When in doubt, **add the parent module prefix** — a slightly longer name is always better than an ambiguous one. + +### Rules (applied in order) + +1. **Generic / short leaf names** (e.g., `audio.py`, `video.py`, `tbo.py`, `storage.py`, `config.py`) + → **Always** prefix with the parent module (or test directory name): `test__.py` + - `fastdeploy/multimodal/audio.py` → `tests/multimodal/test_multimodal_audio.py` + - `fastdeploy/multimodal/video.py` → `tests/multimodal/test_multimodal_video.py` + - `fastdeploy/worker/tbo.py` → `tests/worker/test_worker_tbo.py` + - `fastdeploy/scheduler/storage.py` → `tests/scheduler/test_scheduler_storage.py` + - `fastdeploy/input/image_processors/qwen3_processor.py` → `tests/input/test_image_qwen3_processor.py` + + > **How to judge "generic"**: If the leaf name could plausibly exist in multiple packages (e.g., `utils.py`, `config.py`, `base.py`, single-word names), it is generic. + +2. **Leaf name == parent directory name** (e.g., `file_store/file_store.py`, `mooncake_store/mooncake_store.py`) + → Use `test_.py` directly. The repetition already provides context. + - `transfer_factory/file_store/file_store.py` → `test_file_store.py` + - `transfer_factory/mooncake_store/mooncake_store.py` → `test_mooncake_store.py` + +3. **Leaf name is already specific and self-descriptive** (multi-word compound names that are unique across the project) + → Use `test_.py` directly. No prefix needed. + - `transfer_factory/ipc_cache_transfer.py` → `test_ipc_cache_transfer.py` + - `layers/attention/block_multihead_attn_backend.py` → `test_block_multihead_attn_backend.py` + - `layers/attention/dsa_attention_backend.py` → `test_dsa_attention_backend.py` + + > **How to judge "self-descriptive"**: The name contains 3+ words or includes the module domain (e.g., `ipc_cache_transfer` clearly belongs to cache transfer). + +4. **Leaf name != parent directory and is not fully self-descriptive** + → Prefix with the parent directory name: `test__.py` + - `mooncake_store/attention_store.py` → `test_mooncake_attention_store.py` + - `input/utils/render_timestamp.py` → `test_input_utils_render_timestamp.py` + +5. **Collision check**: Before finalizing the name, verify no existing file in the target `tests/` subdirectory has the same name. If a collision is found, add more path components as prefix until unique. + +### Consistency Reference + +Check existing test files in the same `tests/` subdirectory and **follow the dominant pattern**: +- `tests/worker/` uses `test_worker_*.py` prefix (e.g., `test_worker_process.py`, `test_worker_eplb.py`) +- `tests/multimodal/` uses `test_multimodal_*.py` prefix (e.g., `test_multimodal_utils.py`, `test_multimodal_audio.py`) +- `tests/model_executor/` does NOT prefix (names are already specific: `test_gpt_oss.py`, `test_entropy_utils.py`) + +When a directory has an established prefix pattern, always follow it for new files. + +### Placement + +- The test file goes into the `tests/` subdirectory matching the **top-level source package** (e.g., source in `fastdeploy/cache_manager/...` → test in `tests/cache_manager/`). +- Only create deeper subdirectories if one already exists in `tests/` (e.g., `tests/cache_manager/v1/`). + +--- + +## GPU Execution Environment & Coverage Expectations + +Tests are always executed on GPU machines (2x NVIDIA H20). When writing unit tests, keep in mind: + +1. **Hardware-dependent code paths may be unreachable** — Some branches depend on specific hardware conditions that cannot be easily simulated in tests: + - NUMA topology detection (e.g., `nvidia-smi topo`, `/sys/class/nvidia-gpu/`, `/sys/bus/pci/devices/`) + - Multi-node / RDMA communication paths + - Specific GPU architecture features (e.g., SM version checks) + - Device memory capacity checks that vary per hardware + +2. **Coverage gaps from hardware-specific paths are acceptable** — Do not force coverage of code that genuinely requires hardware conditions you cannot mock cleanly. The 80% diff coverage threshold accounts for this; it is fine to leave hardware-gated branches uncovered as long as the logical/mockable portions are well-tested. + +3. **Mock what you can, skip what you can't** — For functions that mix logic with hardware access (e.g., `_get_numa_node_for_gpu`), mock the system calls (`subprocess.run`, `os.path.exists`, `glob.glob`, file reads) to test the parsing logic. Don't try to cover paths that are purely pass-through to hardware APIs with no testable logic. + +4. **Attribute access patterns** — The `CacheTransferManager` and similar objects may not have all methods (like `start()`/`stop()`) as static attributes. When mocking such methods, use `patch.object(..., create=True)` or mock at the `CacheController` level instead. + +--- + +## Codestyle Check + +After writing or modifying test files, run pre-commit to ensure the code passes CI style checks: + +```bash +# Install pre-commit if not available (ref: tools/codestyle/pre_commit.sh) +pip install pre-commit==4.2.0 clang-format==13.0.0 + +# Check code style on the new/modified test files +pre-commit run --files tests/path/to/test_xxx.py +``` + +Fix any reported issues before declaring the test complete. + +--- + +## Checklist +Before submitting a test: + +- [ ] File name follows the naming convention above (leaf-name based with parent prefix when needed for disambiguation) +- [ ] Test class follows `Test` pattern +- [ ] Test methods follow `test_` pattern +- [ ] Uses pytest (or unittest) +- [ ] Located in appropriate `tests/` subdirectory +- [ ] Service tests use a session-scoped fixture to start/stop the server subprocess; see `tests/e2e/` for reference patterns +- [ ] Any test referencing port variables or TP config will run sequentially in CI — this includes `tensor_parallel_size=1` +- [ ] Cleans up resources: server subprocess terminated with `os.killpg` + `clean_ports()` in fixture teardown +- [ ] Has `if __name__ == "__main__": pytest.main(...)` or `unittest.main()` for local execution +- [ ] Does not exceed 600s timeout per test file +- [ ] Maintains or improves coverage (80% diff threshold for PRs) +- [ ] Hardware-dependent paths that cannot be mocked are acceptable coverage gaps +- [ ] Passes `pre-commit run --files` code style check (black, isort, flake8) diff --git a/fastdeploy/entrypoints/openai/test_openai.py b/fastdeploy/entrypoints/openai/test_openai.py deleted file mode 100644 index 3b56b2c225d..00000000000 --- a/fastdeploy/entrypoints/openai/test_openai.py +++ /dev/null @@ -1,80 +0,0 @@ -""" -# Copyright (c) 2025 PaddlePaddle Authors.
