## Dependencies and Mocks
### Key Fixtures Used
- `mock_mcp_server` - Mock FastMCP server for tool registration
- `reflection_db` - Temporary database for memory tests
- `reflection_db_with_data` - Database pre-populated with test data
- `mock_project_factory` - Creates mock project structures
- `mock_git_repo_factory` - Creates mock git repositories
- `temp_test_dir` - Temporary directory for file operations
### Mocking Strategy
- **Session Manager**: Mocked to avoid full lifecycle initialization
- **Database**: Uses temporary DuckDB databases
- **File System**: Uses pytest's `tmp_path` for isolation
- **Subprocess**: Mocked for UV and git operations
- **Environment**: Patched for consistent test behavior

│ ├── test_mcp/ # NEW: MCP tools tests ⬅️
│ └── test_cli/ # NEW: CLI tests ⬅️
├── integration/ # Integration tests
└── conftest.py # Shared fixtures
```
### Shared Fixtures
All tests use the existing `conftest.py` fixtures:
- `fast_temp_db` - Optimized temporary database
- `mock_project_factory` - Project structure creation
- `mock_mcp_server` - MCP server mocking
- `reset_di_container` - DI container cleanup
- `mock_settings` - Settings mocking

## Maintenance Notes
### Test Updates Needed When:
- Adding new MCP tools → Add test class to `test_mcp/`
- Modifying tool signatures → Update relevant test class
- Adding CLI commands → Add tests to `test_cli/`
- Changing database schema → Update memory tool tests
### Test Health Monitoring
```bash
# Run tests and check for issues
pytest tests/unit/test_mcp/ tests/unit/test_cli/ -v --tb=short
# Check coverage trends
pytest tests/unit/test_mcp/ tests/unit/test_cli/ --cov=session_buddy --cov-report=term-missing
# Run specific failing tests
pytest tests/unit/test_mcp/test_session_tools.py::TestSessionTools::test_start_tool_success -v
```

## Conclusion
Phase 2: MCP Tools Tests is **COMPLETE** with 82 comprehensive unit tests covering session management, memory tools, and CLI commands. The tests provide excellent coverage (70-85%) of the MCP server functionality and ensure reliability of core features.
All tests use proper async handling, mocking strategies, and fixture-based setup for maintainability and reliability.
**Ready for Phase 3: Integration and Performance Testing**
