test_base ExecTestCase, "wxExecute", "[exec]" fails on Windows 11 (Issue #25825)

[Richard Thomson]

LegalizeAdulthood created an issue (wxWidgets/wxWidgets#25825)

Description

Bug description:

Running test_base on Windows 11 fails the wxExecute and wxProcess related tests because mspaint is not in the path. mspaint on Windows 11 is in %LOCALAPPDATA%\Microsoft\Apps which may not be in the user's path (it wasn't in mine) instead of in the system directory like it was on previous versions of windows and that can cause these tests to fail.

Expected vs observed behaviour:

It's probably better to control the program being run by building one in wxwidgets itself to use for the test. Then the tests wouldn't be dependent on the environment and the path to the wxwidgets built test program can be obtained with a CMake configure_file

To Reproduce:

1. Make sure mspaint is not in your path, e.g. where mspaint says INFO: Could not find files for the given **pattern(s).**
2. Run test_base
3. wxExecute and wxProcess related tests that use ASYNC_COMMAND in tests\exec\exec.cpp will fail

Thanks for reporting this. If there is some other command we could use which is still in PATH, I'd just use it instead for simplicity... Note that we can't use Notepad (see #23365).

Yeah, I tried hacking it to use notepad and saw the same issue.

I have run where $path:*.exe and there don't see be many suitable candidates (i.e., Win32 apps available on all supported Windows versions) these days.

AFAICT, we need only to (a) launch and (b) kill this process, so no interaction is needed.

So, what about charmap.exe? There is also msinfo32.exe.

BTW, I do have the local app data folder in the PATH on Windows 11 Pro 24H2.
