Description

opened on Jul 17, 2024

I typically have several projects open in VS Code, i.e. in the current workspace. They can be Python (hatch), Java (Maven), GitLab CI/CD Components etc. VS Code Python sometimes have issues with pytest discovery in non-Python projects which results in me not being able to use Test Explorer to run/debug tests.

A typical error message looks like this:

2024-07-17 14:18:20.859 [error] pytest test discovery error for workspace: /home/u30576/dev/clones/sysdev/devops/cicd-components/python

    Can you include more logs and either an example smaller project or the structure of your project where you are experiencing this issue with. Thanks

    Sure.

    To reproduce what I have below:

    1. start code without any projects
    2. https://github.com/luftfartsverket/reqstool-java-annotations.git
    3. add https://github.com/luftfartsverket/reqstool-client.git

    image

    What logs do you want? Python Test Log provided below.

    I would not be surprised if there is an issue with environments (which I filed an issue for as well) due to the error message

    🤖 Thanks for the detailed reproduction, and apologies that this remained pending after it was reopened. Testing and environment selection have changed substantially since the 2024 report; could you confirm whether the same two-repository workspace still fails on the latest Python and Python Environments extensions, and attach the current Python Test Log plus Python: Report Issue output if it does? In particular, please note whether the non-Python folder's failure still prevents tests from the Python project appearing or running. We use the info-needed label for this confirmation, and issues with that label automatically close after 30 days without a reply.
