## 🎯 Usage

### Quick Start
```bash
# Run all infrastructure tests
make test

# Run WASM browser tests
make test-wasm

# Run E2E tests
make test-e2e-enhanced

# Run performance benchmarks
make benchmark

# Run accessibility audit
make accessibility-audit
```

### Advanced Usage
```bash
# Run tests on specific browsers
make test-wasm-browsers BROWSERS=chromium,firefox

# Run with specific WCAG level
make accessibility-audit-wcag LEVEL=AAA

# Run performance regression tests
make regression-test

# Start automated monitoring
make performance-monitor
```

## 📊 Performance Metrics

- **WASM Initialization**: <5s (Chrome) to <10s (Mobile Safari)
- **First Paint**: <3s (Chrome) to <5s (Mobile Safari)
- **Interaction Latency**: <100ms average
- **Memory Usage**: <50% increase during operations
- **WCAG Compliance**: AA level with AAA support

## 🎉 Impact

This infrastructure provides:
- **Reliable Component Development**: Comprehensive testing and validation
- **Performance Excellence**: Automated performance monitoring and optimization
- **Accessibility Compliance**: WCAG compliance validation and reporting
- **Production Deployment**: CI/CD integration with automated testing

## 🚀 Next Steps

Ready for Phase 3: Component Completion
- Complete remaining 41 components using established patterns
- Leverage infrastructure for comprehensive testing
- Ensure production-ready quality across all components

**Status**: ✅ PHASE 2 COMPLETE - READY FOR PRODUCTION

+
+## Test Categories
+
+### WCAG $WCAG_LEVEL Compliance
+- Testing against Web Content Accessibility Guidelines
+- ARIA compliance validation
+- Semantic HTML structure verification
+
+### Keyboard Navigation
+- Full keyboard accessibility testing
+- Logical focus order validation
+- Tab navigation support
+
+### Screen Reader Support
+- Proper landmark structure
+- Live regions for dynamic content
+- Skip links for navigation
+
+### Color and Contrast
+- Sufficient color contrast ratios
+- Color-only information detection
+
+### Focus Management
+- Proper focus handling in modals
+- Focus restoration after interactions
+
+## Key Recommendations
+
+1. **Ensure all interactive elements have accessible names**
+   - Use aria-label, aria-labelledby, or visible text content
+   - Provide meaningful descriptions for screen readers
+
+2. **Provide proper form labels and associations**
+   - Use for/id attributes to associate labels with inputs
+   - Include instructions and error messages
+
+3. **Use semantic HTML elements and ARIA landmarks**
+   - Implement proper heading structure
+   - Add navigation landmarks
+
+4. **Implement proper focus management for modals**
+   - Trap focus within modal dialogs
+   - Restore focus after modal close
+
+5. **Maintain sufficient color contrast ratios**
+   - Meet WCAG AA standards (4.5:1 for normal text)
+   - Test with color contrast analyzers
+
+6. **Test with actual screen readers and keyboard navigation**
+   - Use real assistive technologies
+   - Validate with actual users
+
+## Running Accessibility Tests
+
+To run accessibility tests manually:
+
+\`\`\`bash
+# Run all accessibility tests
+make test-e2e-accessibility
+
+# Run specific accessibility test file
+pnpm playwright test tests/e2e/accessibility-enhanced.spec.ts
+
+# Run with verbose output
+pnpm playwright test tests/e2e/accessibility-enhanced.spec.ts --reporter=list
+\`\`\`
