9. Testing & Validation

9.1 Animation Testing ⭐ RECOMMENDED NEXT TASK

Priority: Medium
Effort: Medium
Status: Partially Complete (Accessibility ✅, Performance Testing ⏳)

Rationale: After implementing numerous animations (list entries, modals, level indicators, tag/filter badges), it’s critical to ensure performance and accessibility compliance before production deployment.

Tasks:

Animation Performance
- Test animations on lower-end devices (Android 8+ with 2GB RAM)
- Profile animation performance using React Native Performance Monitor
- Ensure 60fps performance during all animations
- Test with 100+ products in list
- Measure scroll performance with FlatList optimizations
- Identify and optimize any heavy animations
Animation Accessibility ✅ COMPLETE (2026-01-07)
- ✅ Created useReducedMotion hook to detect motion preferences
- ✅ Respect prefers-reduced-motion system setting (iOS, Android, Web)
- ✅ Disable or scale down animations when reduced motion is enabled
- ⏳ Test with screen readers (VoiceOver, TalkBack) - PENDING
- ⏳ Ensure animations don’t interfere with accessibility announcements - PENDING
Animation Edge Cases
- Test rapid state changes (multiple rapid taps)
- Test animations during scroll/interaction
- Verify animations complete properly on component unmount
- Test with slow/interrupted user interactions

Files Created:

✅ shaker/utils/useReducedMotion.ts - Hook to detect motion preferences (supports iOS, Android, Web)

Files Modified:

✅ shaker/components/ProductLevelIndicator.tsx - Respects reduced motion for fill transitions and pulse
✅ shaker/app/(tabs)/inventory/products/index.tsx - List entry animations and tag badges respect reduced motion
✅ shaker/components/products/ProductFilters.tsx - Filter badges respect reduced motion
✅ shaker/components/Button.tsx - Press feedback respects reduced motion
✅ shaker/components/Modal.tsx - Slide up and backdrop animations respect reduced motion
✅ shaker/components/Toast.tsx - Slide in animations respect reduced motion

Implementation Details:

The useReducedMotion hook:

Uses AccessibilityInfo.isReduceMotionEnabled() for iOS/Android
Uses CSS media query (prefers-reduced-motion: reduce) for Web
Listens for system setting changes and updates reactively
Falls back to allowing motion if API fails (graceful degradation)

Components Updated:

ProductLevelIndicator: Fill transitions skip animation, pulse disabled when reduced motion is enabled
AnimatedTagBadge & AnimatedFilterBadge: Scale animations skip spring physics when reduced motion is enabled
ProductCard: List entry animations (FadeInDown/FadeOutUp) disabled when reduced motion is enabled
Button: Press scale animation disabled when reduced motion is enabled
Modal: Slide up and scale animations disabled, instant show/hide when reduced motion is enabled
Toast: Slide in animation disabled, instant show/hide when reduced motion is enabled

All components maintain their final visual state (no animation) when reduced motion is preferred, ensuring full functionality while respecting user preferences.
