What is the problem?
Current Ray docs as of 2021-05-16 at https://docs.ray.io/en/master/getting-involved.html#testing suggest running the unit test suite via:
pytest ray/python/ray/tests/
However, then you run into issues like #13374 , where different tests cross-contaminate the environment. The solution mentioned there is to run tests using bazel, but using bazel to run Python tests (particularly for a Python-only setup as in https://docs.ray.io/en/master/development.html#building-ray-python-only ) isn't reflected in the contributor docs.
