## Testing Best Practices

1. **Isolation**: Each test is independent and doesn't affect others
2. **Clarity**: Test names clearly describe what is being tested
3. **Coverage**: Both success and failure paths are tested
4. **Edge Cases**: Null, empty, and boundary conditions are covered
5. **Resources**: Test resources are properly managed and cleaned up
