## Skipped Tests

| Test | Reason |
|------|--------|
| test_ft_n_05_missing_classes_json | Requires separate Docker profile without classes.json |
| test_nft_res_04_service_restart | Requires docker compose restart capability from e2e-runner |

## Test Scenario Coverage

| Category | Scenarios | Tests |
|----------|-----------|-------|
| Positive Functional (FT-P) | 16 | 16 |
| Negative Functional (FT-N) | 8 | 8 (1 skipped) |
| Non-Functional (NFT) | 15 | 14 (1 skipped) |
| **Total** | **39** | **38** |

## Architecture

- **Test framework**: pytest with pytest-timeout, pytest-csv
- **Infrastructure**: Docker Compose with CPU and GPU profiles
- **Mock services**: Flask-based mock-loader (model/media serving) and mock-annotations (annotation recording)
- **Media fixtures**: 6 images, 3 videos, 1 ONNX model, 1 classes.json
- **SSE testing**: Threading-based pattern with sseclient-py
- **Concurrent testing**: concurrent.futures.ThreadPoolExecutor

## Code Review Summary

All batches passed with PASS_WITH_WARNINGS. No Critical or High findings. Key observations:
- Pre-init health test depends on test execution order (acceptable given class-based ordering)
- Weather class labels correctly handle Name(Wint)/Name(Night) suffix convention
- Overlap metric uses containment-style ratio matching production behavior
- SSE tests use proper threaded listener pattern with Event synchronization
