285 total tests
├── 233 unit tests (81.8%)
├── 16 e2e tests (5.6%)
├── 18 integration tests (6.3%)
├── 9 skipped (optional deps)
└── 9 physical tests (3.2%)
```

|-------|--------|----------------|
| **TDD violations noted** | Medium | Document retroactive TDD tests |
| **Some tests too large** | Low | Split complex tests |
| **Missing property tests** | Low | Add hypothesis for edge cases |

### 2. TDD Compliance (75/100)

#### Documented Process ✅
- TDD_WORKFLOW.md exists
- Clear Red-Green-Refactor cycle
- Commit message conventions
- Examples provided

#### Violations Found ⚠️

| File | Issue | Status |
|------|-------|--------|

| `ros2_connector.py` | Implemented before tests | ✅ Fixed (tests added) |
| `grpc_transport.py` | Implemented before tests | ✅ Fixed (added TDD tests retroactively) |

**Retroactive TDD Tests Added:**
- `test_ros1_connector_tdd.py` — 30+ tests
- `test_grpc_transport_tdd.py` — 35+ tests

#### Recommendations 🟡

1. **Pre-commit Hook** — Block commits without tests for new features
