Comprehensive Error Handling - Exception testing for all custom exception classes - Edge case validation (empty inputs, invalid formats) - Network failure simulation - Database error scenarios - Rate limiting and timeout handling ### 2. Async/Await Pattern Testing - Proper async context management - Concurrent operation testing - Lock and synchronization validation - Background task lifecycle management - Async exception handling ### 3. Mock-Based Isolation - Database operations fully mocked - External API calls mocked with realistic responses - Time-based operations using controlled mocks - Random number generation for predictable testing - File system operations mocked where appropriate ### 4. Security Testing - Timing attack prevention validation - Cryptographic operation testing - Token security and validation - Rate limiting enforcement - Audit trail verification ### 5. Integration Scenarios - Complete workflow testing (end-to-end processes) - Component interaction validation - Error propagation testing - Failover and recovery scenarios - Load balancing and routing validation ## Running the Tests ### Quick Test Run ```bash # From shared package root python -m pytest tests/ -v ``` ### Coverage Report ```bash # Generate HTML coverage report python -m pytest tests/ --cov=src/shared --cov-report=html # View coverage report open htmlcov/index.html ``` ### Run Specific Test Categories ```bash # Run only encryption tests python -m pytest tests/test_encryption.py -v # Run security-related tests python -m pytest -m security -v # Run integration tests python -m pytest -m integration -v ``` ### Using the Test Runner ```bash # Comprehensive test run with coverage validation python run_tests.py ``` ## Test Quality Metrics ### Coverage Requirements - **Minimum Coverage: 90%** for all modules - **Target Coverage: 95%** for core security and encryption modules - **Branch Coverage: 85%** minimum for complex conditional logic - **Function Coverage: 98%** for all public APIs ### Test Quality Standards - **Assertion Quality**: Specific, meaningful assertions with clear failure messages - **Test Isolation**: No shared state between tests, proper setup/teardown - **Mocking Strategy**: Comprehensive mocking to isolate units under test - **Error Testing**: Every error condition has corresponding test cases - **Documentation**: Clear test names and docstrings explaining test purpose ### Performance Standards - **Unit Tests**: < 100ms per test method - **Integration Tests**: < 1s per test method - **Total Suite**: < 30s for complete test run - **Memory Usage**: < 200MB peak during test execution ## Continuous Integration ### Pre-commit Hooks - Automatic test execution on code changes - Coverage validation before commits - Code quality checks (linting, type checking) - Security vulnerability scanning ### CI/CD Pipeline Integration - Automated test execution on pull requests - Coverage reporting to code review tools - Test failure notifications - Performance regression detection ## Maintenance and Updates ### Test Maintenance Schedule - **Weekly**: Review and update any flaky or outdated tests - **Monthly**: Analyze coverage reports and add tests for uncovered edge cases - **Quarterly**: Review test performance and optimize slow tests - **Release Cycle**: Comprehensive test review and validation ### Adding New Tests 1. Follow existing test structure and naming conventions 2. Use appropriate fixtures from `conftest.py` 3. Add relevant markers for test categorization 4. Ensure 90%+ coverage for new functionality 5. Include both positive and negative test cases 6. Document complex test scenarios in docstrings This comprehensive test suite ensures robust, reliable, and maintainable code with excellent coverage and quality validation.
