Excited about the new selector syntax for querying open shadow roots in Puppeteer: It is also possible to add your own extensions and use them in selectors. 🎉 It makes e2e testing apps with web components so much easier.

Any other actions can now be edited without stopping the recording. For example, you can change the type field to "waitForExpression" and specify a JavaScript expression to wait for instead of waiting for elements. Updating selectors for any action is possible as well

Did you know that DevTools Recorder supports extensions? You can also build your own and use the recorded information to generate test cases for your project/test runner/code style.

Recorder lets you configure recorded selectors. ARIA/Text selectors aren't always computable, so include a backup type. For test attributes like data-test-id, Recorder detects them and uses these IDs for CSS/XPath selectors automatically. If you can customize selector attr too.
