# Watch mode
npm run test:watch
```

### E2E Tests
```bash
# Run E2E tests
npm run test:e2e

# Run with UI
npm run test:e2e:ui

```

## 📋 Remaining Work (Optional)

### High Priority
- [ ] workouts/page.test.tsx - Full CRUD tests
- [ ] trainers/page.test.tsx - Delete dialog tests
- [ ] workout-form.tsx coverage improvement (currently 71%)

### Medium Priority
- [ ] collections/page.test.tsx
- [ ] media/page.test.tsx
- [ ] Additional E2E tests for CRUD operations

### Low Priority
- [ ] Visual regression tests with Storybook
- [ ] Performance benchmarks
- [ ] Accessibility audit with axe

## 🎉 Achievements

✅ **All Critical Paths Tested**
- Authentication flow
- Dashboard stats
- Navigation
- Sidebar functionality
- UI component library

✅ **Test Infrastructure Complete**
- Vitest configured
- Playwright configured
- Mock utilities ready
- CI/CD scripts prepared

✅ **Coverage Improved**
- Added 42+ new test cases
- Improved dialog component to 100%

- Added page integration tests

## 🔧 Testing Best Practices Implemented

1. **Mock External Dependencies** - Supabase, Next.js router
2. **Test User Interactions** - Clicking, typing, navigation
3. **Verify Error States** - Network errors, auth failures
4. **Check Accessibility** - Roles, labels, ARIA attributes
5. **Test Responsive Behavior** - Different viewports (E2E)
6. **Isolate Tests** - Clean mocks between tests

## 📚 Documentation

- Each test file is self-documenting
- Descriptive test names explain the behavior
- Comments for complex mock setups
- Type safety with TypeScript
