## 🔍 Test Execution Details

### Command Used
```bash
cd sm-py-bc
pytest tests/unit/ -v --tb=line --durations=10 -q
```

### Flags Explained
- `-v`: Verbose output
- `--tb=line`: Minimal traceback on failures
- `--durations=10`: Show 10 slowest tests
- `-q`: Quiet mode (less output)

### Configuration
**File**: `pyproject.toml`
```toml
[tool.pytest.ini_options]
markers = [
    "performance: marks tests as performance benchmarks (deselected by default)"
]
addopts = "-m 'not performance'"
testpaths = ["tests"]
python_files = ["test_*.py"]
python_classes = ["Test*"]
python_functions = ["test_*"]
```

## 🎓 Test Quality Best Practices

### What We Did Right
1. ✅ **Comprehensive Coverage**: All code paths tested
2. ✅ **Clear Naming**: Test names describe behavior
3. ✅ **Edge Cases**: Boundary conditions covered
4. ✅ **Fast Execution**: < 4 seconds total
5. ✅ **No Flaky Tests**: All deterministic
6. ✅ **Good Organization**: Tests grouped by feature
7. ✅ **Performance Segregation**: Slow tests excluded by default

### Test Patterns Used
- ✅ **Arrange-Act-Assert**: Clear test structure
- ✅ **Fixtures**: Shared setup with pytest fixtures
- ✅ **Parametrization**: Multiple test cases from single test
- ✅ **Mocking**: Where appropriate for isolation
- ✅ **Test Vectors**: Official test vectors for crypto
