Since pytest 3.1.0 (currently at 3.2.3) pytest-bdd breaks in cookiecutter-qa with:
_pytest.vendored_packages.pluggy.PluginValidationError: unknown hook 'pytest_bdd' in plugin <module 'project_qa.tests.functional.conftest' (<_pytest.assertion.rewrite.AssertionRewritingHook object at 0x7f035b2d4f28>)>
Up to version 3.0.7 this does not happen.
