# Accessibility Testing Skill

## Purpose
Systematically verify accessibility compliance through automated and manual testing.

## Testing Approach

### Automated Testing
1. Run axe-core or similar tools on each page
2. Integrate accessibility checks into CI/CD pipeline
3. Use Lighthouse for accessibility scoring
4. Check color contrast ratios programmatically

### Manual Testing
1. Navigate using keyboard only
2. Test with screen readers (NVDA, VoiceOver, JAWS)
3. Verify focus order is logical
4. Check that dynamic content updates are announced
5. Test at 200% zoom level

### Test Categories

- **Perceivable** - Content can be perceived by all users
