Diagnose and fix a Playwright test that fails or passes intermittently using a systematic taxonomy.
$ARGUMENTS contains:
e2e/login.spec.ts"the checkout test fails in CI but passes locally"Run the test to capture the error:
npx playwright test <file> --reporter=list
If the test passes, it's likely flaky. Run burn-in:
npx playwright test <file> --repeat-each=10 --reporter=list
If it still passes, try with parallel workers:
npx playwright test --fully-parallel --workers=4 --repeat-each=5
Run with full tracing:
npx playwright test <file> --trace=on --retries=0
Read the trace output. Use /debug to analyze trace files if available.

Every failing test falls into one of four categories:
| Category | Symptom | Diagnosis |
|---|---|---|
| Timing/Async | Fails intermittently everywhere | --repeat-each=20 reproduces locally |
| Test Isolation | Fails in suite, passes alone | --workers=1 --grep "test name" passes |
| Environment | Fails in CI, passes locally | Compare CI vs local screenshots/traces |
| Infrastructure | Random, no pattern | Error references browser internals |

retries: 2)Run the test 10 times to confirm stability:
npx playwright test <file> --repeat-each=10 --reporter=list
All 10 must pass. If any fail, go back to step 3.
