VSCode Pytest Discovery Fails With Unhelpful Error

[brettcannon]

Discussed in #22491

^{Originally posted by dylan-at-na November 17, 2023}
PyTest Discovery consistently failing, the error message isn't telling me much. Error messages follow (full log at end of message).

The Python extension has run into an unexpected situation while processing a pytest node during test discovery. Please Please open an issue at: https://github.com/microsoft/vscode-python/issues and paste the following output there.
INTERNALERROR> NotImplementedError: Unexpected pytest node (see printed output).
NotImplementedError: Unexpected pytest node (see printed output).
Exception: pytest discovery failed (exit code 3)

I'm (attempting) to run using poetry. Full log below but additionally I've come across a number of issues which seem to swap around. I'm not sure where to go with the above but I've also come across regular ModuleNotFound import errors during Test Discovery that aren't present when executing a test with PyTest. If anybody is able to advise on that.

hi dylan-at-na, I am going to look into this shortly. Thanks for bringing this up!

[eleanorjboyd]

Hello! It looks like you might not be on the new rewrite of testing. Could you try it there? To try it yourself, you need add this setting to your users settings.json "python.experiments.optInto": ["pythonTestAdapter"].

You can confirm you have the rewrite enabled by setting your log level to "trace" via the command palette and then check for Experiment 'pythonTestAdapter' is active in your python logs.

Let me know if the rewrite fixes your issue. Thanks!

Same error here. After a bunch of hours I finally figured out that it was due to the fact that I opened the project from a symlink directory... a recurrent issue in vscode: https://github.com/search?q=repo%3Amicrosoft%2Fvscode%20symlink&type=issues

[eleanorjboyd]

dylan-at-na, are you using symlinks?

As a note on symlinks I created this issue to consolidate bug reporting related to it: #22658. I have a potential fix but it will need extra time as it is more complicated than originally intended.

[eleanorjboyd]

Hello! I have put together a detailed problem report and proposed solution for symlinks. Please check it out here and contribute any thoughts you may have: #22658
