Speaking from memory, I think the whole def test_suite can be removed, except maybe in very special cases. Also in Python 2.7.

Speaking from memory, I think the whole 'def test_suite' can be removed, except maybe in very special cases. Also in Python 2.7.

It depends: zope.testrunner has an auto-detect feature for unittest subclasses, but we still need test_suite for doctests. So in most of the cases test_suite could be removed.

This issue should have been fixed by running meta/drop-legacy-python.py as it runs pyupgrade.
