You can run a single test, a set of tests or all tests. Tests can be run on different browsers. By default tests are run in a headless manner meaning no browser window will be opened while running the tests and results will be seen in the terminal. If you prefer you can run your tests in headed mode by using the
headless test run parameter.
Running all tests
Running a single test file
dotnet test --filter "MyClassName"
Run a set of test files
dotnet test --filter "MyClassName1|MyClassName2"
Run the test with the title
dotnet test --filter "Name~TestMethod1"
Running Tests on specific browsers
dotnet test -- Playwright.BrowserName=webkit
Running Tests on multiple browsers
To run your test on multiple browsers or configurations you need to invoke the
dotnet testcommand multiple times. There you can then either specify the
BROWSERenvironment variable or set the
Playwright.BrowserNamevia the runsettings file:
dotnet test --settings:chromium.runsettings
dotnet test --settings:firefox.runsettings
dotnet test --settings:webkit.runsettings
<?xml version="1.0" encoding="utf-8"?>
For more information see selective unit tests in the Microsoft docs.
Since Playwright runs in .NET, you can debug it with your debugger of choice in e.g. Visual Studio Code or Visual Studio. Playwright comes with the Playwright Inspector which allows you to step through Playwright API calls, see their debug logs and explore selectors.
