No lock and no owed slot while holds.covers("diet") is true; slots
inside a hold are excused; an open lock lifts within 30 s of a hold
starting. Fail closed (normal rules) if holds is missing or raises.
Pin holds-v0.1.0; bump coverage 7.17.1.

"""Shared fixtures for diet_guard tests.
|
|
|
|
Three safety nets run for every test:
|
|
|
|
* ``_isolate_state`` redirects the food log, sealed budget, gate lock, and
|
|
sync token into ``tmp_path`` so a test can never read or clobber the real
|
|
``~/.local/share`` or ``~/.config/diet_guard``.
|
|
* ``_block_real_tk`` swaps ``tk`` and the ``GateRoot`` window class inside
|
|
``_gatelock`` for mocks, so no test can open a real fullscreen window or grab
|
|
the keyboard even if it forgets to.
|
|
* ``_block_real_vt`` makes ``gatelock``'s VT-switch disable a no-op, so a
|
|
prod-mode (``demo_mode=False``) gate built in a test never runs a real
|
|
``setxkbmap`` against the live X session.
|
|
|
|
The ``gate`` fixture and its supporting fakes (``FakeEntry``, ``_FAKE_TK``, ...)
|
|
build a demo :class:`~diet_guard._gatelock.MealGate` whose widgets
|
|
are functional in-memory stand-ins, shared by ``test_gatelock.py`` and
|
|
``test_gatelock_mealflow.py``.
