Hey @FelixBenning, I have been encountering the same issue and this solution: https://github.com/microsoft/vscode-python/issues/14579#issuecomment-725837711 solved it.

Adding an __init__.py in the test suite folder also seemed to “fix” this particular issue for me without requiring a downgrade. You really shouldn’t need it there for the test suite to work though thus the cautious use of the word fix.

Even though that shouldn’t be needed as running pytest from the terminal works fine. Seems it’s a pythonpath issue with vscode.

Probably related to: https://github.com/microsoft/vscode-python/issues/14570 and https://github.com/microsoft/vscode-python/pull/16274

Your issue isn’t related to #14570 nor #16274, since it isn’t using pyvsc-run-isolated.py. Sounds like it’s more a case of https://github.com/microsoft/vscode-python/issues/15062, which, incidentally, has a similar workaround.

Feel free to upvote #15062 to help us prioritize it! In the meantime, I will close it as a duplicate of #15062.
