如何为受身份验证保护的restapi编写Django单元测试？

Question

我看了两个答案，也许已经有了我的答案，但坦率地说，我就是不明白。这些SO post是：Django Rest Framework API Authentication Test和{a2}。在

这两个问题使用不同的方法。在

我尝试使用的方法是这样的。我创建了这个类：

from rest_framework.test import APIClient
from django.test import testcases
from django.contrib.auth.models import User

class RemoteAuthenticatedTest(testcases.TestCase):
    client_class = APIClient

    def setUp(self):
        self.username = 'mister_neutron'
        self.user = User.objects.create_user(username='mister_neutron',
                                          email='mister_neutron@example.com',
                                             password='F4kePaSs0d')
        super(RemoteAuthenticatedTest, self).setUp()

我的单元测试是这样的：

^{pr2}$

我把这个放在我的设置.py文件：

#Authentications
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    ),
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',
    ),
}

当我运行测试时，我得到以下结果：

Failure
Traceback (most recent call last):
  File "/myproject/info/tests.py", line 686, in create_info_record
    self.assertEqual(response.status_code, status.HTTP_201_CREATED)
AssertionError: 401 != 201

我做错什么了？在

更新：在遵循@henriquesalvaro sage的建议后，我将代码更新为：

from rest_framework.test import APIClient,APITestCase
from django.contrib.auth.models import User
from rest_framework.authtoken.models import Token

class RemoteAuthenticatedTest(APITestCase):
    client_class = APIClient

    def setUp(self):
        self.username = 'mister_neutron'
        self.user = User.objects.create_user(username='mister_neutron',
                                             email='mister_neutron@example.com',
                                             password='F4kePaSs0d')
        Token.objects.create(user=self.user)
        super(RemoteAuthenticatedTest, self).setUp() 

我更新了我的测试用例：

class InfoViewTestCase(RemoteAuthenticatedTest):
    def create_info_record(self):
        from random import randint
        blade = 'test-blade-host-name-%s' % (randint(0, 100))
        breachs = randint(0,100)
        dimm = 'test dimm slot %s' % (randint(0,100))
        url = reverse('info:info_creat')
        data = {
            'blade_hostname': blade,
            'breach_count': breachs,
            'dimm_slot': dimm,
        }
        self.client.credentials(HTTP_AUTHORIZATION='Token ' + self.user.auth_token.key)
        response = self.client.post(url, 
                                    data, 
                                    format='json', 
                                    REMOTE_USER=self.username)
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)
        self.assertEqual(Info.objects.count(), 1)
        self.assertEqual(Info.objects.get().blade_hostname, blade)

现在我的单元测试通过了。在

在遵循@henriquesalvaro（见注释）sage建议后，我将代码更新为：

from rest_framework.test import APIClient,APITestCase
from django.contrib.auth.models import User
from rest_framework.authtoken.models import Token

class RemoteAuthenticatedTest(APITestCase):
    client_class = APIClient

    def setUp(self):
        self.username = 'mister_neutron'
        self.user = User.objects.create_user(username='mister_neutron',
                                             email='mister_neutron@example.com',
                                             password='F4kePaSs0d')
        Token.objects.create(user=self.user)
        super(RemoteAuthenticatedTest, self).setUp() 

我更新了我的测试用例：

现在我的单元测试通过了。在
