我如何单元测试django urls？ [英] How do I unit test django urls?

问题描述

我在我的应用中取得了100％的测试覆盖率无处不在，除了我的 urls.py 。你有没有建议我如何为我的URL编写有意义的单元测试？

I have achieved 100% test coverage in my application everywhere except my urls.py. Do you have any recommendations for how I could write meaningful unit tests for my URLs?

FWIW这个问题是因为我正在试验测试在编写代码以解决问题之前，需要进行开发并想要失败的测试。

FWIW This question has arisen as I am experimenting with Test-Driven Development and want failing tests before I write code to fix them.

推荐答案

一种方法是 reverse URL名称和验证

One way would be to reverse URL names and validate

示例

urlpatterns = [
    url(r'^archive/(\d{4})/$', archive, name="archive"),
    url(r'^archive-summary/(\d{4})/$', archive, name="archive-summary"),
]

现在，在测试

from django.urls import reverse

url = reverse('archive', args=[1988])
assertEqual(url, '/archive/1988/')

url = reverse('archive-summary', args=[1988])
assertEqual(url, '/archive-summary/1988/')

您可能反正测试的意见。

You are probably testing the views anyways.

现在，为了测试URL连接到正确的视图，您可以使用 resolve

Now, to test that the URL connect to the right view, you could use resolve

from django.urls import resolve

resolver = resolve('/summary/')
assertEqual(resolver.view_name, 'summary')

现在分解器（ ResolverMatch 类实例） ，您有以下选项

Now in the variable resolver (ResolverMatch class instance), you have the following options

 'app_name',
 'app_names',
 'args',
 'func',
 'kwargs',
 'namespace',
 'namespaces',
 'url_name',
 'view_name'
