Live-GUI smoke test for the tkinter.filedialog AttributeError regression.
|
|
|
|
On Python installs where the Tcl/Tk runtime is missing, the lazy
|
|
`tkinter.filedialog` import raises AttributeError, which previously
|
|
crashed the Project Settings window and the Add Project button.
|
|
The unit-level test in `test_lazymodule_filedialog_fallback.py`
|
|
deterministically exercises the fallback path; this live test verifies
|
|
the same fix in the actual running app: opening the Project Settings
|
|
window via the Hook API must not produce an AttributeError, and the
|
|
app must remain responsive (proving no crash on attribute resolution).

"""
|
|
Regression: the Project Settings window's render call chain ends
|
|
in `render_projects_panel` → `filedialog.askopenfilename(...)` on
|
|
the "Add Project" click frame. Before the fix, every frame the
|
|
Project Settings window was open on a broken tkinter install would
|
|
log `AttributeError: module 'tkinter' has no attribute 'filedialog'`.
|
|
The fix in `_LazyModule._resolve()` falls back to a `_FiledialogStub`
|
|
that returns empty strings.
|
|
|
|
This test:
|
|
1. Opens the Project Settings window via the Hook API
|
|
2. Waits several render frames
|
|
3. Verifies the window opened (state is reflected back via get_value)
|
|
4. Verifies the app is still responsive (status endpoint returns 200)
|
|
5. Verifies no AttributeError was logged (the bug would print to
|
|
the GUI's stderr, which the live_gui fixture captures to a log)
