Accessibility Testing
Testing that software is usable by people with disabilities, following WCAG guidelines.
Full definition
Accessibility testing verifies that software can be used by people with disabilities — visual, auditory, motor, and cognitive. It ensures compliance with standards like WCAG (Web Content Accessibility Guidelines) and legal requirements like the ADA.
Key accessibility testing areas:
- Screen reader compatibility: Can blind users navigate with NVDA/VoiceOver?
- Keyboard navigation: Can all functionality be accessed without a mouse?
- Color contrast: Is text readable for color-blind users?
- Focus management: Is the focus indicator visible and logical?
- Alt text: Do images have meaningful descriptions?
- Form labels: Are form fields properly labeled for assistive technology?
WCAG conformance levels:
- Level A: Minimum accessibility (must meet)
- Level AA: Standard level (most legal requirements target this)
- Level AAA: Enhanced accessibility (aspirational)
Tools: axe DevTools, Lighthouse, WAVE, Pa11y, screen readers (NVDA, VoiceOver)
Accessibility isn't just about compliance — accessible software is better software for everyone.
