Importing module of pytest plugin triggers a PluginValidationError: unknown hook #3775
Description
I use Pytest 3.6.4.
When I import from pytest_selenium import pytest_selenium and then use pytest_selenium in conftest.py I get PluginValidationError: unknown hook.
This error has been also encountered by some users:
- jantman/biweeklybudget@8184571
- Unknown hook with latest pytest pytest-django#607
- shawnbrown/datatest@5ad76f3
How is one expected to deal with it?
