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)

我收到此错误：

您必须启用“sekizai.context_processors.sekizai”

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

这很令人困惑，因为我在我的 模板。

这篇文章为我指明了正确的方向。问题是 Django 提出了一个异常，但我从来没有看到它—— 只是这条不太有用的信息。

这篇 Stackoverflow 帖子解释了如何启用错误日志记录。一世 复制到 settings.py 的更改，将它们包装在 if 中 “测试”语句。

然后当我跑的时候

./manage.py 测试

我收到一条更有用的错误消息：我忘记设置 我的模板假设存在的表。轻松解决！

希望对其他人有所帮助。

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

8.1.1。解析视图名称

您的应用需要测试，但在您的实际站点中，它们不在 urls.py 中 因为它们附加到 CMS 页面。所以如果你想能够使用 reverse() 在您的测试中，或使用 url 模板的测试模板 标签，您需要将您的应用程序连接到 urls.py 的特殊测试版本 并告诉你的测试使用它。

因此您可以使用以下代码创建 myapp/tests/test_urls.py：

from django.contrib import admin from django.conf.urls import url, 模式，包括

urlpatterns = 模式('', 网址（r'^admin/'，包括（admin.site.urls））， 网址（r'^myapp/'，包括（'myapp.urls'））， url(r'', 包括('cms.urls')), )

然后在您的测试中，您可以使用 override_settings() 装饰器：

从 django.test.utils 导入 o​​verride_settings 从 cms.test_utils.testcases 导入 CMSTestCase

类 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

如果你想在整个测试类中测试 url conf，那么你 可以将装饰器应用到整个类：

从 django.test.utils 导入 o​​verride_settings 从 cms.test_utils.testcases 导入 CMSTestCase

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

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

Answer 2

为了解决 sekizai 错误，这就是我所做的：

from django.test import TestCase                                                
from sekizai.context import SekizaiContext                                      

from cms.api import add_plugin                                                  
from cms.models import Placeholder  
# Put class def here

def test_plugin(self):                                               
    placeholder = Placeholder.objects.create(slot='test')                   
    model_inst = add_plugin(placeholder,                                    
        cms_plugins.MyPlugin, 'en')                     
    context = SekizaiContext()                                              

    html = model_inst.render_plugin(context=context)                                                                                    
    self.assertTrue(len(html) > 0) 

这是一个确保在渲染插件期间使用 seikizai 上下文处理器的案例。
