Trouble running tests

I'm sure this has something to do with some configuration, but I'm having trouble running a basic django test in pycharm.

If, from inside the root of my project, I run: python3 managepy test, my tests run fine.

If, however, I try to run my tests by using Tools|Run Manage.py task, I get this:
App registry isn't ready yet.…

If I run the command that pycharm tried to run:

/usr/local/bin/python3 /Applications/PyCharm.app/helpers/pycharm/django_test_manage.py test /Users/mrankin/src/tddproject/superlists
, I get this:

I've tried a bunch of setting changes, but I feel like I'm just guessing at this point.
