Plone单元测试不加载依赖包配置文件

Question

我为Plone 4.2开发了一个附加组件,我正在编写测试.当我执行

# bin/test -s my.stream

我收到以下错误:KeyError:u'profile-my.common:default' 为什么我收到错误？

这里有一些可能有用的信息.

my.stream依赖于my.common.两者都是/ blah/user/blah/buildout/src中的附加组件.它们由mr.developer管理.

我的扩建包括所有开发蛋:

[buildout]
...
eggs =
  my.common
  my.stream
...

[test]
recipe = zc.recipe.testrunner
defaults = ['--auto-color', '--auto-progress']
eggs =
  ${instance:eggs}

我的testing.py:

from plone.app.testing import PloneSandboxLayer
from plone.app.testing import applyProfile
from plone.app.testing import PLONE_FIXTURE
from plone.app.testing import IntegrationTesting

from zope.configuration import xmlconfig

class MyStreamContent(PloneSandboxLayer):

    defaultBases = (PLONE_FIXTURE,)

    def setUpZope(self, app, configurationContext):
        # Load ZCML
        import my.stream
        xmlconfig.file('configure.zcml',
                       my.stream,
                       context=configurationContext)

    def setUpPloneSite(self, portal):
        applyProfile(portal, 'my.stream:default')

MY__FIXTURE = MyStreamContent()
MY__INTEGRATION_TESTING = IntegrationTesting(
        bases=(MY__FIXTURE,),
        name='MyStreamContent:Integration')

我错过了什么？

提前致谢.

您需要进行单元测试以加载依赖包ZCML.它们不会自动加载(与Plone启动时不同),因为加载所有不需要的软件包会大大减慢运行测试的速度.

有几种方法,但这很可能有效:

def setUpZope(self, app, configurationContext):
    # Load ZCML
    import my.common
    self.loadZCML(package=my.common)

    # my.setup goes here

此外,包应该是分层的,这样如果my.common提供测试,那么my.stream测试层将依赖于my.common层并记住调用它们的super()方法,因此类层次结构将负责初始化依赖包.
