Although Playwright is the web testing tool you use for frontend testing, sometimes your tests need to interact with some APIs, for example, to get test data from the server.... To achieve reliable visual testing, it’s crucial to prevent unreliable tests by effectively hiding dynamic parts of your application.

The test function is invoked with two parameters: a descriptive string that names the test case, “get started link”, and an asynchronous callback function that contains the logic for executing the test. Inside of the callback function we inject a ‘page’. This one is of the most important elements of the Playwright.
