Test Organization

Test Markers

All tests are organized using pytest markers for easy filtering:

• @pytest.mark.unit: Unit tests
• @pytest.mark.integration: Integration tests
• @pytest.mark.api: API tests
• @pytest.mark.rag: RAG-specific tests
• @pytest.mark.embeddings: Embedding-specific tests

Running Tests

Command Line

# Run all tests
pytest tests/

# Run specific test file
pytest tests/test_sqlite_manager.py

# Run tests by marker
pytest -m unit tests/
pytest -m integration tests/
pytest -m api tests/

# Run tests with coverage
pytest --cov=app tests/

Continuous Integration

The tests are designed to run in CI/CD environments:

1. Database Setup: Tests use temporary databases
2. Service Mocking: External services are mocked when needed
3. Isolation: Each test runs in isolation
4. Cleanup: Resources are cleaned up after each test

Coverage Gaps Addressed

The new test suites address the following gaps in the original test coverage:

1. Missing Component Tests: Added tests for all major components
2. Error Scenarios: Comprehensive error handling and edge cases
3. Integration Points: End-to-end testing of component interactions
4. Configuration Testing: Full validation of configuration management
5. Real-time Features: Testing of conversation watching and file monitoring

Future Test Enhancements

Potential areas for future test enhancement:

1. Performance Testing: Load testing and performance benchmarks
2. Security Testing: Authentication and authorization testing
3. Browser Testing: Frontend integration testing
4. Multi-user Testing: Concurrent user scenarios
5. Disaster Recovery: Data backup and recovery testing
