Creating Parameterized Tests with Playwright

With Playwright Test, you can easily create parameterized tests in JavaScript.

Test Level Parameterization

First, you can define an array of parameters and loop over them. Here's an example:

This will generate multiple tests, each with a different parameter value.

Project Level Parameterization

You can also define options for your tests using the extend function from Playwright Test.

In this example, the person option is defined with a default value of "John". You can override this value in the configuration file or when running the tests.

Using Fixtures with Options

You can use fixtures with options to further customize your tests. Fixtures let you set up reusable state or perform common actions before each test.

In this example, the page fixture is overridden to include the person parameter as a "name" for the chat room. Each test will receive a pre-configured page with the person's name already filled in.

By using Playwright Test's parameterization and fixture capabilities, you can create a template for similar tests in JavaScript that takes multiple parameters. This allows you to easily generate and customize tests based on different input values or configurations.
