The suite hadn't run green since the routes refactor: - test_profile_duplicate_names.py imported the pre-refactor module layout and broke collection; now imports backend.services.profiles - tests/conftest.py puts the repo root and backend dir on sys.path so files collect standalone instead of depending on run order - test_cors.py tested a hand-copied mirror of the origin list that had drifted from app.py (missing http://tauri.localhost); it now builds the app via the real create_app() factory - test_progress.py simulated a 1KB download, below the tracker's 1MB reporting threshold; simulation raised to 5MB - slow/timeout markers registered in pyproject Ruff: ~900 violations auto-fixed (typing modernization, import sorting, unused imports, whitespace). The remaining rules are baselined in pyproject.toml with per-rule counts to burn down, plus per-file carve-outs for deliberate env-before-import ordering. ruff check is now clean; suite is 134 passed, 2 skipped.

"""

|
Unit tests for the ``force_offline_if_cached`` helper.
|
|
|
|
Verifies that the helper mutates the cached module constants in
|
|
``huggingface_hub.constants`` and ``transformers.utils.hub`` — not just
|
|
``os.environ`` — and that concurrent users are refcount-coordinated so
|
|
one thread's exit can't strip another thread's offline protection.
|
|
|
|
NOTE: These tests mutate process-global state in ``huggingface_hub.constants``
|
|
and ``transformers.utils.hub``. They are not safe under cross-process
|
|
parallelism (e.g. ``pytest-xdist`` with ``--dist=loadfile``/``loadscope``);
|
|
run this file serially.
