上下文：在我目前的项目中，我正在尝试使用plone.app.testing设置测试环境。 该代码可在github上找到：https://github.com/collective/collective.rcse
我正在尝试在设置中添加一些成员，但它引发了以下异常：

调用此跟踪显示膜以添加成员但在尝试查找IUserAdder组件时，组件注册表会在以下代码中引发异常：
def _wrap(comp, registry):
"""Return an aq wrapped component with the site as the parent but
only if the comp has an aq wrapper to begin with.
"""
# If component is stored as a ComponentPathWrapper, we traverse to
# the component using the stored path:
if isinstance(comp, ComponentPathWrapper):
comp = getSite().unrestrictedTraverse(comp.path)
if IAcquirer.providedBy(comp):
return _rewrap(comp)
else:
return comp
# BBB: The primary reason for doing this sort of wrapping of
# returned utilities is to support CMF tool-like functionality where
# a tool expects its aq_parent to be the portal object. New code
# (ie new utilities) should not rely on this predictability to
# get the portal object and should search out an alternate means
# (possibly retrieve the ISiteRoot utility). Although in most
# cases getting at the portal object shouldn't be the required pattern
# but instead looking up required functionality via other (possibly
# local) components.
if registry.__bases__ and IAcquirer.providedBy(comp):
current_site = getSite()
registry_site = Acquisition.aq_base(registry.__parent__)
if not ISite.providedBy(registry_site):
registry_site = registry_site.__parent__
...
在测试期间，registry_site没有父级。以下是我尝试使用PDB的内容：
(Pdb) registry_site
<BaseGlobalComponents test-stack-3>
(Pdb) ISite.providedBy(registry_site)
False
(Pdb) registry
<zope.component.globalregistry.GlobalAdapterRegistry object at 0x105499990>
(Pdb) getSite()
<PloneSite at /plone>
(Pdb) Acquisition.aq_base(registry.__parent__)
<BaseGlobalComponents test-stack-3>
(Pdb) registry.__bases__
(<zope.component.globalregistry.GlobalAdapterRegistry object at 0x1049238d0>,)
(Pdb) registry
<zope.component.globalregistry.GlobalAdapterRegistry object at 0x105499990>
因为它只在测试期间发生，这意味着我必须在测试设置中添加一些内容。

这应该是我们如何设置的：
def setUpZope(self, app, configurationContext):
import collective.indexing
import Products.membrane
self.loadZCML(package=collective.indexing)
self.loadZCML(package=Products.membrane)
z2.installProduct(app, 'collective.indexing')
z2.installProduct(app, 'Products.membrane')
# + your dexterity.membrane product setup
def setUpPloneSite(self, portal):
from zope.publisher.browser import TestRequest
from zope.globalrequest import setRequest
request = TestRequest()
setRequest(request)
# + your dexterity.membrane product policy
# + create (and reindex) content (with dexterity.membrane)
import transaction
transaction commit()
然而，当其他所有方法都失败了，并且您正在尝试进行功能测试，而您在包中使用<includeDependencies /> - 指令时，可以在{{1}中为您的装置重新启用z3c.autoinclude与...：
setUpZope答案 1 :(得分：2)
我们找到了解决方案。
我们使用的自定义用户加法器是SimpleItem而不是持久性的。 five.localsitemanager试图获得一些实际上无法获得的东西。将其更改为对象有效。

不知道为什么它在测试之外工作。
