Phase 4: Component Tests - React Components & UI

**Part of:** #170
**Depends on:** #171, #172

## 📋 Phase 4: Component Tests (Medium Priority)

### Scope
This phase focuses on testing React components and user interface validation.

### 5. **React Components** (`src/components/islands/`)
**Why important**: User interface validation, but lower priority due to complexity.

#### Core Interactive Components
- [ ] `search.jsx` - Search functionality
- [ ] `word-editor.jsx` - Word editing interface
- [ ] `profile.jsx` - User profile display
- [ ] `recent-searches.jsx` - Search history

#### Test Focus
- [ ] Component rendering
- [ ] User interactions
- [ ] State management
- [ ] Error boundaries
- [ ] Accessibility testing
- [ ] Responsive design validation

## 🎯 Success Criteria
- 60%+ coverage for React components
- All user interactions tested
- Accessibility standards met
- Error boundaries properly tested
- State management validated

## 📅 Timeline
**Week 4** of testing implementation (Part 1)

## 🛠️ Setup Required
- Set up React Testing Library
- Configure component testing environment
- Create component test fixtures
- Set up accessibility testing tools

Start by reviewing the components in src/components/islands/: search.jsx, word-editor.jsx, profile.jsx, and recent-searches.jsx. Set up React Testing Library, the component testing environment, fixtures, and accessibility tooling described in the issue. Done means the components have rendering, interaction, state, error-boundary, accessibility, and responsive tests, with at least 60% coverage.
