Problem:

After this PR here: #1441, I noticed CI failure here:

This happened because pytest depends on pytest-xdist, and pytest-xdist depends on pytest-forked, and pytest-forked depends on py, and after I updated pytest to 9.0.3, it is no longer compatible with the old pytest-xdist:

Also based on the information here and here, it seems like py package is a legacy package that is in maintainance mode.

Solution:

Based on the changelog here, we could update pytest-xdist to a version 3.0.2 and higher.

Pull request overview

This PR updates the project’s test dependency set to resolve a CI failure caused by an older pytest-xdist release being incompatible with pytest 9.0.3, eliminating the legacy pytest-forked → py dependency chain that triggered ModuleNotFoundError: No module named 'py.log' in CI.

Changes:

• Bump pytest-xdist[psutil] constraint in setup.cfg to >=3.6.0,<4.0 for test/dev extras.
• Re-lock dependencies in Pipfile.lock, updating pytest-xdist to 3.8.0 and removing pytest-forked / py from the lock.
