为什么我的两个测试存在冲突,我有点失落。一次测试中的补丁似乎持续到另一次测试。如果我评论补丁测试,或者只是自己运行其他测试就没有问题。我的测试是:
class TestUrlRouting(TestCase):
@patch('myapp.views.Home')
def test_home_url_routes_to_home_view(self, mock_home_view):
url = reverse('home')
match = resolve(url)
assert match.func == mock_home_view.as_view()
class TestHomeView(TestCase):
def test_front_page_renders_home_template(self):
response = self.client.get('/')
self.assertTemplateUsed(response, 'home.html')
Home
视图为TemplateView
。我最终得到的错误是:
Traceback (most recent call last):

因为我没有对补丁装饰器做任何特别的事情,我的猜测是它与Django如何设置有关。特别是,我发现修补myapp.urls.Home
不起作用。相反,我需要修补myapp.views.Home
,尽管被测线在urls.py
为url(r'^$', Home.as_view(), name='home'),
。有什么想法为什么这个补丁持续存在以及我如何解决它?非常感谢!
更新
即使在模仿myapp.views.Home.as_view
而不仅仅是myapp.views.Home
时问题仍然存在(再一次,注意views
是正确模拟的选项,而不是urls
由于某种原因)。
答案 0 :(得分:0)
.as_view()
的调用仅在导入时进行一次(Django第一次需要访问&#34; urls.py&#34;),这就是为什么&#39}&# 34;持续&#34;
IMO你的第一个测试用例只是测试Django框架,而不是你自己代码中的任何东西,除了主视图的网址名称为&#34; home&#34;。挑剔是不值得的。您可以轻松地覆盖reverse('home')
在另一个不需要模拟Django全局变量的测试用例中将您带到正确的视图。
