UI Mode turns failures into time-travel debugging

Playwright's new UI Mode brings a watch mode together with the trace viewer to create a time-travel debugging experience.  Edit your tests in watch mode and upon saving your file the tests are rerun with a new trace of the tests. Walk through each action of your test and visually see what happened before and after each step of the test. Inspect the DOM snapshot, see network requests, the console and the log of your test.
