Django 2.0 unit test not running due to AppRegistryNotReady - django

Question

I built a very simple Django application to try unit testing. I can run a test without any problem when not importing any Django model, like:
import os
from django.test import TestCase
class FirstTest(TestCase):
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "testje.settings")
def test_First(self):
a = 1
self.assertEqual(1, a)
I'm running Django 2.0.1. Now when I'm trying to import a model like:
import os
from django.test import TestCase
from polls.models import Question
class FirstTest(TestCase):
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "testje.settings")
def test_First(self):
a = 1
self.assertEqual(1, a)
it will fail with the following stack trace:
Testing started at 16:46 ...

As you can see I'm running from PyCharm CE 9the latest version). I have been looking for answers and trying many things but so far without any luck. Any idea what I'm missing here (probably something very simple)?
