Python 尝试测试在dajngo中使用request.session[key]的视图

我尝试使用

request.session['key']

值在views.py上进行测试，其中文件只有一行

def updateaccout(request):
    username = request.session['username']
    profile = Account.objects.get(username=username)
    return render(request, "user/profile .html",profile )

在test.py文件中，我尝试了两个集合

def test_updateaccout(self):
    self.client.login(username='john', password='johnpassword')
    session = self.client.session
    session['username'] = 'john'
    session.save()
    c = Client()
    data = {'username' : 'john'}
    response = c.post('/account', data,follow=True)
    self.assertEqual(response.status_code,200)

ERROR: test_updateaccout (user.tests.UsersTestCase)

    return self._session[key]
KeyError: 'username'

我尝试设置的另一个是添加

self.\u session['username']='john'

，但它说

AttributeError:'UsersTestCase'对象没有属性'\u session'

我如何测试这个？或者我应该分离测试URL和表单，但仍然没有测试视图

谢谢

您不能在客户端设置会话变量。会话变量存储在服务器端，客户端只存储cookie。你是说self.\u Session['username'，对吗？我不知道该怎么办。所以我决定试试。不，

self.\u session

肯定不起作用，因为

TestCase

没有session属性，self.\u session[key]中的

self

是会话后端。
