1. Auto-waiting is powerful - once you learn to combine it with waitForResponse() for API calls, tests become way more stable
2. Role-based locators are a game changer - getByRole and getByLabel make tests more readable and resilient than XPath ever was
3. The Playwright Inspector and codegen features speed up development massively - wish I’d used them from day one instead of writing everything manually
What’s your favorite Playwright feature?
