如何反轉（'opensearch'）在shell中工作，但在測試中失敗？

Question

我正試圖將django-lean安裝到我的應用程序中。

開放式搜索用於我的應用程序應用程序。

我可以在Python shell中反轉（'opensearch'）。然而，在測試中，反向（「OpenSearch的」）* NoReverseMatch：反轉「的OpenSearch」與參數「（）」和關鍵字參數

In [47]: reverse('opensearch') 
Out[47]: '/opensearch.xml' 
In [48]: response = client.get('/opensearch.xml') 
In [49]: response.status_code 
Out[49]: 200 

這是一個試圖從測試做同樣的，通過停止pdb.set_trace（）

No fixtures found. 
> /usr/local/lib/python2.7/site-packages/django_lean-0.15-py2.7.egg/django_lean/experiments/tests/test_tags.py(72)doTestIntegration() 
-> response = client.get("confirm_human") # this is where the Client can't find the url 
(Pdb) reverse('opensearch') 
*** NoReverseMatch: Reverse for 'opensearch' with arguments '()' and keyword arguments '{}' not found. 

下面是從urls.py代碼：

url(r'^opensearch\.xml$', app.meta.opensearch, name='opensearch'), 

最後，這裏是爲失敗的測試traceroute的：

看起來像是可能是Bug 11077。如果是這樣，問題是TestCase覆蓋urlconf，正如在this comment中指出的那樣：「問題在於事實上，對於django.contrib.auth和django-registration的測試都將它們的TestCase.urls設置設置爲覆蓋默認的URLConf 「。
