python - Django 测试登录/注销

Question

我正在测试本教程中的一个 Django 应用程序:http://tutorial.djangogirls.org/en/django_admin/README.html

我已经根据示例创建了一个测试:

from django.test import TestCase, Client, LiveServerTestCase
from django.utils import timezone
from .models import Post
from django.contrib.auth.models import User

####Lines removed for brevity####

class AdminTest(LiveServerTestCase):
    fixtures = ['users.json']

    def setUp(self):
        self.client = Client()

    def test_login(self):
        # Get login page
        response = self.client.get('/admin/')

        # Check response code
        self.assertEquals(response.status_code, 200)

        # Check 'Log in' in response
        self.assertTrue('Log in' in response.content)

        # Log the user in
        self.client.login(username='XXX', password="XXX")

        # Check response code
        response = self.client.get('/admin/')
        self.assertEquals(response.status_code, 200)

        # Check 'Log out' in response
        self.assertTrue('Log out' in response.content)

    def test_logout(self):
        # Log in
        self.client.login(username='XXX', password="XXX")

        # Check response code
        response = self.client.get('/admin/')
        self.assertEquals(response.status_code, 200)

        # Check 'Log out' in response
        self.assertTrue('Log out' in response.content)

        # Log out
        self.client.logout()

        # Check response code
        response = self.client.get('/admin/')
        self.assertEquals(response.status_code, 200)

        # Check 'Log in' in response
        self.assertTrue('Log in' in response.content)

然而，当运行 python manage.py test 时，我得到了这个输出:

Creating test database for alias 'default'...
.FE
======================================================================
ERROR: test_logout (blog.tests.AdminTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File     "C:\Users\shenk\Documents\Programming\django_projects\djangogirls\blog\tests.py", line 80, in test_logout
self.assertTrue('Log out' in response.content)
TypeError: Type str doesn't support the buffer API

AssertionError: 302 != 200

----------------------------------------------------------------------

我得到了这个 302 响应代码，也就是重定向，我该如何调整这两个测试才能使它们通过并实际可用？

还有一个附带问题...我如何打印/检查 response.content 中的数据，因为打印到 STDOUT 似乎在测试中不起作用？

我在测试登录时发现了一个类似的问题，但问题是他们在创建没有密码的用户时，我的用户已经通过 createsuperuser 创建了。

Answer 1

看起来问题是我在注销后测试 200 代码，当时它将我重定向到另一个页面。要解决这个问题，我应该为 304 断言 Equals，然后再次为重定向页面上的 200 断言。这似乎已经解决了。
