Testing / Playwright Interview questions

How can you integrate Playwright tests into a CI/CD pipeline?

The scaffolded project already includes a working GitHub Actions workflow, which is a reasonable template for most CI providers:

# .github/workflows/playwright.yml
- uses: actions/setup-node@v4
- run: npm ci
- run: npx playwright install --with-deps
- run: npx playwright test
- uses: actions/upload-artifact@v4
  if: always()
  with:
    name: playwright-report
    path: playwright-report/

The --with-deps flag matters on Linux CI runners specifically, since it installs the OS-level libraries the browsers need beyond just the browser binaries themselves. Enabling trace: 'on-first-retry' in config and uploading the report and trace as build artifacts (with if: always(), so it runs even on failure) means a failing CI run leaves behind exactly the diagnostic evidence needed to debug it, instead of just a red X with no further detail.

For larger suites, adding a shard matrix (--shard=${{ matrix.shard }}/4 across a 4-job matrix) parallelizes the whole run across CI machines rather than one job working through everything sequentially.

The --with-deps flag on npx playwright install is important because it:
Using if: always() when uploading the report artifact ensures:
