Web Testing Skill

Comprehensive web testing: unit, integration, E2E, load, security, visual regression, accessibility.

Quick Start

npx vitest run                    # Unit tests
npx playwright test               # E2E tests
npx playwright test --ui          # E2E with UI
k6 run load-test.js               # Load tests
npx @axe-core/cli https://example.com  # Accessibility
npx lighthouse https://example.com     # Performance

  --output markdown

Parses Playwright/Vitest/JUnit results into unified summary.

CI/CD Integration

jobs:
  test:
    steps:
      - run: npm run test:unit      # Gate 1: Fast fail
      - run: npm run test:e2e       # Gate 2: After unit pass
      - run: npm run test:a11y      # Accessibility
      - run: npx lhci autorun       # Performance
