  - Original behavior preservation
  - Empty environment variable handling

- **Direct URL Parsing Method Tests (9 tests)**
  - Complete URL parsing
  - Minimal URL parsing
  - Default vhost parsing

  - Malformed URL error handling

## Key Test Features

### ✅ **Comprehensive Property Testing**
- Valid input handling
- Invalid input rejection with appropriate errors
- Type conversion testing
- Default value behavior
- URL cache invalidation

### ✅ **Robust Error Testing**
- Custom exception handling
- Error message validation
- Type safety enforcement
- Recovery from error states

### ✅ **Integration Testing**
- Component interaction validation
- End-to-end workflow testing
- Logger integration across components
- Package-level import testing

### ✅ **Edge Case Coverage**
- Invalid type handling via `setattr()` for type safety
- String-to-integer conversion edge cases
- URL caching and invalidation scenarios
- Multiple configuration change scenarios

### ✅ **Mocking & Isolation**
- Logger functionality mocked for unit testing
- Property access via `getattr()` to avoid private member access
- Mock verification for debug logging calls

## Test Infrastructure

### **Configuration**
- `conftest.py`: Test fixtures and logging configuration
- Automated logging disabling during tests
- Warren instance fixtures for common test scenarios

### **Type Safety**
- Uses `setattr()` and `# type: ignore` for testing invalid types
- Avoids direct private member access in tests
- Uses `getattr()` for checking internal state

### **Continuous Integration Ready**
- All tests designed to run in CI environments
- No external dependencies beyond pytest and mock
- Deterministic test execution

## Missing Coverage Areas (10%)
The remaining 10% of uncovered code consists of:
- Some error handling branches in Warren class property getters
- Specific edge cases in type validation
- Fallback error paths in property setters

These areas represent defensive programming code paths that are difficult to trigger in normal operation but provide robustness.

## Test Execution
```bash
# Run all tests
pytest tests/ -v

# Run with coverage
pytest tests/ --cov=bunnystream --cov-report=term-missing

# Run specific test module  
pytest tests/test_warren.py -v
```

## Quality Metrics
- **76 tests** covering all major functionality
- **90% code coverage** across the package
- **Zero test failures** 
- **Comprehensive error scenario testing**
- **Integration and unit test mix**
- **Type-safe testing approaches**
