feat: Add comprehensive Vue component testing infrastructure

- Add Vitest configuration with JSDOM environment for Vue component testing - Create RegistrationNotice component mock with full TypeScript support - Implement comprehensive test suite for RegistrationNotice component (18 tests) - Add test setup with global mocks for ResizeObserver, IntersectionObserver, etc. - Update package.json with testing dependencies (@vue/test-utils, jsdom, vitest) - Add test scripts: test, test:unit, test:unit:watch, test:unit:coverage - Exclude Playwright tests from Vitest to prevent framework conflicts - Add comprehensive documentation with usage examples and best practices - All tests passing (20/20) with proper Vue-facing-decorator support

+# TimeSafari Testing Documentation
+
+## Overview
+
+This directory contains comprehensive testing infrastructure for the TimeSafari application, including mocks, test utilities, and examples for Vue components using vue-facing-decorator.
+
+## Testing Setup
+
+### Dependencies
+
+The testing setup uses:
+
+- **Vitest**: Fast unit testing framework
+- **JSDOM**: DOM environment for browser-like testing
+- **@vue/test-utils**: Vue component testing utilities
+- **vue-facing-decorator**: TypeScript decorators for Vue components
+
+### Configuration Files
+
+- `vitest.config.ts`: Main Vitest configuration
+- `src/test/setup.ts`: Test environment setup and global mocks
+
+## RegistrationNotice Component Mock
+
+### Overview
+
+The `RegistrationNotice` component is the simplest component in the codebase (34 lines) and serves as an excellent example for testing Vue components with vue-facing-decorator.
+
+### Mock Implementation
+
+**File**: `src/test/__mocks__/RegistrationNotice.mock.ts`
+
+The mock provides:
+- Same interface as the original component
+- Simplified behavior for testing
+- Additional helper methods for test scenarios
+- Full TypeScript support
+
+### Key Features
+
+```typescript
+// Basic usage
+const mockComponent = new RegistrationNoticeMock()
+mockComponent.isRegistered = false
+mockComponent.show = true
+
+// Test helper methods
+expect(mockComponent.shouldShow).toBe(true)
+expect(mockComponent.buttonText).toBe('Share Your Info')
+expect(mockComponent.noticeText).toContain('Before you can publicly announce')
+
+// Event emission
+mockComponent.shareInfo() // Emits 'share-info' event
+```
+
+### Testing Patterns
+
+#### 1. Direct Mock Usage
+```typescript
+it('should create mock component with correct props', () => {
+  const mockComponent = new RegistrationNoticeMock()
+  mockComponent.isRegistered = false
+  mockComponent.show = true
+  
+  expect(mockComponent.shouldShow).toBe(true)
+})
+```
+
+#### 2. Vue Test Utils Integration
+```typescript
+it('should mount mock component with props', () => {
+  const wrapper = mount(RegistrationNoticeMock, {
+    props: {
+      isRegistered: false,
+      show: true
+    }
+  })
+  
+  expect(wrapper.vm.shouldShow).toBe(true)
+})
+```
+
+#### 3. Event Testing
+```typescript
+it('should emit share-info event', async () => {
+  const wrapper = mount(RegistrationNoticeMock, {
+    props: { isRegistered: false, show: true }
+  })
+  
+  await wrapper.vm.shareInfo()
+  
+  expect(wrapper.emitted('share-info')).toBeTruthy()
+})
+```
+
+#### 4. Custom Mock Behavior
+```typescript
+class CustomRegistrationNoticeMock extends RegistrationNoticeMock {
+  override get buttonText(): string {
+    return 'Custom Button Text'
+  }
+}
+```
+
+#### 5. Advanced Testing Patterns
+
+```typescript
+// Spy methods for testing
+const mockComponent = new RegistrationNoticeMock()
+const shareInfoSpy = vi.spyOn(mockComponent, 'shareInfo')
+const mockClickSpy = vi.spyOn(mockComponent, 'mockShareInfoClick')
+
+mockComponent.mockShareInfoClick()
+expect(mockClickSpy).toHaveBeenCalledTimes(1)
+expect(shareInfoSpy).toHaveBeenCalledTimes(1)
+```
+
+#### 6. Integration Testing
+```typescript
+// Simulate parent component context
+const parentData = {
+  isUserRegistered: false,
+  shouldShowNotice: true
+}
+
+const mockComponent = new RegistrationNoticeMock()
+mockComponent.isRegistered = parentData.isUserRegistered
+mockComponent.show = parentData.shouldShowNotice
+
+expect(mockComponent.shouldShow).toBe(true)
+```
+
+#### 7. State Change Testing
+```typescript
+const mockComponent = new RegistrationNoticeMock()
+
+// Initial state
+mockComponent.isRegistered = false
+mockComponent.show = true
+expect(mockComponent.shouldShow).toBe(true)
+
+// State change
+mockComponent.isRegistered = true
+expect(mockComponent.shouldShow).toBe(false)
+```
+
+#### 8. Performance Testing
+```typescript
+const mockComponent = new RegistrationNoticeMock()
+const startTime = performance.now()
+
+// Call methods rapidly
+for (let i = 0; i < 1000; i++) {
+  mockComponent.shareInfo()
+  mockComponent.shouldShow
+  mockComponent.buttonText
+}
+
+const duration = performance.now() - startTime
+expect(duration).toBeLessThan(100) // Should complete quickly
+```
+
+## Running Tests
+
+### Available Scripts
+
+```bash
+# Run all tests
+npm run test
+
+# Run unit tests once
+npm run test:unit
+
+# Run unit tests in watch mode
+npm run test:unit:watch
+
+# Run tests with coverage
+npm run test:unit:coverage
+```
+
+### Test File Structure
+
+```
+src/test/
+├── __mocks__/
+│   └── RegistrationNotice.mock.ts    # Component mock
+├── setup.ts                          # Test environment setup
+├── RegistrationNotice.test.ts         # Component tests
+└── README.md                         # This documentation
+```
+
+## Testing Best Practices
+
+### 1. Component Testing
+- Test component rendering with different prop combinations
+- Verify event emissions
+- Check accessibility attributes
+- Test user interactions
+
+### 2. Mock Usage
+- Use mocks for isolated unit testing
+- Test component interfaces, not implementation details
+- Create custom mocks for specific test scenarios
+- Verify mock behavior matches real component
+
+### 3. Error Handling
+- Test edge cases and error conditions
+- Verify graceful degradation
+- Test invalid prop combinations
+
+### 4. Performance Testing
+- Test rapid method calls
+- Verify efficient execution
+- Monitor memory usage in long-running tests
+
+## Security Audit Checklist
+
+When creating mocks and tests, ensure:
+
+- [ ] No sensitive data in test files
+- [ ] Proper input validation testing
+- [ ] Event emission security
+- [ ] No hardcoded credentials
+- [ ] Proper error handling
+- [ ] Access control verification
+- [ ] Data sanitization testing
+
+## Examples
+
+See `src/test/RegistrationNotice.mock.example.ts` for comprehensive examples covering:
+- Direct mock usage
+- Vue Test Utils integration
+- Event testing
+- Custom mock behavior
+- Integration testing
+- Error handling
+- Performance testing
+
+## Troubleshooting
+
+### Common Issues
+
+1. **JSDOM Environment Issues**
+   - Ensure `vitest.config.ts` has `environment: 'jsdom'`
+   - Check `src/test/setup.ts` for proper global mocks
+
+2. **Vue-facing-decorator Issues**
+   - Ensure TypeScript configuration supports decorators
+   - Verify import paths are correct
+
+3. **Test Utils Issues**
+   - Check component mounting syntax
+   - Verify prop passing
+   - Ensure proper async/await usage
+
+### Debug Tips
+
+```bash
+# Run tests with verbose output
+npm run test:unit -- --reporter=verbose
+
+# Run specific test file
+npm run test:unit src/test/RegistrationNotice.test.ts
+
+# Debug with console output
+npm run test:unit -- --reporter=verbose --no-coverage
+```
+
+## Contributing
+
+When adding new mocks or tests:
+
+1. Follow the existing patterns in `RegistrationNotice.mock.ts`
+2. Add comprehensive documentation
+3. Include usage examples
+4. Update this README with new information
+5. Add security audit checklist items
