@Wulian233

considering how pyhton imports work, You might have to modify the files that run on import or any references to load_module. This will be a really daunting task for you :( sorry!

This PR seems sound, however I'll approve it after stanfromireland and hugovk resolve their conversation, because I am not sure either if it should or shouldn't be in the devguide either :)

There is some additional sys.path manipulation added to the test case that doesn't look like it should be necessary.

Otherwise this looks good to me.

That's necessary. If these two lines are removed, the test will fail (p1)

with a ModuleNotFoundError because the modules cannot be found. If they are added back, the test passes. We need to make sure Python can find them, which maybe is the negative effect of removing load_module? I'm not an expert for this, and I don't know the underlying reasons for them, sorry

And sys.path.insert is also used in many other places in this file, for example:

@Wulian233 You're right, the importlib.import_module lines were previously only passing because the prior zi.load_module call had left sys.modules["TESTPACK"] populated.

Given that, it makes sense to keep the path manipulation additions, but move them as far down in their respective test cases as possible to still let the everything pass (which should be just before the importlib.import_module line in each case, since the direct instantiation shouldn't care if the zip archive is on sys.path or not, while importlib.import_module does care).
