如何测试主页的加载？

请帮助修复测试。 tests.py：如何测试主页的加载？

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)), 
)

为控制台测试的结果显示下列错误消息：

抛出的错误非常清楚：'IndexError'。您想在'models.py'的某个位置检索空的查询集的第一个元素。这就是我没有你的模型文件的实际代码所能说的。 – linkyndy

每个试验从空白开始数据库。如果你没有在你自己的测试中创建任何数据，例如在setUp方法或者通过灯具，那么你正在测试的视图将找不到任何数据。在这种情况下，您的get_main_page方法预计在Page模型中至少有一个条目，并且您没有任何条目。

当然，这实际上暴露了您的代码本身的错误：当没有数据时它崩溃。如果这是一个用例，你需要处理，那么你应该检查这种情况并显示一个合适的错误页面。
