- Debug Playwright E2E tests
SKILL.md
Goal
- Reproduce, debug, and fix Playwright E2E failures with minimal flakiness.
Inputs (ask only if missing)
- Which spec to focus on (file name / test title / failing step).
- Target build (Chrome/Firefox) if relevant.
Steps
- Ensure build artifact exists (E2E前提)
yarn build
- Run E2E
yarn e2e
- If tests depend on a live stream URL
- Prefer search results (e.g.
https://www.youtube.com/results?search_query=vtuber&sp=EgJAAQ%253D%253D) - Pick a result with a "Live" badge; if it fails to open, fall back to the next one
- Avoid hardcoding a single live URL (streams end and cause flaky tests)
- Prefer search results (e.g.
- If you need to focus on a single test/spec
- Try passing Playwright args through yarn:
yarn e2e -- <args>(例:yarn e2e -- e2e/foo.spec.ts)
- If pass-through is not supported, run Playwright directly (repoの慣習に合わせる)
- Try passing Playwright args through yarn:
- Gather debugging artifacts (when failing)
- Prefer Playwright trace/screenshots/video if enabled in config
- Re-run once to confirm determinism (no infinite retries)
- Fix strategy (flakinessを増やさない)
- Avoid sleep/timeouts; wait on explicit UI/state:
await expect(locator).toBeVisible()await expect(locator).toHaveText(...)
- Use stable selectors (role/text/testid など、プロジェクトの既存パターンに合わせる)
- Network依存はfixturesで置き換える(可能なら)
- Avoid sleep/timeouts; wait on explicit UI/state:
- Validate
yarn e2eが連続で通ることを確認(最低2回が理想)
Notes
e2e/fixtures.tsの拡張test/expectを使う前提。- 非決定的挙動を増やす修正(ランダム待ち/過剰リトライ)は避ける。
- ネイティブチャットの表示/操作可否は「拡張ON/OFFの前後」で必ず確認する。
Output format
- Repro steps(実行したコマンド)
- Live URL used(該当時)
- Root cause(推定でなく根拠ベース)
- Fix summary(どこをどう変えたか)
- Verification(通ったコマンド)
