如何从视图类测试 Django 重定向

Question

我正在学习 Django atm，但我一直坚持创建一个简单的测试用例。

如何测试以下视图？如果用户已经登录，它会将他重定向到列表视图。

from django.shortcuts import render
from django.contrib.auth import authenticate, login, logout
from django.contrib.auth.forms import AuthenticationForm
from django.views.generic import TemplateView
from django.core.urlresolvers import reverse
from django.shortcuts import redirect

class LoginView(TemplateView):
    """
    Base class for client area login.
    """
    def get(self, request, *args, **kwargs):
        """
        Display login form, only if user is not yet authenticated.
        Otherwise redirect to tickets index.
        :param request:
        :param args:
        :param kwargs:
        :return:
        """
        if request.user.is_authenticated():
            return redirect(reverse('tickets:index'))

        form = AuthenticationForm()

        return render(request, 'login.html', {'form': form})

到目前为止，我创建的测试如下所示：

from django.test import TestCase, RequestFactory
from django.core.urlresolvers import reverse
from django.contrib.auth.models import User, AnonymousUser
from app.account.views import LoginView


class TestLoginForm(TestCase):

    def setUp(self):
        """
        Set up environment
        :return:
        """
        self.user = User.objects.create_user(username="test", password="test123", email="test@gmail.com")
        self.factory = RequestFactory()

    def tearDown(self):
        """
        Clean created user object
        :return:
        """
        self.user.delete()
        self.factory = None

    def test_login_form_redirect(self):
        """
        Test login redirect
        :return:
        """


        request = self.factory.get(reverse('account:login'))
        request.user = AnonymousUser()

        view = LoginView()
        response = view.get(request=request)
        self.assertEqual(response.status_code, 200)

        request.user = self.user
        response = view.get(request=request)
        self.assertRedirects(response, expected_url=reverse('tickets:index'), status_code=302, target_status_code=200)

第一个断言通过，但如果用户已经登录，则应该重定向的第二个断言会引发此错误

AttributeError: 'HttpResponseRedirect' object has no attribute 'client'

我做错了什么？

好的，我已经成功制作了测试用例，代码如下

def test_login_form_redirect(self):
    """
    Test login redirect
    :return:
    """

    self.client.logout()

    response = self.client.get(reverse('account:login'))
    self.assertEqual(response.status_code, 200)

    self.assertTrue(self.client.login(username='test', password='test123'))
    response = self.client.get(reverse('account:login'))
    self.assertRedirects(response, expected_url=reverse('tickets:index'), status_code=302, target_status_code=200)
