Accessibility Testing Automation Pipeline for CI/CD Integration

Design an automated accessibility testing pipeline for [PRODUCT NAME] built with [FRAMEWORK] and deployed via [CI/CD PLATFORM].\\\\\\\\n\\\\\\\\n**Automated Testing Layers:**\\\\\\\\n\\\\\\\\nLayer 1 — Linting (on every save):\\\\\\\\n- ESLint plugin: eslint-plugin-jsx-a11y\\\\\\\\n- Stylelint for CSS accessibility (focus styles, contrast)\\\\\\\\n- Template linting for HTML semantics\\\\\\\\n- Blocking: prevent commit if critical violations found\\\\\\\\n\\\\\\\\nLayer 2 — Unit Testing (on every commit):\\\\\\\\n- Jest + jest-axe for component-level accessibility\\\\\\\\n- Test each component's ARIA attributes\\\\\\\\n- Test keyboard navigation\\\\\\\\n- Test screen reader announcements\\\\\\\\n\\\\\\\\nLayer 3 — Integration Testing (on every PR):\\\\\\\\n- Playwright/Cypress with axe-core\\\\\\\\n- Test critical user flows:\\\\\\\\n  1. Login/authentication\\\\\\\\n  2. [FLOW 2]\\\\\\\\n  3. [FLOW 3]\\\\\\\\n- Generate HTML report with violations\\\\\\\\n- PR comment with summary\\\\\\\\n\\\\\\\\nLayer 4 — Full Page Audit (on every deploy to staging):\\\\\\\\n- Lighthouse CI: accessibility score threshold (minimum 90)\\\\\\\\n- pa11y CI: WCAG 2.2 AA compliance check\\\\\\\\n- Screenshot comparison for visual regressions\\\\\\\\n- Report posted to Slack/Teams\\\\\\\\n\\\\\\\\n**Manual Testing Checkpoints:**\\\\\\\\n- Before major release: keyboard-only navigation test\\\\\\\\n- Monthly: screen reader testing (NVDA + VoiceOver)\\\\\\\\n- Quarterly: full WCAG 2.2 AA audit\\\\\\\\n- User testing with disabled participants (bi-annually)\\\\\\\\n\\\\\\\\n**Pipeline Configuration:**\\\\\\\\n\\\\\\\\\\\\\\\\\\\\\\\`\\\\\\\\\\\\\\\\\\\\\\\`\\\\\\\\\\\\\\\\\\\\\\\`yaml\\\\\\\\n# Example GitHub Actions workflow\\\\\\\\nname: Accessibility Tests\\\\\\\\non: [push, pull_request]\\\\\\\\njobs:\\\\\\\\n  a11y:\\\\\\\\n    runs-on: ubuntu-latest\\\\\\\\n    steps:\\\\\\\\n      - uses: actions/checkout@v4\\\\\\\\n      - run: npm ci\\\\\\\\n      - run: npm run lint:a11y\\\\\\\\n      - run: npm test -- --testPathPattern=a11y\\\\\\\\n      - run: npx playwright test a11y/\\\\\\\\n      - uses: actions/upload-artifact@v4\\\\\\\\n        with:\\\\\\\\n          name: a11y-report\\\\\\\\n          path: reports/a11y/\\\\\\\\n\\\\\\\\\\\\\\\\\\\\\\\`\\\\\\\\\\\\\\\\\\\\\\\`\\\\\\\\\\\\\\\\\\\\\\\`\\\\\\\\n\\\\\\\\n**Reporting and Tracking:**\\\\\\\\n- Dashboard: accessibility score trend over time\\\\\\\\n- Issue tracking: auto-create GitHub issues for violations\\\\\\\\n- Baseline: current violation count, target zero\\\\\\\\n- Team accountability: accessibility score per component\\\\\\\\n\\\\\\\\nInclude complete CI/CD configuration and test examples.
