"""Make the test suite runnable on machines without Tk system libraries.
|
|
|
|
``utils.filedialogs`` imports tkinter at module level, and the CI runner
|
|
lacks the Tk shared libraries (``import tkinter`` fails on a missing
|
|
``libtk8.6.so``). Since pytest imports every test module at collection
|
|
time — including the deselected ``test_filedialogs_live.py`` — a minimal
|
|
stub is registered in ``sys.modules`` here, before any test module is
|
|
imported, whenever tkinter is not importable.
|
|
|
|
The hermetic tests in ``test_filedialogs.py`` mock every tkinter
|
|
touchpoint anyway, so the stub is never actually used.
