# E2E Integration Test - Quick Reference ## Test File **Location:** `/home/user/shannon-mcp/tests/test_e2e_integration.py` ## Quick Stats - **Total Lines:** 660 - **Test Functions:** 12 - **Test Classes:** 2 - **Fixtures:** 4 ## Run Commands ### Run All E2E Tests ```bash poetry run pytest tests/test_e2e_integration.py -v ``` ### Run Single Test ```bash poetry run pytest tests/test_e2e_integration.py::TestE2EIntegration::test_01_server_initialization -v ``` ### Run with Coverage ```bash poetry run pytest tests/test_e2e_integration.py --cov=shannon_mcp --cov-report=term-missing ``` ### Run Performance Tests Only ```bash poetry run pytest tests/test_e2e_integration.py::TestE2EIntegrationPerformance -v ``` ## Test Coverage Map | Test # | Name | Coverage Area | Duration | |--------|------|---------------|----------| | 01 | server_initialization | Server startup, manager init | < 0.5s | | 02 | mcp_list_tools | Tool registration, MCP protocol | < 0.3s | | 03 | mcp_list_resources | Resource registration | < 0.3s | | 04 | binary_discovery | Binary manager, discovery | < 0.5s | | 05 | session_lifecycle | Session CRUD, lifecycle | < 0.5s | | 06 | agent_system | Agent registry, task assignment | < 0.5s | | 07 | resource_access | Resource reading | < 0.3s | | 08 | error_handling | Error cases, shutdown | < 0.3s | | 09 | checkpoint_creation | Checkpoint system | < 0.3s | | 10 | concurrent_operations | Concurrency handling | < 0.5s | | 11 | idempotent_initialization | Multiple init calls | < 0.3s | | 12 | initialization_speed | Performance benchmark | < 0.5s | **Total Expected Runtime:** ~5 seconds ## What's Tested ### Core Components ✓ - [x] Server initialization - [x] Manager lifecycle (start/stop) - [x] Configuration loading - [x] Database connections ### MCP Protocol ✓ - [x] list_tools handler (7 tools) - [x] list_resources handler (3 resources) - [x] call_tool handler - [x] read_resource handler ### Binary Management ✓ - [x] Binary discovery - [x] Version detection - [x] Binary validation ### Session Management ✓ - [x] Session creation - [x] Session state transitions - [x] Message sending - [x] Session cancellation - [x] Session listing ### Agent System ✓ - [x] Agent registration (26 agents) - [x] Agent listing with filters - [x] Task assignment - [x] Agent scoring - [x] Metrics tracking ### Resources ✓ - [x] shannon://config - [x] shannon://agents - [x] shannon://sessions ### Advanced Features ✓ - [x] Checkpoint creation - [x] Concurrent operations - [x] Error handling - [x] Graceful shutdown ## What's NOT Tested ### Real Integration - [ ] Real Claude Code binary execution - [ ] Real subprocess streaming - [ ] Real JSONL parsing - [ ] Network operations - [ ] File system hooks ### Performance - [ ] High load (100+ sessions) - [ ] Memory usage patterns - [ ] Long-running sessions - [ ] Large message payloads ### Edge Cases - [ ] Network failures - [ ] Disk full scenarios - [ ] Process crashes - [ ] Resource exhaustion *These are intentionally excluded for test speed and should be covered in separate integration/load tests* ## Mocking Strategy ### Always Mocked ```python ✓ load_config() - Avoid file I/O ✓ setup_notifications() - Avoid external services ✓ Manager.initialize() - Avoid database operations ✓ BinaryManager.discover_binary() - Avoid system scanning ✓ Subprocess execution - Avoid real processes ``` ### Never Mocked ```python ✓ Server class instantiation ✓ Handler registration ✓ Basic Python logic ✓ Data structure operations ``` ## Fixtures Reference ### temp_workspace ```python # Provides: Path to temporary directory # Cleanup: Automatic after test # Use: For creating test files/directories ``` ### mock_claude_binary ```python # Provides: Path to mock executable # Platform: Cross-platform (Unix/Windows) # Use: For binary discovery tests ``` ### test_config ```python # Provides: ShannonConfig object # Managers: All configured with test settings # Use: For server initialization ``` ### mock_binary_info ```python # Provides: BinaryInfo object # Version: "1.0.0" # Use: For session/binary tests ``` ## Common Assertions ### Server State ```python assert server.initialized is True assert server.config is not None assert len(server.managers) == 4 ``` ### Tool Registration ```python assert len(tools) == 7 assert "find_claude_binary" in tool_names ``` ### Session State ```python assert session.state == SessionState.RUNNING assert session.id is not None ``` ### Agent System ```python assert len(agents) == 26 assert assignment.score > 0 ``` ## Debugging Tips ### Test Hangs ```bash # Add timeout poetry run pytest tests/test_e2e_integration.py --timeout=10 ``` ### Mock Not Working ```python # Check patch path with patch('shannon_mcp.server.BinaryManager'): # Correct with patch('BinaryManager'): # Wrong ``` ### Async Issues ```python # Ensure @pytest.mark.asyncio @pytest.mark.asyncio async def test_something(): await something() # Must use await ``` ### Import Errors ```bash # Check PYTHONPATH export PYTHONPATH="${PYTHONPATH}:./src" poetry run pytest tests/test_e2e_integration.py ``` ## Success Indicators When tests pass, you have confidence in: - ✅ Server can start and stop cleanly - ✅ MCP protocol handlers work - ✅ Managers integrate properly - ✅ Binary discovery functions - ✅ Session lifecycle is correct - ✅ Agent system operates - ✅ Resources are accessible - ✅ Errors are handled - ✅ System is performant ## Next Steps After E2E tests pass: 1. Run unit tests: `poetry run pytest tests/` 2. Check coverage: `poetry run pytest --cov` 3. Run integration tests with real binary 4. Perform load testing 5. Test in production-like environment ## Documentation - **Full Summary:** `/home/user/shannon-mcp/tests/E2E_TEST_SUMMARY.md` - **Test Code:** `/home/user/shannon-mcp/tests/test_e2e_integration.py` - **Project Tests:** `/home/user/shannon-mcp/tests/`
