Once your API is up and running, it’s crucial to write tests to ensure it is bug-free and to prevent future regressions. A good practice is to follow a Test-Driven Development (TDD) approach, where tests are written before the production code.

API Platform provides a set of helpful testing utilities to write unit tests, functional tests, and to create test fixtures.

• If you are using API Platform with Symfony, refer to the Testing the API with Symfony documentation.
• If you are using API Platform with Laravel, refer to the Testing the API with Laravel documentation.
