[issue16662] load_tests not invoked in package/__init__.py

[Anthony Sottile]

I have a hunch that this fix here may be causing this: https://github.com/spotify/dh-virtualenv/issues/148

Minimally:

echo 'from setuptools import setup; setup(name="demo")' > setup.py
echo 'import pytest' > tests/__init__.py

$ python setup.py test
running test
running egg_info
writing dependency_links to demo.egg-info/dependency_links.txt
writing demo.egg-info/PKG-INFO
writing top-level names to demo.egg-info/top_level.txt
reading manifest file 'demo.egg-info/SOURCES.txt'
writing manifest file 'demo.egg-info/SOURCES.txt'
running build_ext

OK


$ python3.5 setup.py test
running test
