vscode-python: VS Code python unittest fails to import modules outside tests folder during debug
Type: Bug
Since earlier this month, attempting to debug Python unittest tests in existing and new projects fails with an error similar to
ModuleNotFoundError: No module named '<file or folder name>'
for any test file trying to import something outside of the tests folder.
A basic project based on guidance in Testing Python in Visual Studio Code can be cloned from https://github.com/cfframe/PythonBasicTest.
Tests will run using the gui, but debugging a test generates this error in the DEBUG CONSOLE:
E
======================================================================
ERROR: test_unittest (unittest.loader._FailedTest)

ImportError: Failed to import test module: test_unittest

I have no similar problems with PyCharm on the same projects.

Thank you for your issue report. We are looking into this now! In the meantime, you are likely on the new testing rewrite and this is why you saw a change in behavior since we just moved to this experiment to a larger group of people receiving it. You can opt out of the rewrite as I get this fix in by setting this in your user settings:
"python.experiments.optOutFrom": ["pythonTestAdapter"],. If this doesn’t work let me know as this will mean it is a different issue. Thank you and I will send updates in this thread as I get a fix in.For those of you coming across this error while in a docker container, You have to set this in your docker container’s settings:
Settings -> Remote[...Container...] -> add the settingThis happened out of the blue for me. And I was pulling my hair out for few days. Thank for your help everyone.
