Django单元测试响应上下文为无

问题描述

为什么在以下测试中没有response.context？我已经检查了response.content，它是''。如果我删除assertIsNotNone行，我得到一个TypeError：'NoneType'对象不可订阅

Why is response.context None in the following tests? I've checked response.content and it is ''. if I remove the assertIsNotNone line I get a TypeError: 'NoneType' object is not subscribable

def test_log_view_with_no_entries(self):
    """
    If no logs are available, an appropriate message should be displayed.
    """
    response = self.client.get(reverse('swpgr:logs'))
    self.assertIsNotNone(response.context)
    self.assertEqual(response.status_code, 200)
    self.assertContains(response, "No logs are available.")
    self.assertQuerysetEqual(response.context['log_list'], [])

def test_log_view_with_one_entry(self):
    """
    Logs should be displayed it table.
    """
    time = timezone.now()
    t = LogEntry.objects.create(event_date=time, command_type="Test", command_source="Test Case",
        username="user")
    response = self.client.get(reverse('swpgr:logs'))
    self.assertIsNotNone(response.context)
    self.assertQuerysetEqual(
        response.context['log_list'],
        ['<LogEntry: 1 Test user: user>']
    )`

推荐答案

我遇到这个问题，并修复它在setUp函数中执行以下操作：

I was having this issue and to fix it did the following in the setUp function:

from django.test.utils import setup_test_environment
setup_test_environment()
