Testing could fail with pytest-randomly

[mtelka]

During testing of 3.5.1 I noticed that few tests sometimes fails when I test with the pytest-randomly plugin. Without the pytest-randomly plugin all tests always pass.

Here are typical failures:

    def test_method_result_is_path(func_path: str) -> None:

We don't support running with that plugin. That being said feel free to add a PR to fix this.
