Django Unit Tests doesn't run in Visual Studio Test Explorer

Question

I'm trying to implement my Django (1.11.7, Python 3.6) unit testing in Visual Studio. When I run them in my terminal (python manage.py test) they run fine, while when executing from the VS Test Explorer it fails with an error saying:

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

I've read that newer Django versions require an explicit django.setup() to be called, so I've tried to add it both to setUpClass(cls) and to setUpTestData(cls).

import django
from datamodel.models import Engagement, BusinessUnit
from django.contrib.auth.models import User
from django.test import TestCase, Client

class TestViewRPA(TestCase):
    @classmethod
    def setUpClass(cls):
        super(TestViewRPA, cls).setUpClass()
        django.setup()

    @classmethod
    def setUpTestData(cls):
        super(TestViewRPA, cls).setUpTestData()
        django.setup()
        User.objects.create_user('dummyuser')
        eng = Engagement.objects.create(name = 'Test Client', owner=User.objects.get(username='dummyuser'))
        businessunit = BusinessUnit.objects.create(name = 'Business Unit', engagement=eng)

    def test_get_industry_segment1(self):
        businessunit = BusinessUnit.objects.get(name = 'Business Unit')
        c = Client()
        response = c.get('/rpa/%d' % businessunit.id)
        self.assertContains(response, 'id":1,"businessunit_set":[{"id":1,', status_code=200)

Result from executing from CLI

...>env\Scripts\python.exe manage.py test app
Creating test database for alias 'default'...
System check identified no issues (0 silenced).

----------------------------------------------------------------------

OK
Destroying test database for alias 'default'...

Any ideas? Thanks in advance

You are getting this error because you are importing from before 之前从导入

You have already imported django so delete

from django.contrib.auth.models import User

and instead of

User.objects.create_user('dummyuser')

use django.contrib.auth.models like this

django.contrib.auth.models.User.objects.create_user('dummyuser')

or

if you want to keep everything simple just add django.setup() statement before importing anything from django.contrib.auth.models
