Running Tests

Using the Test Runner

# Run all unit tests
python tests/run_tests.py unit

# Run with verbose output and coverage
python tests/run_tests.py unit -v -c

# Run specific test file
python tests/run_tests.py unit -t test_advanced_file_manager.py

# Run all tests
python tests/run_tests.py all

# Run performance tests
python tests/run_tests.py performance

# Generate comprehensive report
python tests/run_tests.py report

Using Pytest Directly

# Run all unit tests
pytest tests/unit/

# Run with coverage
pytest tests/unit/ --cov=laxyfile --cov-report=html

# Run specific test
pytest tests/unit/test_advanced_file_manager.py

# Run with markers
pytest tests/ -m "unit"
pytest tests/ -m "performance"
pytest tests/ -m "slow"

Test Markers

Tests are organized with markers for selective execution:

@pytest.mark.unit: Unit tests
@pytest.mark.integration: Integration tests
@pytest.mark.e2e: End-to-end tests
@pytest.mark.performance: Performance tests
@pytest.mark.slow: Tests that take more than 1 second

Coverage Goals

The test suite aims for comprehensive coverage:

Line Coverage: >90% for all core components
Branch Coverage: >85% for critical paths
Function Coverage: 100% for public APIs
Integration Coverage: All component interactions

Performance Testing

Performance tests validate:

Response Times: Operations complete within acceptable timeframes
Memory Usage: Efficient memory management under load
Concurrency: Proper handling of concurrent operations
Scalability: Performance with large datasets

Continuous Integration

The test suite is designed for CI/CD integration:

Fast Execution: Unit tests complete quickly for rapid feedback
Parallel Execution: Tests can run in parallel for efficiency
Deterministic: Consistent results across different environments
Comprehensive Reporting: Detailed test results and coverage reports

Adding New Tests

When adding new functionality:

Create Unit Tests: Test individual components in isolation
Add Integration Tests: Test component interactions
Include Error Cases: Test failure scenarios and edge cases
Add Performance Tests: Validate performance requirements
Update Documentation: Document new test patterns and utilities

Test Naming Conventions

Test files: test_<component_name>.py
Test classes: Test<ComponentName>
Test methods: test_<functionality>_<scenario>
Fixtures: <component_name>_<type> (e.g., file_manager, mock_config)

Test Organization

Group related tests in classes
Use descriptive test names
Include docstrings for complex tests
Separate setup, execution, and assertion phases
Use fixtures for common test data

Dependencies

The test suite requires:

pytest: Core testing framework
pytest-asyncio: Async test support
pytest-cov: Coverage reporting
pytest-html: HTML test reports
pytest-benchmark: Performance testing
pytest-mock: Enhanced mocking capabilities

Install with:

pip install pytest pytest-asyncio pytest-cov pytest-html pytest-benchmark pytest-mock

Troubleshooting

Common Issues

Import Errors: Ensure LaxyFile is in Python path
Async Test Failures: Check pytest-asyncio configuration
Mock Issues: Verify mock object setup and patching
Performance Test Failures: Adjust timing thresholds for environment
Coverage Issues: Check file paths and exclusion patterns

Debug Mode

Run tests with debugging:

pytest tests/unit/ -v -s --tb=long --pdb

Test Isolation

Ensure tests are isolated:

Use temporary directories for file operations
Clean up resources in teardown
Avoid global state modifications
Use fresh mock objects for each test

Future Enhancements

Planned improvements:

Integration Tests: Component interaction testing
End-to-End Tests: Full workflow validation
Property-Based Testing: Hypothesis-based testing
Mutation Testing: Test quality validation
Visual Testing: UI component visual regression testing
