python - self.assertContains 失败；在响应中找不到 *word*

问题描述

我很难完全渲染TopicsPage. 假设渲染sub_heading.html哪个扩展listing.html（两个模板都位于同一个模板文件夹中）。测试通过了self.assertTemplateUsed()断言。

然而，在以下情况下会引发 AssertionError：

self.assertContains(response, "Looking for more?")

AssertionError: False is not true : Couldn't find 'Looking for more?' in response

sub_heading.html当模板已经被使用时，如何获取要渲染的内容以通过测试？我故意将 GET 方法的实现pass只是为了展示我如何对视图进行子类化。

test_views.py

class TestTopicsPage__002(TestCase):
    '''Verify that a topic and associated information is displayed
    on the main page once the topic is created'''

    @classmethod
    def setUpTestData(cls):
        user = User.objects.create_user("TestUser")
        python_tag = Tag.objects.create(name="Python")
        js_tag = Tag.objects.create(name="JavaScript")
        content = {
            'heading': "Test Title",
            'text': "Mock text content",
            'posted': datetime.datetime.now()
        }

        cls.topic = Topic(**content)
        cls.topic.author = user
        cls.topic.save()
        cls.topic.tags.add(python_tag, js_tag)

    def test_topics_main_page_rendered_topics(self):
        response = self.client.get(
            reverse("listing")
        )
        self.assertEqual(response.status_code, 200)
        self.assertTemplateUsed(response, "topics/sub_listing.html")
        self.assertContains(response, "Looking for more?")

        context = self.get_context_data()
        form = context['login_form'](data=request.POST)

            resolver = resolve(request.path)
