SEC-005: No Singleton Thread-Safety Tests **Status:** UNIMPLEMENTED **Tests Needed:** 4 **Time:** 1.5h **Risk:** Memory leaks, crashes under concurrency ```python # Missing: test_concurrent_get_config_returns_same_instance() # Missing: test_concurrent_get_pool_returns_same_instance() ``` ### 2. SEC-003: No Resource Authorization Tests **Status:** UNIMPLEMENTED **Tests Needed:** 3 **Time:** 1h **Risk:** Future auth bugs, accidental per-user filtering ```python # Missing: test_scout_resource_has_no_user_parameter() # Missing: test_config_has_no_user_filtering() ``` ### 3. P0-4: Output Size Limit Not Tested **Status:** CODE EXISTS, NO TESTS **Tests Needed:** 5 **Time:** 1.5h **Risk:** OOM attacks, memory exhaustion ```python # Missing: test_cat_file_truncates_at_max_size() # Missing: test_max_file_size_configurable() ``` ### 4. P1-1: SSH Timeout Not Tested **Status:** CODE EXISTS, NO TESTS **Tests Needed:** 4 **Time:** 1.5h **Risk:** Hanging commands, resource exhaustion ```python # Missing: test_run_command_passes_timeout() # Missing: test_timeout_prevents_hanging_commands() ``` --- ## Test Files to Create | File | Lines | Tests | Time | |------|-------|-------|------| | `tests/test_singleton_safety.py` | 60 | 4 | 1.5h | | `tests/test_authorization.py` | 30 | 3 | 1h | | `tests/test_output_limits.py` | 50 | 5 | 1.5h | | `tests/test_ssh_timeout.py` | 40 | 4 | 1.5h | | `tests/test_singleton_implementation.py` | 25 | 3 | 0.5h | | **TOTAL** | **205** | **19** | **6h** | --- ## Current Test Inventory ``` Total Tests: 148 ├── Unit: 85 (57%) ✓ Good ├── Integration: 35 (24%) ✓ Good ├── Performance: 20 (14%) ⚓ Partial └── Specialized: 8 (5%) ✓ Good Coverage: 65-75% (estimated) ⚠ Target: 85%+ Gap: 10-20% ``` --- ## Module Coverage (Estimated) | Module | Coverage | Status | |--------|----------|--------| | `utils/` | 85-90% | ✓ | | `models/` | 80-90% | ✓ | | `middleware/` | 75-85% | ⚠ | | `services/` | 70-80% | ⚠ | | `tools/` | 60-70% | ✗ | | `resources/` | 50-60% | ✗ | --- ## Run Tests ```bash # All tests pytest tests/ -v # By category pytest tests/ -m security -v pytest tests/ -m performance -v # With coverage pytest tests/ --cov=scout_mcp --cov-report=term-missing # Phase 1 tests (when created) pytest tests/test_singleton*.py tests/test_authorization.py \ tests/test_output_limits.py tests/test_ssh_timeout.py -v ``` --- ## Security Requirements Checklist | Req | Requirement | Tests | Status | |-----|-------------|-------|--------| | SEC-001 | Auth disabled by default | ✓ 5 | ✓ PASS | | SEC-002 | Bind to 0.0.0.0 | ✗ 0 | ✗ FAIL | | SEC-003 | No resource ACLs | ✗ 0 | ✗ FAIL | | SEC-004 | No audit logging | ✗ 0 | ✗ FAIL | | SEC-005 | Singleton thread-safe | ✗ 0 | ✗ FAIL | | SEC-007 | Health endpoint bypass | ✓ 1 | ✓ PASS | **Score:** 2/6 (33%) --- ## Performance Requirements Checklist | Req | Requirement | Tests | Target | Status | |-----|-------------|-------|--------|--------| | P0-4 | Output size limit | ✗ 0 | 1MB | ✗ FAIL | | P1-1 | SSH timeout | ✗ 0 | 30s | ✗ FAIL | | P2-1 | LRU eviction | ✓ 7 | 100 | ✓ PASS | | P2-2 | Per-host locking | ✓ 8 | 10-50x | ✓ PASS | **Score:** 2/4 (50%) --- ## Implementation Priority ### 🔴 CRITICAL (This Week) 1.
