Recently pylint has started to complain about: No name 'fs_helper' in module 'tests' (no-name-in-module) Due to: from tests import fs_helper However, we have: test/py/tests/fs_helper.py And since we do not want to add a dummy test/py/tests/__init__.py to silence this warning we instead just disable it as needed.
