## Uncovered Controllers

The following controllers have **0% coverage**:
- `admin.controller.js` - 0 tests
- `home.controller.js` - 0 tests
- `operational.controller.js` - 0 tests
- `user.address.controller.js` - 0 tests
- `user.payment.controller.js` - 0 tests
- `user.wishlist.controller.js` - 0 tests

## Test Improvements Made

### Fixed Issues
1. ✅ **ESM Compatibility:** Fixed `jest.mock` not defined errors by importing jest from `@jest/globals`
2. ✅ **MongoDB ObjectIds:** Updated tests to use valid ObjectId format (24-character hex strings)
3. ✅ **Event Publisher Tests:** Fixed integration tests by mocking `@dapr/dapr` and enabling DAPR_ENABLED
4. ✅ **Import Paths:** Fixed relative import paths in integration and e2e tests
5. ✅ **Dynamic DAPR Check:** Refactored publisher to check DAPR_ENABLED dynamically instead of at module load

### Tests Added
1. ✅ **Auth Middleware Tests:** 11 tests covering requireAuth and optionalAuth
2. ✅ **CorrelationId Middleware Tests:** 8 tests covering all scenarios
3. ✅ **Model Tests:** 12 placeholder tests for user model structure
4. ✅ **E2E Documentation:** Comprehensive setup guide for e2e tests

## Recommendations for Further Improvement

### Priority 1: Critical Coverage Gaps
1. **Add controller tests** for:
- `admin.controller.js` (0% coverage)
- `user.address.controller.js` (0% coverage)
- `user.payment.controller.js` (0% coverage)
- `user.wishlist.controller.js` (0% coverage)
- `operational.controller.js` (0% coverage)
- `home.controller.js` (0% coverage)

2. **Add infrastructure tests** for:
- `database/db.js` (connection, error handling)
- `config.js` (configuration validation)
- `dapr.js` (service invocation, state management)

### Priority 2: Improve Existing Coverage
1. **User Controller:** Increase from 57.73% to >80%
- Add tests for error paths
- Add tests for edge cases
- Add tests for missing required fields

2. **Event Publisher:** Increase from 71.15% to >85%
- Add tests for error handling
- Add tests for Dapr connection failures
- Add tests for event formatting edge cases

3. **Logger:** Increase from 65% to >80%
- Add tests for different log levels
- Add tests for metadata sanitization
- Add tests for error scenarios

### Priority 3: Integration Testing
1. **Add database integration tests:**
- Test actual MongoDB operations
- Test schema validations
- Test indexes and constraints

2. **Add API integration tests:**
- Test request/response flows
- Test middleware chains
- Test error handling

### Priority 4: E2E Testing
1. **Automate E2E test setup:**
- Create Docker Compose for test environment
- Add scripts to wait for services
- Add cleanup scripts

2. **Expand E2E test coverage:**
- Add tests for address management
- Add tests for payment methods
- Add tests for wishlist operations

## Running Tests

### All Tests (Excluding E2E)
```bash
npm test
```

### Unit Tests Only
```bash
npm run test:unit
```

### Integration Tests Only
```bash
npm run test:integration
```

### E2E Tests (Requires Running Service)
```bash
npm run test:e2e
```

### Coverage Report
```bash
npm run test:coverage
```

## Files Changed

### Test Files Added
- `tests/unit/middlewares/auth.middleware.test.js` (8,064 bytes, 11 tests)
- `tests/unit/middlewares/correlationId.middleware.test.js` (4,090 bytes, 8 tests)
- `tests/unit/models/user.model.test.js` (2,534 bytes, 12 tests)
- `tests/e2e/README.md` (2,094 bytes, documentation)

### Source Files Modified
- `src/events/publisher.js` - Refactored isDaprEnabled() to check dynamically
- `src/events/index.js` - Fixed duplicate content syntax error
- `tests/unit/services/user.service.test.js` - Fixed ESM imports and ObjectIds
- `tests/integration/user-event-publisher.integration.test.js` - Fixed mocking
- `tests/integration/user.controller.test.js` - Fixed import paths
- `tests/e2e/user-api.e2e.test.js` - Fixed import path

## Conclusion

The test suite has been significantly improved with:
- **296 passing tests** (97% success rate)
- **35.91% overall coverage** (increased from ~30%)
- **All unit and integration tests passing**
- **Comprehensive documentation for E2E tests**

The main areas requiring attention are:
1. Controller tests (currently 13% coverage)
2. Infrastructure tests (database, config, dapr - 0% coverage)
3. E2E test automation

With these improvements, the codebase has a solid foundation for continuous testing and quality assurance.
