[issue27918] Running test suites without gui but still having windows flash

Terry J. Reedy added the comment: This issue only addresses and fixes the 1 flash per process from test.support.is_gui_available. I separately added root.withdraw to IDLE tests in #27922, to stop their flashes. Doing the same for tkinter tests would be a third issue. I believe it would be e

Martin Panter added the comment: Xiang’s second patch looks okay to me. The flashes occasionally annoy me with X windows if I am doing something else and have the Python tests running in the background. I understand deferring the _is_gui_available() call will fix the main problem, and the wit

Terry J. Reedy added the comment: I completely agree that we should not check that gui works unless and until it is requested. Can you write a patch to do the switch? My point was that even when I request gui, I still don't want to see the flash. I do TDD for test files as well as app file

Xiang Zhang added the comment: > they both use test.support.import_module with no reason Sorry, this is a typo. I meant to say "they both use test.support.requires". There should be *no* "no reason" and it's "requires" not "import_module". Sorry to confuse you. Staying late in night fools my b

[issue27918] Running test suites without gui but still having windows flash

Terry J. Reedy added the comment: Some time ago I tried adding 'root.withdraw' to idle_test files that used tkinter to stop the widget flashing. This never worked completely. Now I know why -- it was the test.support import. Knowing this now, I opened #27922 to add 'root.withdraw' where els

Terry J. Reedy added the comment: To my surprise, "python -m test test_idle" gives a single flash in Windows. #22770 modified /Lib/test/support/__init__.py and added the creation and packing of a Label. Those two lines are gone in repository 3.6 but the flash is still there, I added root.wit

[issue27918] Running test suites without gui but still having windows flash

New submission from Xiang Zhang: When I run test suites I find something interesting. Even if I don't enable gui resource there are still windows flashing. The two tests are test_idle and test_tk. I think the root cause is that they both use test.support.import_module with no reason and then r
