* tests: ship public-api surface drift detector + wire into Core matrix Companion to tests/test_import_fixes_drift.py (PR #5414): that file catches drift in THIRD-PARTY libs (transformers / trl / triton / peft / vllm / torchcodec / xformers); this file catches drift in unsloth's OWN public-surface API -- the top-9 classmethods + symbols that unslothai/notebooks calls at ~2000 cumulative sites. Closes the gap where a refactor on this repo (e.g. renaming FastLanguageModel.from_pretrained -> .load) would pass unsloth CI green and surface only on the next unslothai/notebooks CI run, or worse, on a user's Colab crash report. Coverage (call-site counts measured against unslothai/notebooks main): test_fast_language_model_class_present test_fast_language_model_from_pretrained_kwargs 506 sites test_fast_language_model_get_peft_model_kwargs 304 sites test_fast_language_model_for_inference_callable 370 sites test_fast_vision_model_class_and_methods (4 methods) test_fast_vision_model_get_peft_model_vision_kwargs (4 kwargs) test_fast_model_class_and_methods (2 methods) test_fast_model_from_pretrained_kwargs 103 sites test_is_bf16_supported_or_alias_callable 48 + 8 sites Each test asserts the healthy public shape via inspect.signature; on regression fires pytest.fail("DRIFT DETECTED: ...") -- never pytest.skip -- so the Core matrix cell goes red. Mirrors the same skeleton used by tests/test_import_fixes_drift.py. Wired as a new step in consolidated-tests-ci.yml right after the import_fixes drift step, inside every Core matrix cell. Local verification on transformers 4.57.6 + unsloth main: pytest tests/test_public_api_surface.py -v -> 9 passed in 0.02s * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> |
