Getting "pytest test discovery error for workspace" when having multiple projects in workspace

[jimisola]

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

[lfvjimisola]

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

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
