I've seen this question come up on stack overflow, can't recall I've
seen a completely satisfactory answer.
I would suggest, however, that doing the testing you're considering
should be written as unit tests. You can invoke unit tests from inside
the program by adding something like this (I'm a pytest fan, but it
could be unittest as well of course):
import pytest
# your code here
if __name__ == "__main__":
pytest.main(["--capture=sys", "name-of-unittest-script.py"])
You can write your own argument array by fiddling with sys.argv; pytest
also provides a mechansim for injecting arguments (I think it's called
pytest_addoption).
The somewhat hacky way for a script to find out that it's running inside
IDLE (note: every time someone asks how to do this, a crowd of people
pop up and say "you don't want to be doing that". But enabling a
testing scenario might actually be a time you want to?):
import sys
if "idlelib" in sys.modules:
print("We're running in IDLE")
These aren't really an answer to what you're asking for, but maybe some
tools you might use to think further about the problem?
