Question

请帮助修复测试。 tests.py：

from django.test import TestCase
from django.test.client import Client
import os
from django.conf import settings


class HomePageTest(TestCase):

    def test_homepage_available(self):
        c = Client()
        response = c.get('/')
        self.assertEquals(response.status_code, 200)

urls.py:

from django.conf.urls import patterns, include, url
from django.conf import settings
#from django.conf.urls.static import static

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^$', 'mutants.views.inner_page', name='home'),
    url(r'^admin/', include(admin.site.urls)),
)

由于在控制台中进行测试，显示以下错误消息：

c:\Python33\django_projects\mutants>python manage.py test

每个测试都从空白数据库开始。如果您不在自己的测试中创建任何数据，例如在setUp方法中或通过fixture，那么您正在测试的视图将无法找到任何数据。在这种情况下，您的get_main_page方法预计Page模式中至少有一个条目，并且您没有任何条目。

当然，这实际上暴露了代码本身的一个错误：它在没有数据时崩溃。如果这是您需要处理的用例，那么您应该检查该情况并显示正确的错误页面。
