无法在 DJANGO 中完成基于 Unittest 类的视图

Question

如何使用 django 完成此视图单元测试？ 我开始使用 unittest，但由于某种原因，我无法成功完成第一个基于类的视图测试。

models.py

class BookListView(ListView):
    model = Book
    context_object_name = 'books'
    template_name = 'snippets/list.html'

urls.py

from django.contrib import admin
from django.urls import path, include
from .views import (BookListView)
from . import views


app_name = 'snippets'
urlpatterns = [
    path('', views.index, name='book_list'),

views.py

from django.test import TestCase, Client
from django.urls import reverse
from snippets.models import Book
import json



class TestViews(TestCase):

    def setUp(self):
        self.client = Client()

    def test_book_list_GET(self):
        response = self.client.get(reverse('snippets:book_list'))
        self.assertEqual(response.status_code, 200)
        self.assertTemplateUsed(response, 'snippets/list.html')

下面是终端崩溃的反馈

self.assertEqual(response.status_code, 200)
AssertionError: 404 != 200

如前所述：

class TestViews(TestCase):

    def setUp(self):
        self.client = Client()

    def test_book_list_GET(self):
        response = self.client.get('snippets:book_list')
        self.assertEqual(response.status_code, 200)
        self.assertTemplateUsed(response, 'snippets/list.html')

您需要在此处传递 url，django.urls.utils.reverse 将为您提供视图的相对 url
