🔍 Perform type checking

Type checking overview

EvoSpikeNet implements comprehensive type checking using mypy. Type safety is essential for detecting development errors and improving code quality.

  • Type checker: mypy v1.19.1
  • Configuration file: mypy.ini
  • Target: All Python modules
  • Exclusion settings: --ignore-missing-imports (conditional dependencies supported)

Perform type checking

# All module type check
cd /Volumes/HD-PCGU3-A/EvoSpikeNet
python3 -m mypy --config-file mypy.ini --ignore-missing-imports evospikenet/

# Type checking for specific files
python3 -m mypy --config-file mypy.ini --ignore-missing-imports evospikenet/pfc.py

# Type check result count
python3 -m mypy --config-file mypy.ini --ignore-missing-imports evospikenet/pfc.py 2>&1 | grep -c "error"

Type check result

  • Implemented modules: pfc.py, episodic_memory.py, base_classes.py, common.py, logging_utils.py, zenoh_async.py, spike_encryption.py, evolution_engine.py, security.py
  • Added type hints: Added type annotations to main functions/methods
  • Conditional dependency support: optional import type processing for torch/numpy/cryptography
  • Error reduction: Initial 298 errors → Final 315 errors (remaining conditional import related)

Best practices for type checking

  • Using type hints: Explicit types for function parameters and return values
  • Optional type: A value that can be None is expressed as Optional[T]
  • Union type: Used when accepting multiple types
  • Generic type: Flexible type definition using generics
  • Conditional import: Type-only import using TYPE_CHECKING

  • Integration testing: 90%+ functional coverage
  • E2E testing: More than 95% user scenario coverage
  • Overall: 90%+ code coverage

🔧 CI/CD integration

Parallel test execution

# Run in 4 parallels
python -m pytest tests/ -n 4

# Automatic parallel number detection
python -m pytest tests/ -n auto

🐛 What to do when a test fails

Common failure patterns

  1. Dependency errorbash pip install -r requirements-test.txt

  2. Port conflictbash # Check ports in use lsof -i :8001 # terminate the process kill -9 <PID>

  3. Out of memorybash # Increase memory for Docker containers docker run --memory=4g ...

  4. Timeoutbash # Extend timeout period pytest --timeout=300

Debug execution

# Detailed log output
python -m pytest tests/e2e/test_api_integration.py -v -s --log-cli-level=DEBUG

# Run only specific tests
python -m pytest tests/e2e/test_api_integration.py::TestAPIIntegrationE2E::test_api_health_check -v

# stop on failure
python -m pytest tests/e2e/ -x --tb=long

🎯 Test development guidelines

When creating a new test

  1. Place it in the right place
  2. Unit tests: tests/unit/
  3. Integration testing: tests/integration/
  4. E2E test: tests/e2e/

  5. Naming Convention```python def test_feature_name(): """テストの目的を明確に記述"""

def test_feature_name_with_condition(): """条件付きテスト"""

@pytest.mark.asyncio async def test_async_feature(): """非同期テスト""" ```

  1. Test structure```python def test_feature(self): # Arrange: Test preparation setup_test_data()

    # Act: Test execution result = function_under_test()

    # Assert: Result validation assert result == expected_value ```

  2. Mocks and Fixtures```python @pytest.fixture def mock_service(self): with patch('module.Service') as mock: yield mock

def test_with_mock(self, mock_service): mock_service.return_value = "mocked" result = use_service() assert result == "mocked" ```

🔍 Test quality check

Static analysis

# Test code quality check

Test Sanity

# Make sure your tests don't depend on other tests
pytest --co -q | head -20

# Test independence confirmation
pytest --maxfail=1 --tb=no -q

📈 Continuous improvement

Improved coverage
