Test Validation Loop
After writing or modifying tests:
- Run tests:
npx playwright test --reporter=list - If tests fail:
- Review error output and trace (
npx playwright show-trace) - Fix locators, waits, or assertions
- Re-run tests
- Review error output and trace (
- Only proceed when all tests pass
- Run multiple times for critical tests:
npx playwright test --repeat-each=5
