组权限的Django TestCase？答案

我有一些视图的 TestCase，但我也在尝试为我的 post admin 组合并测试。他们拥有post.change_post 和post.delete_post 的权限，就像用户一样。

这是一个小代码sn-p，

from django.contrib.auth import get_user_model
from django.test import TestCase, Client
from django.urls import reverse
from fixtureless.factory import create

from .models import Post


class TestPostViews(TestCase):

    def setUp(self):
        super().setUp()
        self.user = get_user_model().objects.create(username='test_user')
        self.form = create(Post, {'title': 'test_title'})
        self.client = Client()


    def test_update_post(self):
        """
        Test UpdateView updates users post
        """
        self.client.force_login(user=self.user)
        response = self.client.put(reverse('post:update', kwargs={'pk': self.form.pk}),
                                   {'title': 'testing'})
        self.assertEqual(response.status_code, 200)

        # reloads a models value from the database
        self.form.refresh_from_db()
        self.assertEqual(self.form.title, 'test_title')

    def test_delete_confirm_page(self):
        """
        Test DeleteView takes user to confirmation page
        """
        self.client.force_login(user=self.user)
        response = self.client.get(reverse('post:delete', kwargs={'pk': self.form.pk}))
        self.assertContains(response, 'delete')

    def test_delete_post(self):
        """
        Test DeleteView deletes a post
        """
        self.client.force_login(user=self.user)
        response = self.client.post(reverse('post:delete', kwargs={'pk': self.form.pk}))
        self.assertRedirects(response, reverse('post:list'))
        self.assertFalse(Post.objects.filter(pk=self.form.pk).exists())

对此有什么建议吗？我应该为post admin 创建一个单独的TestCase，还是有办法在初始setUp() 方法中添加它？

【解决方案1】：

我想我离这个 sn-p 越来越近了...

class TestPostViews(TestCase):

    def setUp(self):
        super().setUp()
        self.user1 = get_user_model().objects.create(username='test_user1')
        self.user2 = get_user_model().objects.create(username='test_user2', 
                     password='test_pw')
        self.form = create(Post, {'user': self.user1, 'title': 'test_title'})
        self.client = Client()

        # Group setup
        group_name = "post admin"
        self.group = Group(name=group_name)
        self.group.save()

    def test_admin_can_delete(self):
        self.user2.groups.add(self.group)
        self.user2.save()
        self.client.login(username='test_user2', password='test_pw')

        response = self.client.post(reverse('posts:delete', kwargs={'pk': self.form.pk}))
        self.assertRedirects(response, reverse('posts:list'))

还是报错

Failure
Expected :'/accounts/login/?next=%2Fpost%2Fdelete%2F2143257160%2F'
Actual   :'/post/list/'
