Question

我在这里为一些create，update视图编写一些api测试用例，但是我尝试这样做。但这给了我错误。我可能做错了什么？有什么解决方案吗？

self.assertEqual(response.status_code,status.HTTP_200_OK)
AssertionError: 403 != 200

Answer 1

由于IsAdminUser权限，所有视图仅允许超级用户使用，因此您将获得403代码。

您需要通过以管理员用户身份登录进行测试。您可以使用login的{{1}}方法来做到这一点。

对于“创建”测试方法，您需要在输入中提供有效的产品，以测试要创建产品的视图。

这是您的Client()和CreateProductTest的示例测试用例：

ListProductTest

Answer 2

要遵循的步骤

使用setUp方法创建用户
在test_<method>中认证用户
发送请求以包含数据的网址

CREATE_PRODUCT_URL = reverse('product:create-product')

class CreateProductTest(APITestCase):
    def setUp(self):
        self.client = Client()
        self.user = User(username="testuser", email="testemail@test.com")
        self.user.is_staff = True
        self.user.set_password('secret')
        self.user.save()

    def test_details(self):
        self.assertTrue(self.client.login(username="testuser", password="secret"))
        post_data = {} # your data here in dict
        response = self.client.post(CREATE_PRODUCT_URL, post_data, format='json')
        print(response.status_code)
        self.assertEqual(response.status_code,status.HTTP_201_CREATED)

如何在Django Rest框架中为基于通用类的视图编写API测试用例？
