python - Django 单元测试 Sekizai 和 django cms

Question

如何在 Django 中编写测试？我阅读了文档:https://docs.djangoproject.com/en/dev/topics/testing/overview/

但是我们使用 django-cms 和 sekizai 所以当我做一个简单的测试时:

from django.test import TestCase
from django.test.client import Client

class AccessTest(TestCase):
    def setUp(self):
        # Every test needs a client.
        self.client = Client()

    def test_details(self):
        # Issue a GET request.
        response = self.client.get('/')

        # Check that the response is 200 OK.
        self.assertEqual(response.status_code, 200)

我收到这个错误:

You must enable the 'sekizai.context_processors.sekizai'

关于这部分，我的 TEMPLATE_CONTEXT_PROCESSORS 中有 sekizai.context_processors.sekizai。

This was confusing because I was using sekizai correctly in my template.

This post pointed me in the right direction here. The problem was Django was raising an exception but I was never getting to see it – just this much less helpful message.

This Stackoverflow post explained how to enable logging of errors. I copied in the changes to settings.py, wrapping them inside the if 'test' statement.

Then when I ran

./manage.py test

I got a much more useful error message: I had forgotten to set up a table that my template was assuming would exist. Easily fixed!

Hope that helps someone else.

我需要添加一些固定装置才能让它工作。

编辑:好的，经过大量研究后，我发现尽管有上述博客，但我遇到了不同的问题。

感谢这个答案和这个文档，我知道我必须这样做:

from django.test import TestCase
from django.test.client import Client
from cms.test_utils.testcases import CMSTestCase
from django.test.utils import override_settings
from cms.models import Page
from django.contrib import admin
from django.conf.urls import url, patterns, include
from django.conf import settings

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^search_engine/', include('search_engine.urls')),
    url(r'', include('cms.urls')),
)


class AccessTest(CMSTestCase):

    def setUp(self):
        # Every test needs a client.
        p = Page.objects.create(site_id=settings.SITE_ID, template='home_page.html')
        p.publish()
        self.client = Client()

    @override_settings(ROOT_URLCONF='search_engine.tests')
    def test_details(self):
        # Issue a GET request.
        response = self.client.get('/')

        # Check that the response is 200 OK.
        self.assertEqual(response.status_code, 200)

How to unit test Django-CMS extensions?和 http://docs.django-cms.org/en/latest/extending_cms/testing.html <= 不知何故，这只能在“最新”中阅读

8.1.1. Resolving View Names

Your apps need testing, but in your live site they aren’t in urls.py as they are attached to a CMS page. So if you want to be able to use reverse() in your tests, or test templates that use the url template tag, you need to hook up your app to a special test version of urls.py and tell your tests to use that.

So you could create myapp/tests/test_urls.py with the following code:

from django.contrib import admin from django.conf.urls import url, patterns, include

urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), url(r'^myapp/', include('myapp.urls')), url(r'', include('cms.urls')), )

And then in your tests you can plug this in with the override_settings() decorator:

from django.test.utils import override_settings from cms.test_utils.testcases import CMSTestCase

class MyappTests(CMSTestCase):

@override_settings(ROOT_URLCONF='myapp.tests.test_urls')
def test_myapp_page(self):
    test_url = reverse('myapp_view_name')
    # rest of test as normal

If you want to the test url conf throughout your test class, then you can use apply the decorator to the whole class:

from django.test.utils import override_settings from cms.test_utils.testcases import CMSTestCase

@override_settings(ROOT_URLCONF='myapp.tests.test_urls') class MyappTests(CMSTestCase):

def test_myapp_page(self):
    test_url = reverse('myapp_view_name')
    # rest of test as normal
