+        name : Union[Pattern[str], str, None]
+            Option to match the [accessible name](https://w3c.github.io/accname/#dfn-accessible-name). By default, matching is
+            case-insensitive and searches for a substring, use `exact` to control this behavior.
+
+            Learn more about [accessible name](https://w3c.github.io/accname/#dfn-accessible-name).
+        pressed : Union[bool, None]
+            An attribute that is usually set by `aria-pressed`.
+
+            Learn more about [`aria-pressed`](https://www.w3.org/TR/wai-aria-1.2/#aria-pressed).
+        selected : Union[bool, None]

+
+        **Details**
+
+        Matching by text always normalizes whitespace, even with exact match. For example, it turns multiple spaces into
+        one, turns line breaks into spaces and ignores leading and trailing whitespace.
+
+        Input elements of the type `button` and `submit` are matched by their `value` instead of the text content. For

+
+        This method hovers over an element matching `selector` by performing the following steps:
+        1. Find an element matching `selector`. If there is none, wait until a matching element is attached to the DOM.
+        1. Wait for [actionability](https://playwright.dev/python/docs/actionability) checks on the matched element, unless `force` option is set. If
+           the element is detached during the checks, the whole action is retried.
+        1. Scroll the element into view if needed.
+        1. Use `page.mouse` to hover over the center of the element, or the specified `position`.
+
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.
+        Passing zero timeout disables this.
+
+        Parameters
+        ----------
+        selector : str
+            A selector to search for an element. If there are multiple elements satisfying the selector, the first will be
+            used.
+        modifiers : Union[Sequence[Union["Alt", "Control", "ControlOrMeta", "Meta", "Shift"]], None]
+            Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores
+            current modifiers back. If not specified, currently pressed modifiers are used. "ControlOrMeta" resolves to
+            "Control" on Windows and Linux and to "Meta" on macOS.
+        position : Union[{x: float, y: float}, None]
+            A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of
+            the element.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        no_wait_after : Union[bool, None]
+            This option has no effect.
+            Deprecated: This option has no effect.
+        force : Union[bool, None]

+        strict : Union[bool, None]
+            When true, the call requires selector to resolve to a single element. If given selector resolves to more than one

+            When set, this method only performs the [actionability](../actionability.md) checks and skips the action. Defaults
+            to `false`. Useful to wait until the element is ready for the action without performing it. Note that keyboard
+            `modifiers` will be pressed regardless of `trial` to allow testing elements which are only visible when those keys
+            are pressed.

+        [here](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values). Examples of the keys are:
+
+        `F1` - `F12`, `Digit0`- `Digit9`, `KeyA`- `KeyZ`, `Backquote`, `Minus`, `Equal`, `Backslash`, `Backspace`, `Tab`,
+        `Delete`, `Escape`, `ArrowDown`, `End`, `Enter`, `Home`, `Insert`, `PageDown`, `PageUp`, `ArrowRight`, `ArrowUp`,
+        etc.
+
+        Following modification shortcuts are also supported: `Shift`, `Control`, `Alt`, `Meta`, `ShiftLeft`,
+        `ControlOrMeta`. `ControlOrMeta` resolves to `Control` on Windows and Linux and to `Meta` on macOS.
+
+        Holding down `Shift` will type the text that corresponds to the `key` in the upper case.
+
+        If `key` is a single character, it is case-sensitive, so the values `a` and `A` will generate different respective
+        texts.
+
+        Shortcuts such as `key: \"Control+o\"`, `key: \"Control++` or `key: \"Control+Shift+T\"` are supported as well. When
+        specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.
+
+        **Usage**
+
+        ```py
+        page = browser.new_page()
+        page.goto(\"https://keycode.info\")
+        page.press(\"body\", \"A\")
+        page.screenshot(path=\"a.png\")
+        page.press(\"body\", \"ArrowLeft\")
+        page.screenshot(path=\"arrow_left.png\")
+        page.press(\"body\", \"Shift+O\")
+        page.screenshot(path=\"o.png\")
+        browser.close()
+        ```
+
+        Parameters
+        ----------
+        selector : str
+            A selector to search for an element. If there are multiple elements satisfying the selector, the first will be
+            used.
+        key : str
+            Name of the key to press or a character to generate, such as `ArrowLeft` or `a`.
+        delay : Union[float, None]
+            Time to wait between `keydown` and `keyup` in milliseconds. Defaults to 0.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        no_wait_after : Union[bool, None]
+            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You
+            can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as
+            navigating to inaccessible pages. Defaults to `false`.
+            Deprecated: This option will default to `true` in the future.
+        strict : Union[bool, None]
+            When true, the call requires selector to resolve to a single element. If given selector resolves to more than one
+            element, the call throws an exception.

+
+        **Usage**
+
+        This resolves when the page navigates to a new URL or reloads. It is useful for when you run code which will
+        indirectly cause the page to navigate. e.g. The click target has an `onclick` handler that triggers navigation from
+        a `setTimeout`. Consider this example:
+
+        ```py
+        with page.expect_navigation():
+            # This action triggers the navigation after a timeout.
+            page.get_by_text(\"Navigate after timeout\").click()
+        # Resolves after navigation has finished
+        ```
+
+        **NOTE** Usage of the [History API](https://developer.mozilla.org/en-US/docs/Web/API/History_API) to change the URL
+        is considered a navigation.

+        Parameters
+        ----------
+        url : Union[Callable[[str], bool], Pattern[str], str, None]
+            A glob pattern, regex pattern or predicate receiving [URL] to match while waiting for the navigation. Note that if
+            the parameter is a string without wildcard characters, the method will wait for navigation to URL that is exactly
+            equal to the string.
+        wait_until : Union["commit", "domcontentloaded", "load", "networkidle", None]
+            When to consider operation succeeded, defaults to `load`. Events can be either:
+            - `'domcontentloaded'` - consider operation to be finished when the `DOMContentLoaded` event is fired.
+            - `'load'` - consider operation to be finished when the `load` event is fired.
+            - `'networkidle'` - **DISCOURAGED** consider operation to be finished when there are no network connections for
+              at least `500` ms. Don't use this method for testing, rely on web assertions to assess readiness instead.
+            - `'commit'` - consider operation to be finished when network response is received and the document started
+              loading.
+        timeout : Union[float, None]
+            Maximum operation time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can

+        """Page.add_locator_handler
+
+        When testing a web page, sometimes unexpected overlays like a \"Sign up\" dialog appear and block actions you want to
+        automate, e.g. clicking a button. These overlays don't always show up in the same way or at the same time, making
+        them tricky to handle in automated tests.
+
+        This method lets you set up a special function, called a handler, that activates when it detects that overlay is
+        visible. The handler's job is to remove the overlay, allowing your test to continue as if the overlay wasn't there.
+
+        Things to keep in mind:
+        - When an overlay is shown predictably, we recommend explicitly waiting for it in your test and dismissing it as
+          a part of your normal test flow, instead of using `page.add_locator_handler()`.
+        - Playwright checks for the overlay every time before executing or retrying an action that requires an
+          [actionability check](https://playwright.dev/python/docs/actionability), or before performing an auto-waiting assertion check. When overlay
+          is visible, Playwright calls the handler first, and then proceeds with the action/assertion. Note that the
+          handler is only called when you perform an action/assertion - if the overlay becomes visible but you don't
+          perform any actions, the handler will not be triggered.
+        - After executing the handler, Playwright will ensure that overlay that triggered the handler is not visible
+          anymore. You can opt-out of this behavior with `noWaitAfter`.
+        - The execution time of the handler counts towards the timeout of the action/assertion that executed the handler.
+          If your handler takes too long, it might cause timeouts.
+        - You can register multiple handlers. However, only a single handler will be running at a time. Make sure the
+          actions within a handler don't depend on another handler.
+
+        **NOTE** Running the handler will alter your page state mid-test. For example it will change the currently focused
+        element and move the mouse. Make sure that actions that run after the handler are self-contained and do not rely on
+        the focus and mouse state being unchanged.
+
+        For example, consider a test that calls `locator.focus()` followed by `keyboard.press()`. If your
+        handler clicks a button between these two actions, the focused element most likely will be wrong, and key press
+        will happen on the unexpected element. Use `locator.press()` instead to avoid this problem.
+
+        Another example is a series of mouse actions, where `mouse.move()` is followed by `mouse.down()`.
+        Again, when the handler runs between these two actions, the mouse position will be wrong during the mouse down.
+        Prefer self-contained actions like `locator.click()` that do not rely on the state being unchanged by a
+        handler.
+
+        **Usage**
+
+        An example that closes a \"Sign up to the newsletter\" dialog when it appears:
+
+        ```py
+        # Setup the handler.
+        def handler():
+          await page.get_by_role(\"button\", name=\"No thanks\").click()
+        await page.add_locator_handler(page.get_by_text(\"Sign up to the newsletter\"), handler)
+
+        # Write the test as usual.
+        await page.goto(\"https://example.com\")
+        await page.get_by_role(\"button\", name=\"Start here\").click()
+        ```
+
+        An example that skips the \"Confirm your security details\" page when it is shown:
+
+        ```py
+        # Setup the handler.
+        def handler():
+          await page.get_by_role(\"button\", name=\"Remind me later\").click()
+        await page.add_locator_handler(page.get_by_text(\"Confirm your security details\"), handler)
+
+        # Write the test as usual.
+        await page.goto(\"https://example.com\")
+        await page.get_by_role(\"button\", name=\"Start here\").click()
+        ```
+
+        An example with a custom callback on every actionability check. It uses a `<body>` locator that is always visible,
+        so the handler is called before every actionability check. It is important to specify `noWaitAfter`, because the
+        handler does not hide the `<body>` element.
+
+        ```py
+        # Setup the handler.
+        def handler():
+          await page.evaluate(\"window.removeObstructionsForTestIfNeeded()\")
+        await page.add_locator_handler(page.locator(\"body\"), handler, no_wait_after=True)
+
+        # Write the test as usual.
+        await page.goto(\"https://example.com\")
+        await page.get_by_role(\"button\", name=\"Start here\").click()
+        ```
+
+        Handler takes the original locator as an argument. You can also automatically remove the handler after a number of
+        invocations by setting `times`:
+
+        ```py
+        def handler(locator):
+          await locator.click()
+        await page.add_locator_handler(page.get_by_label(\"Close\"), handler, times=1)
+        ```
+
+        Parameters
+        ----------
+        locator : Locator
+            Locator that triggers the handler.
+        handler : Union[Callable[[Locator], Any], Callable[[], Any]]
+            Function that should be run once `locator` appears. This function should get rid of the element that blocks actions
+            like click.
+        no_wait_after : Union[bool, None]
+            By default, after calling the handler Playwright will wait until the overlay becomes hidden, and only then
+            Playwright will continue with the action/assertion that triggered the handler. This option allows to opt-out of
+            this behavior, so that overlay can stay visible after the handler has run.
+        times : Union[int, None]
+            Specifies the maximum number of times this handler should be called. Unlimited by default.

+
+        Routing provides the capability to modify network requests that are made by any page in the browser context. Once
+        route is enabled, every request matching the url pattern will stall unless it's continued, fulfilled or aborted.
+
+        **NOTE** `browser_context.route()` will not intercept requests intercepted by Service Worker. See
+        [this](https://github.com/microsoft/playwright/issues/1090) issue. We recommend disabling Service Workers when
+        using request interception by setting `serviceWorkers` to `'block'`.
+
+        **Usage**
+
+        An example of a naive handler that aborts all image requests:
+
+        ```py
+        context = browser.new_context()
+        page = context.new_page()
+        context.route(\"**/*.{png,jpg,jpeg}\", lambda route: route.abort())
+        page.goto(\"https://example.com\")
+        browser.close()
+        ```
+
+        or the same snippet using a regex pattern instead:
+
+        ```py
+        context = browser.new_context()
+        page = context.new_page()
+        context.route(re.compile(r\"(\\.png$)|(\\.jpg$)\"), lambda route: route.abort())
+        page = await context.new_page()
+        page = context.new_page()
+        page.goto(\"https://example.com\")
+        browser.close()
+        ```
+
+        It is possible to examine the request to decide the route action. For example, mocking all requests that contain
+        some post data, and leaving all other requests as is:
+
+        ```py
+        def handle_route(route: Route):
+          if (\"my-string\" in route.request.post_data):
+            route.fulfill(body=\"mocked-data\")
+          else:
+            route.continue_()
+        context.route(\"/api/**\", handle_route)
+        ```
+
+        Page routes (set up with `page.route()`) take precedence over browser context routes when request matches
+        both handlers.
+
+        To remove a route with its handler you can use `browser_context.unroute()`.
+
+        **NOTE** Enabling routing disables http cache.

+        accept_downloads : Union[bool, None]
+            Whether to automatically download all the attachments. Defaults to `true` where all the downloads are accepted.
+        proxy : Union[{server: str, bypass: Union[str, None], username: Union[str, None], password: Union[str, None]}, None]
+            Network proxy settings to use with this context. Defaults to none.
+        record_har_path : Union[pathlib.Path, str, None]
+            Enables [HAR](http://www.softwareishard.com/blog/har-12-spec) recording for all pages into the specified HAR file
+            on the filesystem. If not specified, the HAR is not recorded. Make sure to call `browser_context.close()`
+            for the HAR to be saved.
+        record_har_omit_content : Union[bool, None]
+            Optional setting to control whether to omit request content from the HAR. Defaults to `false`.
+        record_video_dir : Union[pathlib.Path, str, None]
+            Enables video recording for all pages into the specified directory. If not specified videos are not recorded. Make
+            sure to call `browser_context.close()` for videos to be saved.
+        record_video_size : Union[{width: int, height: int}, None]
+            Dimensions of the recorded videos. If not specified the size will be equal to `viewport` scaled down to fit into
+            800x800. If `viewport` is not configured explicitly the video size defaults to 800x450. Actual picture of each page
+            will be scaled down if necessary to fit the specified size.
+        storage_state : Union[pathlib.Path, str, {cookies: Sequence[{name: str, value: str, domain: str, path: str, expires: float, httpOnly: bool, secure: bool, sameSite: Union["Lax", "None", "Strict"]}], origins: Sequence[{origin: str, localStorage: Sequence[{name: str, value: str}]}]}, None]
+            Learn more about [storage state and auth](../auth.md).
+
+            Populates context with given storage state. This option can be used to initialize context with logged-in
+            information obtained via `browser_context.storage_state()`.
+        base_url : Union[str, None]
+            When using `page.goto()`, `page.route()`, `page.wait_for_url()`,
+            `page.expect_request()`, or `page.expect_response()` it takes the base URL in consideration by
+            using the [`URL()`](https://developer.mozilla.org/en-US/docs/Web/API/URL/URL) constructor for building the
+            corresponding URL. Unset by default. Examples:
+            - baseURL: `http://localhost:3000` and navigating to `/bar.html` results in `http://localhost:3000/bar.html`
+            - baseURL: `http://localhost:3000/foo/` and navigating to `./bar.html` results in
+              `http://localhost:3000/foo/bar.html`
+            - baseURL: `http://localhost:3000/foo` (without trailing slash) and navigating to `./bar.html` results in
+              `http://localhost:3000/bar.html`
+        strict_selectors : Union[bool, None]
+            If set to true, enables strict selectors mode for this context. In the strict selectors mode all operations on
+            selectors that imply single target DOM element will throw when more than one element matches the selector. This
+            option does not affect any Locator APIs (Locators are always strict). Defaults to `false`. See `Locator` to learn

+        """Browser.new_page
+
+        Creates a new page in a new browser context. Closing this page will close the context as well.
+
+        This is a convenience API that should only be used for the single-page scenarios and short snippets. Production
+        code and testing frameworks should explicitly create `browser.new_context()` followed by the
+        `browser_context.new_page()` to control their exact life times.

+            Emulates `'prefers-reduced-motion'` media feature, supported values are `'reduce'`, `'no-preference'`. See
+            `page.emulate_media()` for more details. Passing `'null'` resets emulation to system defaults. Defaults to
+            `'no-preference'`.
+        accept_downloads : Union[bool, None]
+            Whether to automatically download all the attachments. Defaults to `true` where all the downloads are accepted.
+        proxy : Union[{server: str, bypass: Union[str, None], username: Union[str, None], password: Union[str, None]}, None]
+            Network proxy settings to use with this context. Defaults to none.
+        record_har_path : Union[pathlib.Path, str, None]
+            Enables [HAR](http://www.softwareishard.com/blog/har-12-spec) recording for all pages into the specified HAR file
+            on the filesystem. If not specified, the HAR is not recorded. Make sure to call `browser_context.close()`
+            for the HAR to be saved.
+        record_har_omit_content : Union[bool, None]
+            Optional setting to control whether to omit request content from the HAR. Defaults to `false`.
+        record_video_dir : Union[pathlib.Path, str, None]
+            Enables video recording for all pages into the specified directory. If not specified videos are not recorded. Make
+            sure to call `browser_context.close()` for videos to be saved.
+        record_video_size : Union[{width: int, height: int}, None]
+            Dimensions of the recorded videos. If not specified the size will be equal to `viewport` scaled down to fit into
+            800x800. If `viewport` is not configured explicitly the video size defaults to 800x450. Actual picture of each page
+            will be scaled down if necessary to fit the specified size.
+        storage_state : Union[pathlib.Path, str, {cookies: Sequence[{name: str, value: str, domain: str, path: str, expires: float, httpOnly: bool, secure: bool, sameSite: Union["Lax", "None", "Strict"]}], origins: Sequence[{origin: str, localStorage: Sequence[{name: str, value: str}]}]}, None]
+            Learn more about [storage state and auth](../auth.md).
+
+            Populates context with given storage state. This option can be used to initialize context with logged-in
+            information obtained via `browser_context.storage_state()`.
+        base_url : Union[str, None]
+            When using `page.goto()`, `page.route()`, `page.wait_for_url()`,
+            `page.expect_request()`, or `page.expect_response()` it takes the base URL in consideration by
+            using the [`URL()`](https://developer.mozilla.org/en-US/docs/Web/API/URL/URL) constructor for building the
+            corresponding URL. Unset by default. Examples:
+            - baseURL: `http://localhost:3000` and navigating to `/bar.html` results in `http://localhost:3000/bar.html`
+            - baseURL: `http://localhost:3000/foo/` and navigating to `./bar.html` results in
+              `http://localhost:3000/foo/bar.html`
+            - baseURL: `http://localhost:3000/foo` (without trailing slash) and navigating to `./bar.html` results in
+              `http://localhost:3000/bar.html`
+        strict_selectors : Union[bool, None]
+            If set to true, enables strict selectors mode for this context. In the strict selectors mode all operations on
+            selectors that imply single target DOM element will throw when more than one element matches the selector. This
+            option does not affect any Locator APIs (Locators are always strict). Defaults to `false`. See `Locator` to learn
+            more about the strict mode.
+        service_workers : Union["allow", "block", None]
+            Whether to allow sites to register Service workers. Defaults to `'allow'`.
+            - `'allow'`: [Service Workers](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API) can be
+              registered.
+            - `'block'`: Playwright will block all registration of Service Workers.
+        record_har_url_filter : Union[Pattern[str], str, None]
+        record_har_mode : Union["full", "minimal", None]
+            When set to `minimal`, only record information necessary for routing from HAR. This omits sizes, timing, page,
+            cookies, security and other types of HAR information that are not used when replaying from HAR. Defaults to `full`.
+        record_har_content : Union["attach", "embed", "omit", None]

+
+        Parameters
+        ----------
+        executable_path : Union[pathlib.Path, str, None]
+            Path to a browser executable to run instead of the bundled one. If `executablePath` is a relative path, then it is
+            resolved relative to the current working directory. Note that Playwright only works with the bundled Chromium,
+            Firefox or WebKit, use at your own risk.
+        channel : Union[str, None]
+            Browser distribution channel.
+
+            Use "chromium" to [opt in to new headless mode](../browsers.md#chromium-new-headless-mode).
+
+            Use "chrome", "chrome-beta", "chrome-dev", "chrome-canary", "msedge", "msedge-beta", "msedge-dev", or
+            "msedge-canary" to use branded [Google Chrome and Microsoft Edge](../browsers.md#google-chrome--microsoft-edge).
+        args : Union[Sequence[str], None]
+            **NOTE** Use custom browser args at your own risk, as some of them may break Playwright functionality.
+
+            Additional arguments to pass to the browser instance. The list of Chromium flags can be found
+            [here](https://peter.sh/experiments/chromium-command-line-switches/).
+        ignore_default_args : Union[Sequence[str], bool, None]
+            If `true`, Playwright does not pass its own configurations args and only uses the ones from `args`. If an array is
+            given, then filters out the given default arguments. Dangerous option; use with care. Defaults to `false`.
+        handle_sigint : Union[bool, None]
+            Close the browser process on Ctrl-C. Defaults to `true`.
+        handle_sigterm : Union[bool, None]
+            Close the browser process on SIGTERM. Defaults to `true`.
+        handle_sighup : Union[bool, None]
+            Close the browser process on SIGHUP. Defaults to `true`.
+        timeout : Union[float, None]
+            Maximum time in milliseconds to wait for the browser instance to start. Defaults to `30000` (30 seconds). Pass `0`
+            to disable timeout.
+        env : Union[Dict[str, Union[bool, float, str]], None]
+            Specify environment variables that will be visible to the browser. Defaults to `process.env`.
+        headless : Union[bool, None]
+            Whether to run browser in headless mode. More details for
+            [Chromium](https://developers.google.com/web/updates/2017/04/headless-chrome) and
+            [Firefox](https://hacks.mozilla.org/2017/12/using-headless-mode-in-firefox/). Defaults to `true` unless the
+            `devtools` option is `true`.
+        devtools : Union[bool, None]
+            **Chromium-only** Whether to auto-open a Developer Tools panel for each tab. If this option is `true`, the
+            `headless` option will be set `false`.
+            Deprecated: Use [debugging tools](../debug.md) instead.
+        proxy : Union[{server: str, bypass: Union[str, None], username: Union[str, None], password: Union[str, None]}, None]
+            Network proxy settings.
+        downloads_path : Union[pathlib.Path, str, None]
+            If specified, accepted downloads are downloaded into this directory. Otherwise, temporary directory is created and
+            is deleted when browser is closed. In either case, the downloads are deleted when the browser context they were
+            created in is closed.
+        slow_mo : Union[float, None]
+            Slows down Playwright operations by the specified amount of milliseconds. Useful so that you can see what is going
+            on.
+        traces_dir : Union[pathlib.Path, str, None]
+            If specified, traces are saved into this directory.
+        chromium_sandbox : Union[bool, None]
+            Enable Chromium sandboxing. Defaults to `false`.
+        firefox_user_prefs : Union[Dict[str, Union[bool, float, str]], None]
+            Firefox user preferences. Learn more about the Firefox user preferences at
+            [`about:config`](https://support.mozilla.org/en-US/kb/about-config-editor-firefox).
+
+            You can also provide a path to a custom [`policies.json` file](https://mozilla.github.io/policy-templates/) via
+            `PLAYWRIGHT_FIREFOX_POLICIES_JSON` environment variable.

+            [`about:config`](https://support.mozilla.org/en-US/kb/about-config-editor-firefox).
+
+            You can also provide a path to a custom [`policies.json` file](https://mozilla.github.io/policy-templates/) via
+            `PLAYWRIGHT_FIREFOX_POLICIES_JSON` environment variable.
+        record_har_path : Union[pathlib.Path, str, None]
+            Enables [HAR](http://www.softwareishard.com/blog/har-12-spec) recording for all pages into the specified HAR file
+            on the filesystem. If not specified, the HAR is not recorded. Make sure to call `browser_context.close()`
+            for the HAR to be saved.
+        record_har_omit_content : Union[bool, None]
+            Optional setting to control whether to omit request content from the HAR. Defaults to `false`.
+        record_video_dir : Union[pathlib.Path, str, None]
+            Enables video recording for all pages into the specified directory. If not specified videos are not recorded. Make
+            sure to call `browser_context.close()` for videos to be saved.
+        record_video_size : Union[{width: int, height: int}, None]
+            Dimensions of the recorded videos. If not specified the size will be equal to `viewport` scaled down to fit into
+            800x800. If `viewport` is not configured explicitly the video size defaults to 800x450. Actual picture of each page
+            will be scaled down if necessary to fit the specified size.
+        base_url : Union[str, None]
+            When using `page.goto()`, `page.route()`, `page.wait_for_url()`,
+            `page.expect_request()`, or `page.expect_response()` it takes the base URL in consideration by
+            using the [`URL()`](https://developer.mozilla.org/en-US/docs/Web/API/URL/URL) constructor for building the
+            corresponding URL. Unset by default. Examples:
+            - baseURL: `http://localhost:3000` and navigating to `/bar.html` results in `http://localhost:3000/bar.html`
+            - baseURL: `http://localhost:3000/foo/` and navigating to `./bar.html` results in
+              `http://localhost:3000/foo/bar.html`
+            - baseURL: `http://localhost:3000/foo` (without trailing slash) and navigating to `./bar.html` results in
+              `http://localhost:3000/bar.html`
+        strict_selectors : Union[bool, None]
+            If set to true, enables strict selectors mode for this context. In the strict selectors mode all operations on
+            selectors that imply single target DOM element will throw when more than one element matches the selector. This
+            option does not affect any Locator APIs (Locators are always strict). Defaults to `false`. See `Locator` to learn
+            more about the strict mode.
+        service_workers : Union["allow", "block", None]
+            Whether to allow sites to register Service workers. Defaults to `'allow'`.
+            - `'allow'`: [Service Workers](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API) can be
+              registered.
+            - `'block'`: Playwright will block all registration of Service Workers.
+        record_har_url_filter : Union[Pattern[str], str, None]
+        record_har_mode : Union["full", "minimal", None]
+            When set to `minimal`, only record information necessary for routing from HAR. This omits sizes, timing, page,
+            cookies, security and other types of HAR information that are not used when replaying from HAR. Defaults to `full`.
+        record_har_content : Union["attach", "embed", "omit", None]
+            Optional setting to control resource content management. If `omit` is specified, content is not persisted. If
+            `attach` is specified, resources are persisted as separate files and all of these files are archived along with the
+            HAR file. Defaults to `embed`, which stores content inline the HAR file as per HAR specification.
+        client_certificates : Union[Sequence[{origin: str, certPath: Union[pathlib.Path, str, None], cert: Union[bytes, None], keyPath: Union[pathlib.Path, str, None], key: Union[bytes, None], pfxPath: Union[pathlib.Path, str, None], pfx: Union[bytes, None], passphrase: Union[str, None]}], None]
+            TLS Client Authentication allows the server to request a client certificate and verify it.
+
+            **Details**
+
+            An array of client certificates to be used. Each certificate object must have either both `certPath` and `keyPath`,
+            a single `pfxPath`, or their corresponding direct value equivalents (`cert` and `key`, or `pfx`). Optionally,
+            `passphrase` property should be provided if the certificate is encrypted. The `origin` property should be provided
+            with an exact match to the request origin that the certificate is valid for.
+
+            **NOTE** When using WebKit on macOS, accessing `localhost` will not pick up client certificates. You can make it
+            work by replacing `localhost` with `local.playwright`.

+            on. Defaults to 0.
+        headers : Union[Dict[str, str], None]
+            Additional HTTP headers to be sent with web socket connect request. Optional.
+        expose_network : Union[str, None]
+            This option exposes network available on the connecting client to the browser being connected to. Consists of a
+            list of rules separated by comma.
+
+            Available rules:
+            1. Hostname pattern, for example: `example.com`, `*.org:99`, `x.*.y.com`, `*foo.org`.
+            1. IP literal, for example: `127.0.0.1`, `0.0.0.0:99`, `[::1]`, `[0:0::1]:99`.
+            1. `<loopback>` that matches local loopback interfaces: `localhost`, `*.localhost`, `127.0.0.1`, `[::1]`.
+
+            Some common examples:
+            1. `"*"` to expose all network.
+            1. `"<loopback>"` to expose localhost network.
+            1. `"*.test.internal-domain,*.staging.internal-domain,<loopback>"` to expose test/staging deployments and
+               localhost.

+
+        Click an element.
+
+        **Details**
+
+        This method clicks the element by performing the following steps:
+        1. Wait for [actionability](https://playwright.dev/python/docs/actionability) checks on the element, unless `force` option is set.
+        1. Scroll the element into view if needed.
+        1. Use `page.mouse` to click in the center of the element, or the specified `position`.
+        1. Wait for initiated navigations to either succeed or fail, unless `noWaitAfter` option is set.
+
+        If the element is detached from the DOM at any moment during the action, this method throws.
+
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.
+        Passing zero timeout disables this.
+
+        **Usage**
+
+        Click a button:
+
+        ```py
+        page.get_by_role(\"button\").click()
+        ```
+
+        Shift-right-click at a specific position on a canvas:

+        modifiers : Union[Sequence[Union["Alt", "Control", "ControlOrMeta", "Meta", "Shift"]], None]
+            Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores
+            current modifiers back. If not specified, currently pressed modifiers are used. "ControlOrMeta" resolves to
+            "Control" on Windows and Linux and to "Meta" on macOS.
+        position : Union[{x: float, y: float}, None]
+            A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of
+            the element.

+            Defaults to `left`.
+        click_count : Union[int, None]
+            defaults to 1. See [UIEvent.detail].
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        force : Union[bool, None]
+            Whether to bypass the [actionability](../actionability.md) checks. Defaults to `false`.
+        no_wait_after : Union[bool, None]
+            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You
+            can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as
+            navigating to inaccessible pages. Defaults to `false`.
+            Deprecated: This option will default to `true` in the future.
+        trial : Union[bool, None]
+            When set, this method only performs the [actionability](../actionability.md) checks and skips the action. Defaults
+            to `false`. Useful to wait until the element is ready for the action without performing it. Note that keyboard
+            `modifiers` will be pressed regardless of `trial` to allow testing elements which are only visible when those keys
+            are pressed.

+        ```
+
+        **Details**
+
+        The snippet above dispatches the `click` event on the element. Regardless of the visibility state of the element,
+        `click` is dispatched. This is equivalent to calling
+        [element.click()](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click).
+
+        Under the hood, it creates an instance of an event based on the given `type`, initializes it with `eventInit`
+        properties and dispatches it on the element. Events are `composed`, `cancelable` and bubble by default.
+
+        Since `eventInit` is event-specific, please refer to the events documentation for the lists of initial properties:
+        - [DeviceMotionEvent](https://developer.mozilla.org/en-US/docs/Web/API/DeviceMotionEvent/DeviceMotionEvent)
+        - [DeviceOrientationEvent](https://developer.mozilla.org/en-US/docs/Web/API/DeviceOrientationEvent/DeviceOrientationEvent)
+        - [DragEvent](https://developer.mozilla.org/en-US/docs/Web/API/DragEvent/DragEvent)
+        - [Event](https://developer.mozilla.org/en-US/docs/Web/API/Event/Event)
+        - [FocusEvent](https://developer.mozilla.org/en-US/docs/Web/API/FocusEvent/FocusEvent)
+        - [KeyboardEvent](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/KeyboardEvent)
+        - [MouseEvent](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/MouseEvent)
+        - [PointerEvent](https://developer.mozilla.org/en-US/docs/Web/API/PointerEvent/PointerEvent)
+        - [TouchEvent](https://developer.mozilla.org/en-US/docs/Web/API/TouchEvent/TouchEvent)
+        - [WheelEvent](https://developer.mozilla.org/en-US/docs/Web/API/WheelEvent/WheelEvent)
+
+        You can also specify `JSHandle` as the property value if you want live objects to be passed into the event:

+        [control](https://developer.mozilla.org/en-US/docs/Web/API/HTMLLabelElement/control), the control will be cleared
+        instead.

+

+
+        Parameters
+        ----------
+        selector_or_locator : Union[Locator, str]
+            A selector or locator to use when resolving DOM element.
+        has_text : Union[Pattern[str], str, None]
+            Matches elements containing specified text somewhere inside, possibly in a child or a descendant element. When
+            passed a [string], matching is case-insensitive and searches for a substring. For example, `"Playwright"` matches
+            `<article><div>Playwright</div></article>`.
+        has_not_text : Union[Pattern[str], str, None]
+            Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element.
+            When passed a [string], matching is case-insensitive and searches for a substring.
+        has : Union[Locator, None]
+            Narrows down the results of the method to those which contain elements matching this relative locator. For example,
+            `article` that has `text=Playwright` matches `<article><div>Playwright</div></article>`.
+
+            Inner locator **must be relative** to the outer locator and is queried starting with the outer locator match, not
+            the document root. For example, you can find `content` that has `div` in
+            `<article><content><div>Playwright</div></content></article>`. However, looking for `content` that has `article
+            div` will fail, because the inner locator must be relative and should not use any elements outside the `content`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.
+        has_not : Union[Locator, None]
+            Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the
+            outer one. For example, `article` that does not have `div` matches `<article><span>Playwright</span></article>`.
+
+            Note that outer and inner locators must belong to the same frame. Inner locator must not contain `FrameLocator`s.

+
+        Input elements of the type `button` and `submit` are matched by their `value` instead of the text content. For

+        Note that when both locators match something, the resulting locator will have multiple matches, potentially causing
+        a [locator strictness](https://playwright.dev/python/docs/locators#strictness) violation.
+
+        **Usage**
+
+        Consider a scenario where you'd like to click on a \"New email\" button, but sometimes a security settings dialog
+        shows up instead. In this case, you can wait for either a \"New email\" button, or a dialog and act accordingly.
+
+        **NOTE** If both \"New email\" button and security dialog appear on screen, the \"or\" locator will match both of them,
+        possibly throwing the [\"strict mode violation\" error](https://playwright.dev/python/docs/locators#strictness). In this case, you can use
+        `locator.first()` to only match one of them.
+
+        ```py
+        new_email = page.get_by_role(\"button\", name=\"New\")
+        dialog = page.get_by_text(\"Confirm security settings\")
+        expect(new_email.or_(dialog).first).to_be_visible()
+        if (dialog.is_visible()):
+          page.get_by_role(\"button\", name=\"Dismiss\").click()

         Parameters
         ----------
-        selector : str
-            A selector to query for. See [working with selectors](./selectors.md#working-with-selectors) for more details.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by

-        state : Union["attached", "detached", "hidden", "visible", NoneType]
-            Defaults to `'visible'`. Can be either:
-            - `'attached'` - wait for element to be present in DOM.
-            - `'detached'` - wait for element to not be present in DOM.
-            - `'visible'` - wait for element to have non-empty bounding box and no `visibility:hidden`. Note that element without
-              any content or with `display:none` has an empty bounding box and is not considered visible.
-            - `'hidden'` - wait for element to be either detached from DOM, or have an empty bounding box or `visibility:hidden`.
-              This is opposite to the `'visible'` option.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can

+
+        Focuses the element, and then uses `keyboard.down()` and `keyboard.up()`.
+
+        `key` can specify the intended
+        [keyboardEvent.key](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key) value or a single character
+        to generate the text for. A superset of the `key` values can be found
+        [here](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values). Examples of the keys are:
+
+        `F1` - `F12`, `Digit0`- `Digit9`, `KeyA`- `KeyZ`, `Backquote`, `Minus`, `Equal`, `Backslash`, `Backspace`, `Tab`,
+        `Delete`, `Escape`, `ArrowDown`, `End`, `Enter`, `Home`, `Insert`, `PageDown`, `PageUp`, `ArrowRight`, `ArrowUp`,
+        etc.
+
+        Following modification shortcuts are also supported: `Shift`, `Control`, `Alt`, `Meta`, `ShiftLeft`,
+        `ControlOrMeta`. `ControlOrMeta` resolves to `Control` on Windows and Linux and to `Meta` on macOS.
+
+        Holding down `Shift` will type the text that corresponds to the `key` in the upper case.
+
+        If `key` is a single character, it is case-sensitive, so the values `a` and `A` will generate different respective
+        texts.
+
+        Shortcuts such as `key: \"Control+o\"`, `key: \"Control++` or `key: \"Control+Shift+T\"` are supported as well. When
+        specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.
+
+        Parameters
+        ----------

+
+        This method captures a screenshot of the page, clipped to the size and position of a particular element matching

+
+        Returns the buffer with the captured screenshot.
 
         Parameters
         ----------
-        url : Union[str, NoneType]
-            URL of a script to be added. Optional.
-        path : Union[pathlib.Path, str, NoneType]
-            Path to the JavaScript file to be injected into frame. If `path` is a relative path, then it is resolved relative to the
-            current working directory. Optional.
-        content : Union[str, NoneType]
-            Raw JavaScript content to be injected into frame. Optional.
-        type : Union[str, NoneType]
-            Script type. Use 'module' in order to load a Javascript ES6 module. See
-            [script](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script) for more details. Optional.
+        timeout : Union[float, None]
+            Maximum time in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout. The default value can
+            be changed by using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
+        type : Union["jpeg", "png", None]
+            Specify screenshot type, defaults to `png`.
+        path : Union[pathlib.Path, str, None]
+            The file path to save the image to. The screenshot type will be inferred from file extension. If `path` is a
+            relative path, then it is resolved relative to the current working directory. If no path is provided, the image
+            won't be saved to the disk.
+        quality : Union[int, None]
+            The quality of the image, between 0-100. Not applicable to `png` images.
+        omit_background : Union[bool, None]
+            Hides default white background and allows capturing screenshots with transparency. Not applicable to `jpeg` images.
+            Defaults to `false`.
+        animations : Union["allow", "disabled", None]
+            When set to `"disabled"`, stops CSS animations, CSS transitions and Web Animations. Animations get different
+            treatment depending on their duration:
+            - finite animations are fast-forwarded to completion, so they'll fire `transitionend` event.
+            - infinite animations are canceled to initial state, and then played over after the screenshot.
+
+            Defaults to `"allow"` that leaves animations untouched.
+        caret : Union["hide", "initial", None]
+            When set to `"hide"`, screenshot will hide text caret. When set to `"initial"`, text caret behavior will not be
+            changed.  Defaults to `"hide"`.
+        scale : Union["css", "device", None]
+            When set to `"css"`, screenshot will have a single pixel per each css pixel on the page. For high-dpi devices, this
+            will keep screenshots small. Using `"device"` option will produce a single pixel per each device pixel, so
+            screenshots of high-dpi devices will be twice as large or even larger.
+
+            Defaults to `"device"`.
+        mask : Union[Sequence[Locator], None]
+            Specify locators that should be masked when the screenshot is taken. Masked elements will be overlaid with a pink
+            box `#FF00FF` (customized by `maskColor`) that completely covers its bounding box. The mask is also applied to
+            invisible elements, see [Matching only visible elements](../locators.md#matching-only-visible-elements) to disable
+            that.
+        mask_color : Union[str, None]
+            Specify the color of the overlay box for masked elements, in
+            [CSS color format](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value). Default color is pink `#FF00FF`.
+        style : Union[str, None]
+            Text of the stylesheet to apply while making the screenshot. This is where you can hide dynamic elements, make
+            elements invisible or change their properties to help you creating repeatable screenshots. This stylesheet pierces
+            the Shadow DOM and applies to the inner frames.

-        `page.goto` will not throw an error when any valid HTTP status code is returned by the remote server, including 404 "Not
-        Found" and 500 "Internal Server Error".  The status code for such responses can be retrieved by calling

+        1. Scroll the element into view if needed.
+        1. Use `page.touchscreen` to tap the center of the element, or the specified `position`.
 
-        > **NOTE** `page.goto` either throws an error or returns a main resource response. The only exceptions are navigation to
-        `about:blank` or navigation to the same URL with a different hash, which would succeed and return `null`.
-        > **NOTE** Headless mode doesn't support navigation to a PDF document. See the
-        [upstream issue](https://bugs.chromium.org/p/chromium/issues/detail?id=761295).
+        If the element is detached from the DOM at any moment during the action, this method throws.
 
-        Shortcut for main frame's `frame.goto()`
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.
+        Passing zero timeout disables this.
+
+        **NOTE** `element.tap()` requires that the `hasTouch` option of the browser context be set to true.

-        In the case of multiple pages in a single browser, each page can have its own viewport size. However,

+        **Details**
+
+        This method checks or unchecks an element by performing the following steps:
+        1. Ensure that matched element is a checkbox or a radio input. If not, this method throws.
+        1. If the element already has the right checked state, this method returns immediately.
+        1. Wait for [actionability](https://playwright.dev/python/docs/actionability) checks on the matched element, unless `force` option is set. If
+           the element is detached during the checks, the whole action is retried.
+        1. Scroll the element into view if needed.
+        1. Use `page.mouse` to click in the center of the element.
+        1. Ensure that the element is now checked or unchecked. If not, this method throws.
 
-        `page.setViewportSize` will resize the page. A lot of websites don't expect phones to change size, so you should set the
-        viewport size before navigating to the page.
+        When all steps combined have not finished during the specified `timeout`, this method throws a `TimeoutError`.
+        Passing zero timeout disables this.

-        1. Find an element match matching `selector`. If there is none, wait until a matching element is attached to the DOM.
-        1. Wait for [actionability](./actionability.md) checks on the matched element, unless `force` option is set. If the
-           element is detached during the checks, the whole action is retried.
-        1. Scroll the element into view if needed.
-        1. Use `page.mouse` to click in the center of the element, or the specified `position`.
-        1. Wait for initiated navigations to either succeed or fail, unless `noWaitAfter` option is set.
+        Parameters
+        ----------
+        url : str
+            Target URL.
+        params : Union[Dict[str, Union[bool, float, str]], str, None]
+            Query parameters to be sent with the URL.
+        headers : Union[Dict[str, str], None]
+            Allows to set HTTP headers. These headers will apply to the fetched request as well as any redirects initiated by
+            it.
+        data : Union[Any, bytes, str, None]
+            Allows to set post data of the request. If the data parameter is an object, it will be serialized to json string
+            and `content-type` header will be set to `application/json` if not explicitly set. Otherwise the `content-type`
+            header will be set to `application/octet-stream` if not explicitly set.
+        form : Union[Dict[str, Union[bool, float, str]], None]
+            Provides an object that will be serialized as html form using `application/x-www-form-urlencoded` encoding and sent
+            as this request body. If this parameter is specified `content-type` header will be set to
+            `application/x-www-form-urlencoded` unless explicitly provided.
+        multipart : Union[Dict[str, Union[bool, bytes, float, str, {name: str, mimeType: str, buffer: bytes}]], None]
+            Provides an object that will be serialized as html form using `multipart/form-data` encoding and sent as this
+            request body. If this parameter is specified `content-type` header will be set to `multipart/form-data` unless
+            explicitly provided. File values can be passed as file-like object containing file name, mime-type and its content.
+        timeout : Union[float, None]
+            Request timeout in milliseconds. Defaults to `30000` (30 seconds). Pass `0` to disable timeout.
+        fail_on_status_code : Union[bool, None]
+            Whether to throw on response codes other than 2xx and 3xx. By default response object is returned for all status
+            codes.
+        ignore_https_errors : Union[bool, None]
+            Whether to ignore HTTPS errors when sending network requests. Defaults to `false`.
+        max_redirects : Union[int, None]
+            Maximum number of request redirects that will be followed automatically. An error will be thrown if the number is
+            exceeded. Defaults to `20`. Pass `0` to not follow redirects.
+        max_retries : Union[int, None]
+            Maximum number of times network errors should be retried. Currently only `ECONNRESET` error is retried. Does not
+            retry based on HTTP response codes. An error will be thrown if the limit is exceeded. Defaults to `0` - no retries.
 
-        When all steps combined have not finished during the specified `timeout`, this method rejects with a `TimeoutError`.
-        Passing zero timeout disables this.

         Parameters
         ----------
-        selector : str
-            A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See
-            [working with selectors](./selectors.md#working-with-selectors) for more details.
-        modifiers : Union[List[Union["Alt", "Control", "Meta", "Shift"]], NoneType]
-            Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores current
-            modifiers back. If not specified, currently pressed modifiers are used.
-        position : Union[typing.Tuple[float, float], NoneType]
-            A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of the
-            element.
-        delay : Union[float, NoneType]
-            Time to wait between `mousedown` and `mouseup` in milliseconds. Defaults to 0.
-        button : Union["left", "middle", "right", NoneType]
-            Defaults to `left`.
-        click_count : Union[int, NoneType]
-            defaults to 1. See [UIEvent.detail].
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds, defaults to 30 seconds, pass `0` to disable timeout. The default value can be changed by
-            using the `browser_context.set_default_timeout()` or `page.set_default_timeout()` methods.
-        force : Union[bool, NoneType]
-            Whether to bypass the [actionability](./actionability.md) checks. Defaults to `false`.
-        no_wait_after : Union[bool, NoneType]
-            Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can
-            opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as navigating to
-            inaccessible pages. Defaults to `false`.

+
+        Sends HTTP(S) [POST](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST) request and returns its
+        response. The method will populate request cookies from the context and update context cookies from the response.
+        The method will automatically follow redirects.
+
+        **Usage**
+
+        JSON objects can be passed directly to the request:
+
+        To send form data to the server use `form` option. Its value will be encoded into the request body with
+        `application/x-www-form-urlencoded` encoding (see below how to use `multipart/form-data` form encoding to send
+        files):
+
+        ```python
+        formData = {
+            \"title\": \"Book Title\",
+            \"body\": \"John Doe\",
+        }
+        api_request_context.post(\"https://example.com/api/findBook\", form=formData)
+        ```
 
-        This method taps an element matching `selector` by performing the following steps:
-        1. Find an element match matching `selector`. If there is none, wait until a matching element is attached to the DOM.
-        1. Wait for [actionability](./actionability.md) checks on the matched element, unless `force` option is set. If the
-           element is detached during the checks, the whole action is retried.
-        1. Scroll the element into view if needed.
-        1. Use `page.touchscreen` to tap the center of the element, or the specified `position`.
-        1. Wait for initiated navigations to either succeed or fail, unless `noWaitAfter` option is set.
+        The common way to send file(s) in the body of a request is to upload them as form fields with `multipart/form-data`
+        encoding. Use `FormData` to construct request body and pass it to the request as `multipart` parameter:
+
+        ```python
+        api_request_context.post(
+          \"https://example.com/api/uploadScript'\",
+          multipart={
+            \"fileField\": {
+              \"name\": \"f.js\",
+              \"mimeType\": \"text/javascript\",
+              \"buffer\": b\"console.log(2022);\",
+            },
+          })
+        ```
 
-        When all steps combined have not finished during the specified `timeout`, this method rejects with a `TimeoutError`.
-        Passing zero timeout disables this.

+        base_url : Union[str, None]
+            Methods like `a_pi_request_context.get()` take the base URL into consideration by using the

+            Examples:
+            - baseURL: `http://localhost:3000` and sending request to `/bar.html` results in `http://localhost:3000/bar.html`
+            - baseURL: `http://localhost:3000/foo/` and sending request to `./bar.html` results in
+              `http://localhost:3000/foo/bar.html`
+            - baseURL: `http://localhost:3000/foo` (without trailing slash) and navigating to `./bar.html` results in
+              `http://localhost:3000/bar.html`
+        extra_http_headers : Union[Dict[str, str], None]
+            An object containing additional HTTP headers to be sent with every request. Defaults to none.
+        http_credentials : Union[{username: str, password: str, origin: Union[str, None], send: Union["always", "unauthorized", None]}, None]
+            Credentials for [HTTP authentication](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication). If no
+            origin is specified, the username and password are sent to any servers upon unauthorized responses.
+        ignore_https_errors : Union[bool, None]
+            Whether to ignore HTTPS errors when sending network requests. Defaults to `false`.
+        proxy : Union[{server: str, bypass: Union[str, None], username: Union[str, None], password: Union[str, None]}, None]
+            Network proxy settings.
+        user_agent : Union[str, None]
+            Specific user agent to use in this context.
+        timeout : Union[float, None]
+            Maximum time in milliseconds to wait for the response. Defaults to `30000` (30 seconds). Pass `0` to disable
+            timeout.
+        storage_state : Union[pathlib.Path, str, {cookies: Sequence[{name: str, value: str, domain: str, path: str, expires: float, httpOnly: bool, secure: bool, sameSite: Union["Lax", "None", "Strict"]}], origins: Sequence[{origin: str, localStorage: Sequence[{name: str, value: str}]}]}, None]

+            TLS Client Authentication allows the server to request a client certificate and verify it.
+
+            **Details**
+
+            An array of client certificates to be used. Each certificate object must have either both `certPath` and `keyPath`,
+            a single `pfxPath`, or their corresponding direct value equivalents (`cert` and `key`, or `pfx`). Optionally,
+            `passphrase` property should be provided if the certificate is encrypted. The `origin` property should be provided
+            with an exact match to the request origin that the certificate is valid for.
+
+            **NOTE** When using WebKit on macOS, accessing `localhost` will not pick up client certificates. You can make it
+            work by replacing `localhost` with `local.playwright`.
+
+        fail_on_status_code : Union[bool, None]
+            Whether to throw on response codes other than 2xx and 3xx. By default response object is returned for all status
+            codes.
+        max_redirects : Union[int, None]
+            Maximum number of request redirects that will be followed automatically. An error will be thrown if the number is
+            exceeded. Defaults to `20`. Pass `0` to not follow redirects. This can be overwritten for each request
+            individually.

-        This method hovers over an element matching `selector` by performing the following steps:

-        1. Wait for [actionability](./actionability.md) checks on the matched element, unless `force` option is set. If the
-           element is detached during the checks, the whole action is retried.
-        1. Scroll the element into view if needed.
-        1. Use `page.mouse` to hover over the center of the element, or the specified `position`.
-        1. Wait for initiated navigations to either succeed or fail, unless `noWaitAfter` option is set.
+        Ensures the page is navigated to the given URL.

-        Returns the PDF buffer.
+        Ensures the `Locator` points to an element with given CSS classes. All classes from the asserted value, separated
+        by spaces, must be present in the
+        [Element.classList](https://developer.mozilla.org/en-US/docs/Web/API/Element/classList) in any order.
 
-        > **NOTE** Generating a pdf is currently only supported in Chromium headless.
+        **Usage**
 
-        `page.pdf()` generates a pdf of the page with `print` css media. To generate a pdf with `screen` media, call
-        `page.emulate_media()` before calling `page.pdf()`:
+        ```html
+        <div class='middle selected row' id='component'></div>
+        ```
 
-        > **NOTE** By default, `page.pdf()` generates a pdf with modified colors for printing. Use the
-        [`-webkit-print-color-adjust`](https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-print-color-adjust) property to
-        force rendering of exact colors.
+        ```py
+        from playwright.sync_api import expect
 
-        The `width`, `height`, and `margin` options accept values labeled with units. Unlabeled values are treated as pixels.
+        locator = page.locator(\"#component\")
+        expect(locator).to_contain_class(\"middle selected row\")
+        expect(locator).to_contain_class(\"selected\")
+        expect(locator).to_contain_class(\"row middle\")
+        ```
 
-        A few examples:
-        - `page.pdf({width: 100})` - prints with width set to 100 pixels
-        - `page.pdf({width: '100px'})` - prints with width set to 100 pixels
-        - `page.pdf({width: '10cm'})` - prints with width set to 10 centimeters.
+        When an array is passed, the method asserts that the list of elements located matches the corresponding list of
+        expected class lists. Each element's class attribute is matched against the corresponding class in the array:
 
-        All possible units are:
-        - `px` - pixel
-        - `in` - inch
-        - `cm` - centimeter
-        - `mm` - millimeter
+        ```html
+        <div class='list'>
+          <div class='component inactive'></div>
+          <div class='component active'></div>
+          <div class='component inactive'></div>
+        </div>
+        ```
 
-        The `format` options are:
-        - `Letter`: 8.5in x 11in
-        - `Legal`: 8.5in x 14in
-        - `Tabloid`: 11in x 17in
-        - `Ledger`: 17in x 11in
-        - `A0`: 33.1in x 46.8in
-        - `A1`: 23.4in x 33.1in
-        - `A2`: 16.54in x 23.4in
-        - `A3`: 11.7in x 16.54in
-        - `A4`: 8.27in x 11.7in
-        - `A5`: 5.83in x 8.27in

-        height : Union[float, str, NoneType]
-            Paper height, accepts values labeled with units.
-        prefer_css_page_size : Union[bool, NoneType]
-            Give any CSS `@page` size declared in the page priority over what is declared in `width` and `height` or `format`
-            options. Defaults to `false`, which will scale the content to fit the paper size.
-        margin : Union[{top: Union[float, str, NoneType], right: Union[float, str, NoneType], bottom: Union[float, str, NoneType], left: Union[float, str, NoneType]}, NoneType]
-            Paper margins, defaults to none.
-        path : Union[pathlib.Path, str, NoneType]
-            The file path to save the PDF to. If `path` is a relative path, then it is resolved relative to the current working
-            directory. If no path is provided, the PDF won't be saved to the disk.

         Parameters
         ----------
-        executable_path : Union[pathlib.Path, str, NoneType]
-            Path to a browser executable to run instead of the bundled one. If `executablePath` is a relative path, then it is
-            resolved relative to the current working directory. Note that Playwright only works with the bundled Chromium, Firefox
-            or WebKit, use at your own risk.
-        args : Union[List[str], NoneType]
-            Additional arguments to pass to the browser instance. The list of Chromium flags can be found
-            [here](http://peter.sh/experiments/chromium-command-line-switches/).
-        ignore_default_args : Union[List[str], bool, NoneType]
-            If `true`, Playwright does not pass its own configurations args and only uses the ones from `args`. If an array is
-            given, then filters out the given default arguments. Dangerous option; use with care. Defaults to `false`.
-        handle_sigint : Union[bool, NoneType]
-            Close the browser process on Ctrl-C. Defaults to `true`.
-        handle_sigterm : Union[bool, NoneType]
-            Close the browser process on SIGTERM. Defaults to `true`.
-        handle_sighup : Union[bool, NoneType]
-            Close the browser process on SIGHUP. Defaults to `true`.
-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds to wait for the browser instance to start. Defaults to `30000` (30 seconds). Pass `0` to
-            disable timeout.
-        env : Union[Dict[str, Union[bool, float, str]], NoneType]
-            Specify environment variables that will be visible to the browser. Defaults to `process.env`.
-        headless : Union[bool, NoneType]
-            Whether to run browser in headless mode. More details for
-            [Chromium](https://developers.google.com/web/updates/2017/04/headless-chrome) and
-            [Firefox](https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Headless_mode). Defaults to `true` unless the
-            `devtools` option is `true`.
-        devtools : Union[bool, NoneType]
-            **Chromium-only** Whether to auto-open a Developer Tools panel for each tab. If this option is `true`, the `headless`
-            option will be set `false`.
-        proxy : Union[{server: str, bypass: Union[str, NoneType], username: Union[str, NoneType], password: Union[str, NoneType]}, NoneType]
-            Network proxy settings.
-        downloads_path : Union[pathlib.Path, str, NoneType]
-            If specified, accepted downloads are downloaded into this directory. Otherwise, temporary directory is created and is
-            deleted when browser is closed.
-        slow_mo : Union[float, NoneType]
-            Slows down Playwright operations by the specified amount of milliseconds. Useful so that you can see what is going on.
-        chromium_sandbox : Union[bool, NoneType]
-            Enable Chromium sandboxing. Defaults to `false`.
-        firefox_user_prefs : Union[Dict[str, Union[bool, float, str]], NoneType]
-            Firefox user preferences. Learn more about the Firefox user preferences at
-            [`about:config`](https://support.mozilla.org/en-US/kb/about-config-editor-firefox).
+        error_message : Union[Pattern[str], str]

+        The opposite of `locator_assertions.to_have_role()`.
 
         Parameters
         ----------
-        user_data_dir : Union[pathlib.Path, str]
-            Path to a User Data Directory, which stores browser session data like cookies and local storage. More details for

-        executable_path : Union[pathlib.Path, str, NoneType]
-            Path to a browser executable to run instead of the bundled one. If `executablePath` is a relative path, then it is
-            resolved relative to the current working directory. **BEWARE**: Playwright is only guaranteed to work with the bundled
-            Chromium, Firefox or WebKit, use at your own risk.
-        args : Union[List[str], NoneType]
-            Additional arguments to pass to the browser instance. The list of Chromium flags can be found

-        timeout : Union[float, NoneType]
-            Maximum time in milliseconds to wait for the browser instance to start. Defaults to `30000` (30 seconds). Pass `0` to
-            disable timeout.
-        env : Union[Dict[str, Union[bool, float, str]], NoneType]
-            Specify environment variables that will be visible to the browser. Defaults to `process.env`.
-        headless : Union[bool, NoneType]
-            Whether to run browser in headless mode. More details for
-            [Chromium](https://developers.google.com/web/updates/2017/04/headless-chrome) and
-            [Firefox](https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Headless_mode). Defaults to `true` unless the
-            `devtools` option is `true`.
-        devtools : Union[bool, NoneType]

-        downloads_path : Union[pathlib.Path, str, NoneType]
-            If specified, accepted downloads are downloaded into this directory. Otherwise, temporary directory is created and is
-            deleted when browser is closed.
-        slow_mo : Union[float, NoneType]
-            Slows down Playwright operations by the specified amount of milliseconds. Useful so that you can see what is going on.
-            Defaults to 0.
-        viewport : Union["0", typing.Tuple[int, int], NoneType]
-            Sets a consistent viewport for each page. Defaults to an 1280x720 viewport. `null` disables the default viewport.
