Python Django注册测试脚本未运行

我试图在Django网站上为自定义注册表编写单元测试，但在运行

python manage.py测试时出错。我正在尝试运行以下测试：

def test_registration_valid_view(self):
    '''

    '''
    pass
    user_count = User.objects.count()
    form_data = {'username': 'test@example.com',
                 'first_name': 'Test',
                 'last_name': 'Person',
                 'password1': 'admin123',
                 'password2': 'admin123'}
    response = self.client.post("/sign-up/",
                                form_data)

    self.assertEqual(response.status_code, 200)
    self.assertEqual(User.objects.count(), user_count+1)

但我得到了以下错误：

我不知道这里有什么问题。有什么想法吗？
您的错误与此测试用例无关。Django在这方面失败了：

Group.objects.get（name='Consumers'）

您没有任何名为“消费者”的组。请记住，Django为单元测试设置了一个新的数据库，因此您必须在运行测试用例之前填充测试数据库。
谢谢，完全没有做到这一点！
