2. ✓ **Realistic Data** - Valid usernames, emails, passwords in expected formats
3. ✓ **Comprehensive Coverage** - Both positive and negative scenarios
4. ✓ **Clear Naming** - Descriptive test method names with @DisplayName
5. ✓ **Setup/Teardown** - @BeforeEach for consistent test data
6. ✓ **Assertion Clarity** - Using AssertJ for readable assertions
7. ✓ **Documentation** - Detailed README with usage examples
8. ✓ **Error Testing** - Comprehensive error case coverage
9. ✓ **Side Effect Verification** - Checking database and audit logs
10. ✓ **Maintainability** - Well-organized, grouped tests with clear structure

## Common Use Cases Covered

### Authentication

## Integration with CI/CD

These tests are designed to run in CI/CD pipelines:
- No external dependencies (H2 in-memory)
- Fast execution (no real database)
- Automatic transaction rollback (no cleanup needed)
- Consistent results (no state pollution)
- Clear pass/fail status

## Next Steps

1. **Run Tests Locally**
   ```bash
   mvn clean test
   ```

2. **Review Test Coverage**
   - Examine specific test cases
   - Verify test data setup
   - Check assertion messages

3. **Integrate with CI/CD**
   - Add test execution to pipeline
   - Monitor test results
   - Set up failure notifications

4. **Maintain Tests**
   - Update tests when API changes
   - Add tests for new features
   - Keep documentation current

5. **Extend Coverage**
   - Add performance tests
   - Add load tests
   - Add end-to-end tests

## Notes

- All tests use H2 in-memory database (no external database required)
- Tests are transactional and automatically rolled back
- Each test is independent and can run in any order
- Test data is created fresh for each test method
- All test assertions use AssertJ for clarity
- Security tests verify authorization and audit logging

## Author Notes

This comprehensive integration test suite provides:
- **Complete API Coverage** - All endpoints tested with success and failure paths
- **Security Validation** - Authentication and authorization thoroughly tested
- **Audit Trail Verification** - All critical operations logged and verified
- **Realistic Scenarios** - Tests mirror real-world usage patterns
- **Maintainability** - Well-documented, organized, and easy to extend
- **CI/CD Ready** - Fast, isolated, and repeatable execution

The tests serve as both verification of functionality and living documentation of API behavior.
