此例外让我感到难过。在使用rest_framework APITestCases之前，我只是编写以下单元测试作为示例来学习Django单元测试系统。
我已重置我的环境，并在Django调试交互式环境中使用相同的代码进行了测试，并尝试通过多种方式向用户添加。单元测试仍然失败，调试外壳仍然有效...
我编写了以下测试（出于谨慎，我省略了assert语句...）
class modelsTests(TestCase):
def testUserModel(self):
# we should begin with no users...
self.assertEquals(
User.objects.count(),
0
)
# create some demo users, 2 exactly...
User.objects.create(username="test user", email="[email protected]")
# add the first user to a group, not the second
Group.objects.create(name="Test")
user = User.objects.first()
user.groups.add(Group.objects.get(name="Test"))
# create the second user without any groups
User.objects.create(username="another user", email="[email protected]")
然后我运行测试（在代码段后包含几个assert语句），py manage.py test testdrivendevelopment.tests这将返回以下错误代码和堆栈跟踪，
Creating test database for alias 'default'...
System check identified no issues (0 silenced).

此异常似乎表明我将组错误地传递给用户以添加它！但是，我通过快速搜索在this question中看到了。我也可以做相反的事情，并将用户从组对象添加到组中。尝试过并获得相同的堆栈跟踪后，我转向了Django调试控制台。复制和粘贴本例中预期的相同代码和导入的内容。
总而言之，如果这似乎是如此失败，那么如何测试将用户添加到组中？ 为什么的奖励积分。
创建用户方法如下
User.objects.create_user(username="test user", email="[email protected]")
