Terry J. Reedy <[email protected]> added the comment:
As I reported on related #31761, importing autotest on Windows 10 has 3 errors
with Python's shell and 4 with IDLE's, with two of those the same as the python
shell failures.
IDLE can be detected in at least two ways.
>>> import sys; 'idlelib.run' in sys.modules
True
>>> type(sys.stdout).__name__ == 'PseudoOutputFile'
True
'test.autotest' in sys.modules" would detect that test.autotest is being run,
whether in a Python or IDLE shell.
Running test.__main__ from an editor results in screwy behavior. Running just
'import test.autotest' instead gives the same result. I expected at least the
latter to have the same result as when run in the shell. Wrong.
First, there is an additional test failure.

Next, the tests run normallu up to

Then, while running test_configparser, the user process crashes, IDLE restarts
a new user process, and the test suite restarts (in the IDLE process?) from the
beginning, sending output to the console, not IDLE, and running each test 5
times. This all is repeatable. The following is the initial part of the
console output.

I said 'crash' because the run process catches SystemExit.
>>> raise SystemExit
>>>
I have ocassionally encountered unexpected restarts before, but never, that I
remember, so easily repeatable.
