What are some tips for debugging Playwright tests?

Here are some tips for debugging Playwright tests:

1. Use the --debug flag to run tests in debug mode.
2. Utilize the page.pause() method to pause execution and inspect the page.
3. Take advantage of the Playwright Inspector for step-by-step debugging.
4. Check the console logs for any errors or warnings.
5. Use trace to record and analyze test runs.

How do I use the Playwright Inspector?

To use the Playwright Inspector, run your tests with the DEBUG=pw:api environment variable set. This will open the Inspector when a test is executed, allowing you to step through the code, inspect elements, and see the state of the page.

Can I debug tests in headless mode?

Yes, you can debug tests in headless mode by using the headless: false option in your browser launch configuration. This will allow you to see the browser actions while still running the tests.

What should I do if my tests are flaky?

If your tests are flaky, consider the following:

1. Ensure that your tests are not dependent on external factors like network speed.
2. Use waitFor methods to handle asynchronous operations properly.
3. Isolate tests to avoid shared state issues.
4. Review your test data and environment setup.
