Support pytest test discovery in monorepo setup with multipe tests/conftest.py

[atinary-bvollmer]

I'm currently working in a python monorepo setup where we have multiple libraries and projects. They each have their own tests folders.

The problem I'm facing is that the test discovery of VSCode fails due to an ImportPathMismatchError error as pytest does not allow for multiple tests/conftest.py path to be used.

The cleanest solution I found so far is to rename the tests folders to NAME_tests to avoid the duplication but it does feel weird and hacky.

Fixing this would help further making VSCode a tool that works well in a monorepo setup.

Some related issues:

• ImportPathMismatchError from subprojects with same test folder structure
• Enable multiple test suites and test configurations in the Test UI
• pytest test discovery tries to import conftest.py from other projects
• Proposal: Enable separate configs per run/discovery/debug/coverage with testing
