Run on CI

Run Playwright tests on every push or PR via your CI provider.

GitHub Actions

Use the official Playwright action for setup.

- uses: actions/checkout@v4
- uses: actions/setup-node@v4
- run: npm ci
- run: npx playwright install --with-deps
- run: npm run test:e2e

Caching

Cache ~/.cache/ms-playwright to skip downloading browsers each run.

Parallelism

Playwright parallelizes within a job; you can also shard tests across multiple jobs.

Artifacts

Upload traces, screenshots, and reports on failure for easy debugging.

- uses: actions/upload-artifact@v4
  if: always()
  with: { name: playwright-report, path: playwright-report/ }

Containers

The official Playwright Docker image has all browsers pre-installed.

Headless Only on CI

CI almost always runs headless. Locally use headed for debugging.

Retries

Configure retries for known flaky network-dependent tests.

retries: process.env.CI ? 2 : 0

Slow Tests

Mark slow tests with annotations so CI can prioritize.

Reporters

Use HTML, JSON, or JUnit reporters depending on your CI dashboard preferences.

Self-Hosted Runners

For Mac/iOS testing, use self-hosted runners with Safari support.

Quick Check
