6.6Key Takeaways
- Browser contexts provide lightweight, isolated sessions — no state leaks between tests
- Auto-waiting checks actionability (visible, stable, enabled) before every interaction
- Web-first assertions retry until the condition is met, eliminating race conditions
- Use
waitFor()andwaitForResponse()only when you need to wait for async operations beyond simple interactions - Never use instant assertions on dynamic content — always use
expect()from@playwright/test
