跑单个用例通过，但是跑整个用例套失败

Question

views的测试，每个用例单独跑能通过，跑测试套就出现bad request，请问老师是什么原因？

报错如下：

def test_delete_view(self):
    init_total = News.objects.count()
    # response = self.other_client.post(reverse('news:delete_news', kwargs={'pk': self.second_news.pk}))
    response = self.client.post(reverse('news:delete_news', kwargs={'pk': self.second_news.pk}))
    assert response.status_code == 302
    self.assertEqual(News.objects.count(), init_total - 1)
    
    问题：
    self.client是用first_user登录的，用这个client删除第一条动态肯定是不行的，用self.other_client就成功了

您好，报Traceback 错误的话，不是测试结果失败，而是测试用例本身写的有问题报错了，能否截图一下你测试用例的完整代码呢？当然还有一种可能，你测试用例写得和视频里一样，但是被测试的功能写错了

  添加了截图，麻烦老师帮忙看下。
  情况是，我依次执行每条用例都跑的通，运行整个测试套时全错

• Jack 回复 提问者 ian116 #2

  代码看了几遍没发现问题，单独运行test_get_thread函数没有报错吗

• 提问者 ian116 回复 Jack #3

  单独运行任意函数都没有报错。算了 不纠结了 往下学习了
