Description

We can tackle test isolation issues in future work by adding a pytest plugin or some other solution for shuffling test cases.

Originally posted by @jacobtylerwalls in https://github.com/pylint-dev/pylint/issues/9041#issuecomment-1732605038

I'm familiar with the Django test runner's --shuffle option, but perhaps we can evaluate pytest-random-order or other plugins.

Contributor guide

Research direction
Evaluate pytest random order plugin or implement shuffle similar to Django's test runner. Consider edge cases and conflicts with existing test ordering.
