Compatibility Testing
<default_to_action> When validating cross-browser/platform compatibility:
- DEFINE browser matrix (cover 95%+ of users)
- TEST responsive breakpoints (mobile, tablet, desktop)
- RUN in parallel across browsers/devices
- USE cloud services for device coverage (BrowserStack, Sauce Labs)
- COMPARE visual screenshots across platforms
Quick Compatibility Checklist:
- Chrome, Firefox, Safari, Edge (latest + N-1)
- Mobile Safari (iOS), Mobile Chrome (Android)
- Screen sizes: 320px, 768px, 1920px
- Test on actual target devices for critical flows
Critical Success Factors:
- Users access from 100+ browser/device combinations
- Test where users are, not where you develop
