+# GARM Webapp Unit Tests
+
+This directory contains unit tests for the GARM webapp, focusing on testing individual components and utility functions.
+
+## Test Structure
+
+### Setup Files
+- `setup.ts` - Global test setup and mocks for SvelteKit modules
+- `mocks.ts` - Mock factories for API clients, stores, and external dependencies
+- `factories.ts` - Factory functions for creating test data objects
+
+### Test Files
+- `src/routes/repositories/page.test.ts` - Comprehensive tests for the repositories list page
+
+## Running Tests
+
+```bash
+# Run all tests once
+npm run test:run
+
+# Run tests in watch mode
+npm run test
+
+# Run tests with UI (if vitest UI is installed)
+npm run test:ui
+```
+
+## Test Coverage
+
+The repositories page tests cover:
+
+### Page Loading
+- ✅ Page title rendering
+- ✅ Loading state management
+- ✅ Error handling during data fetching
+- ✅ Cache manager integration
+
+### Repository List Rendering
+- ✅ Repository data display
+- ✅ GitHub forge icon rendering
+- ✅ Gitea forge icon rendering
+- ✅ Status badge generation
+- ✅ Column configuration
+- ✅ Mobile card configuration
+
+### Search and Filtering
+- ✅ Repository filtering by name
+- ✅ Repository filtering by owner
+- ✅ Search term handling
+- ✅ Empty search results
+
+### Pagination
+- ✅ Page navigation
+- ✅ Items per page changes
+- ✅ Total pages calculation
+- ✅ Pagination controls
+
+### Action Buttons and Modals
+- ✅ Edit repository action
+- ✅ Delete repository action
+- ✅ Create repository modal
+- ✅ Modal state management
+
+### Repository Operations
+- ✅ Repository creation
+- ✅ Repository creation with webhook installation
+- ✅ Repository updates
+- ✅ Repository deletion
+- ✅ Webhook installation
+
+### Error Handling
+- ✅ API error handling
+- ✅ Creation error handling
+- ✅ Webhook installation error handling
+- ✅ Cache error handling
+
+### Toast Notifications
+- ✅ Success notifications
+- ✅ Error notifications
+- ✅ Operation feedback
+
+### Cache Management
+- ✅ Cache retry functionality
+- ✅ Cache state management
+
+## Testing Strategy
+
+The tests follow these principles:
+
+1. **Unit Testing Focus**: Tests focus on isolated functionality rather than full component integration
+2. **Mock External Dependencies**: All API calls, stores, and external utilities are mocked
+3. **Test Behavior, Not Implementation**: Tests verify expected behavior and user interactions
+4. **Comprehensive Coverage**: Tests cover happy paths, error scenarios, and edge cases
+5. **Readable Test Names**: Test descriptions clearly explain what functionality is being tested
+
+## Mock Strategy
+
+- **API Client**: Mocked to simulate successful and failed operations
+- **Stores**: Mocked to provide predictable state management
+- **Utilities**: Mocked to test business logic independently
+- **Components**: Heavy components are mocked to focus on page logic
+
+This approach ensures fast, reliable tests that validate the repositories page functionality without depending on external services or complex component rendering.
