Learn how to run your Python automation testing scripts on the LambdaTest platform

Prerequisites

Before you can start performing Python automation testing with Selenium, you would need to:

Install the latest Python build from the official website. We recommend using the latest version.
Make sure pip is installed in your system. You can install pip from here.
Download the latest Selenium Client and its WebDriver bindings from the official website. Latest versions of Selenium Client and WebDriver are ideal for running your automation script on LambdaTest Selenium cloud grid.

Installing Selenium Dependencies And Tutorial Repo

Step 1: Clone the LambdaTest’s python-selenium-sample repository and navigate to the code directory as shown below:

git clone -b Python-AutoHealing-Demo https://github.com/LambdaTest/python-selenium-sample.git
cd Python-AutoHealing-Demo

Step 2: Download the driver from the link, or you can use pip to install it.

pip install -r requirements.txt
export PYTHONWARNINGS="ignore:Unverified HTTPS request"   //Disable ssl warning

Setting Up Your Authentication

Make sure you have your LambdaTest credentials with you to run test automation scripts. You can get these credentials from the LambdaTest Automation Dashboard or by your LambdaTest Profile.

Step 2: Set LambdaTest Username and Access Key in environment variables.

For Linux/macOS:

export LT_USERNAME="YOUR_USERNAME" 
export LT_ACCESS_KEY="YOUR ACCESS KEY"

For Windows:

set LT_USERNAME="YOUR_USERNAME" 
set LT_ACCESS_KEY="YOUR ACCESS KEY"

Run Your First Test

Test Scenario: This test automates the process of searching for a book titled "Python Programming" in the Books category on Amazon.in using the LambdaTest platform.

📋 Test Steps

The script initializes a remote WebDriver session on LambdaTest with the desired capabilities (Windows 10, Chrome browser).
The Amazon.in website is loaded.
The script updates the ID attributes of the search submit button and search textbox.
The search category dropdown is clicked to reveal the list of categories.
The 'Books' category is selected from the dropdown.
The term "Python Programming" is entered into the search textbox.
The search button is clicked to initiate the search.

With AutoHeal Enable, the test scenario passed even after updating the ID attribute of submit button.

Configuration Of Your Test Capabilities

Step 4: In the python script, you need to update your test capabilities. In this code, we are passing browser, browser version, and operating system information, along with LambdaTest Selenium grid capabilities via capabilities object.

The capabilities object in the above code are defined as:

 # Desired capabilities for the test
        desired_caps = {
            'LT:Options': {
                "build": "Auto Heal Demo",
                "name": "Auto Heal Enabled",
                "platformName": "Windows 10",
                "autoHeal": 'true',
            },
            "browserName": "Chrome",
            "browserVersion": "latest",
        }
}

You can generate capabilities for your test requirements with the help of our inbuilt Desired Capability Generator.

Executing The Test

Execution Steps:

Install the required libraries:
```
pip install -r requirements.txt
```

Run the test:

python autoHealingEnableDemo.py && python autoHealingDisableDemo.py

Your test results would be displayed on the test console (or command-line interface if you are using terminal/cmd) and on LambdaTest automation dashboard.

Testing Locally Hosted Or Privately Hosted Projects

You can test your locally hosted or privately hosted projects with LambdaTest Selenium grid using LambdaTest Tunnel. All you would have to do is set up an SSH tunnel using tunnel and pass toggle tunnel = True via desired capabilities. LambdaTest Tunnel establishes a secure SSH protocol based tunnel that allows you in testing your locally hosted or privately hosted pages, even before they are live.

Refer our LambdaTest Tunnel documentation for more information.

Here’s how you can establish LambdaTest Tunnel.

Download the binary file of:

LambdaTest Tunnel for Windows
LambdaTest Tunnel for macOS
LambdaTest Tunnel for Linux

Open command prompt and navigate to the binary folder.

Run the following command:

LT -user {user’s login email} -key {user’s access key}

So if your user name is lambdatest@example.com and key is 123456, the command would be:

LT -user lambdatest@example.com -key 123456

Once you are able to connect LambdaTest Tunnel successfully, you would just have to pass on tunnel capabilities in the code shown below :

Tunnel Capability

"tunnel" : true
