1.10: pytest is failing

[kloczek]

I'm trying to package your module as an rpm package. So I'm using the typical build, install and test cycle used on building packages from non-root account.

• "setup.py build"
• "setup.py install --root </install/prefix>"
• "pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

May I ask for help because few units are failing:

This is some kind of problem with how you're invoking pytest -- it's going into the mode where it tries to find individual test modules, instead of the mode where it imports a whole test package. I always find this part of pytest super confusing, and I don't know how to fix it off-hand. Maybe try passing --pyargs async_generator?

[kloczek]

Yep that works. Just learn something new :)

+ /usr/bin/pytest -ra --pyargs async_generator
