Web accessibility ensures applications work for users with disabilities. Screen readers, keyboard navigation, and color contrast affect usability. Testing identifies and prevents accessibility barriers.
Testing Methods
Automated tools catch common issues quickly. Manual testing verifies screen reader experience. Keyboard testing ensures navigation without mouse. User testing with people with disabilities provides real feedback.
- Run automated tools like axe-core in CI pipelines
- Test keyboard navigation through entire flows
- Verify screen reader experience with NVDA or VoiceOver
- Check color contrast ratios meet WCAG standards
- Include people with disabilities in user testing
Common Issues
Missing alt text prevents image understanding. Poor color contrast reduces readability. Missing form labels confuse screen readers. Focus management breaks keyboard navigation.
