"""Hermetic tests for ``utils.filedialogs``.
|
|
|
|
These tests never open a real dialog: every tkinter touchpoint is mocked,
|
|
so they run headless and even on machines without Tk system libraries
|
|
(e.g. the CI runner, where ``import tkinter`` fails on a missing
|
|
``libtk8.6.so``). ``conftest.py`` registers a tkinter stub in that case,
|
|
so ``utils.filedialogs`` can be imported at all.
|
|
|
|
For tests that open a real dialog, see ``test_filedialogs_live.py``
|
|
(marker ``live``, excluded from the default run).
