I'm getting the following error trying to run the tests:

django.core.exceptions.ImproperlyConfigured: 'django.contrib.gis.db.backends.postgis' isn't an available database backend or couldn't be imported. Check the above exception. To use one of the built-in backends, use 'django.db.backends.XXX', where XXX is one of:
    'mysql', 'oracle', 'postgresql', 'sqlite3'

It looks like the test settings need to be updated.

It looks like the test settings need to be updated.

Though I see that the test action is succeeding. Must be something on my end then...

Yep, I needed to set an environment variable to make sure it could find homebrew libs. Tests are succeeding now.

Nice work on this!
