## Running Tests

### Prerequisites

```bash
# Install main dependencies
pip install -r requirements.txt

# Install test dependencies
pip install -r requirements-test.txt
```

### Run All Tests

```bash
# Run all tests with coverage
pytest -v --cov=. --cov-report=term-missing

# Run all tests with HTML coverage report
pytest -v --cov=. --cov-report=html

# Run specific test file
pytest tests/test_genesis_boiler.py -v

# Run specific test class
pytest tests/test_genesis_boiler.py::TestGenesisBoilerInit -v

# Run specific test
pytest tests/test_genesis_boiler.py::TestGenesisBoilerInit::test_init_default_values -v
```

### Test Markers

Tests are marked with the following markers:

- `@pytest.mark.unit` - Unit tests
- `@pytest.mark.integration` - Integration tests
- `@pytest.mark.slow` - Slow-running tests
- `@pytest.mark.requires_network` - Tests requiring network access
- `@pytest.mark.requires_hf_token` - Tests requiring HuggingFace token

```bash
# Run only unit tests
pytest -v -m unit

# Run only integration tests
pytest -v -m integration

# Skip slow tests
pytest -v -m "not slow"

# Skip network-dependent tests
pytest -v -m "not requires_network"
```

### Coverage Reports

```bash
# Generate coverage report
coverage run -m pytest
coverage report

# Generate HTML coverage report
coverage html
# Open htmlcov/index.html in browser

# Generate XML coverage report (for CI/CD)
coverage xml
```

## Test Fixtures

### Common Fixtures (from conftest.py)

- `temp_dir` - Creates a temporary directory for testing
- `mock_env_vars` - Mocks environment variables
- `sample_python_file` - Creates a sample Python file
- `sample_directory_structure` - Creates a directory structure with files

### Usage Example

```python
def test_with_temp_dir(temp_dir):
    """Test using temp_dir fixture"""
    test_file = temp_dir / "test.txt"
    test_file.write_text("content")
    assert test_file.exists()

def test_with_mock_env(mock_env_vars):
    """Test using mocked environment variables"""
    assert os.getenv("HF_TOKEN") == "test_token_123"
```

## Writing New Tests

### Test Structure

```python
"""
Module docstring explaining what is being tested
"""
import pytest
from pathlib import Path
from unittest.mock import Mock, patch
import sys

# Add parent to path if needed
sys.path.insert(0, str(Path(__file__).parent.parent))

from module_to_test import ClassToTest


class TestClassName:
    """Test class with descriptive name"""

    def test_specific_functionality(self):
        """Test with clear description"""
        # Arrange
        obj = ClassToTest()

        # Act
        result = obj.method()

        # Assert
        assert result == expected_value
```

### Best Practices

1. **Descriptive Names**: Use clear, descriptive test names
2. **Arrange-Act-Assert**: Structure tests with clear sections
3. **One Assertion Per Test**: Focus each test on one behavior
4. **Use Fixtures**: Reuse common setup code via fixtures
5. **Mock External Dependencies**: Use mocks for external services
6. **Test Edge Cases**: Include error conditions and edge cases
7. **Document Tests**: Add docstrings explaining what is being tested

## Continuous Integration

Tests run automatically on:
- Push to `main`, `develop`, or `claude/*` branches
- Pull requests to `main`
- Manual workflow dispatch

### CI/CD Pipeline

1. **Test Job**: Runs tests on Python 3.10, 3.11, 3.12, 3.13
2. **Lint Job**: Runs ruff, black, isort
3. **Coverage Upload**: Uploads coverage to Codecov
4. **Artifacts**: Saves HTML coverage reports

## Areas for Future Improvement

### Missing Test Coverage

1. **Integration Tests**
   - End-to-end workflow tests
   - Multi-component integration tests
   - Real HuggingFace API tests (with token)

2. **Performance Tests**
   - Large file handling
   - Memory usage
   - Execution time benchmarks

3. **UI Tests**
   - Streamlit component testing
   - UI interaction tests
   - Visual regression tests

4. **Network Tests**
   - API endpoint tests
   - Model download tests (requires network)
   - GitHub API integration tests

### Recommendations

1. **Increase Coverage**
   - Add edge case tests
   - Test error recovery paths
   - Add boundary condition tests

2. **Add Integration Tests**
   - Test complete workflows
   - Test component interactions
   - Test with real data

3. **Performance Testing**
   - Add benchmarks for critical paths
   - Memory profiling
   - Load testing

4. **Documentation**
   - Add more test examples
   - Document testing patterns
   - Create testing guide

## Test Metrics

### Current Status (as of 2026-04-14)

- **Total Test Files**: 7
- **Total Test Cases**: 150+
- **Overall Coverage**: ~85%
- **Lines Covered**: ~1800+ lines
- **Branches Covered**: ~70%

### Coverage Goals

- **Target Coverage**: 90%
- **Minimum Coverage**: 80%
- **Critical Modules**: 95%+

## Troubleshooting

### Common Issues

1. **Import Errors**
   ```bash
   # Ensure all dependencies are installed
   pip install -r requirements.txt -r requirements-test.txt
   ```

2. **Path Issues**
   ```python
   # Use absolute paths in tests
   test_path = Path(__file__).parent.parent / "file.py"
   ```

3. **Fixture Not Found**
   ```python
   # Ensure conftest.py is in tests directory
   # Check fixture name matches
   ```

4. **Mock Not Working**
   ```python
   # Use correct patch target
   with patch('module.function') as mock_func:
       # Test code
   ```
