[Product-Developers] Setting up enough zcml in testing

I am trying to get the roadrunner testrunner working in my buildout.
See http://pypi.python.org/pypi/roadrunner

roadrunner speeds up testing by preloading a standard Zope and Plone
test environment compatible with PloneTestCase.

For this to work, the test setup in your product/package needs to be
pretty good.  Following these guidelines should be enough:


I added it in this buildout:

bin/roadrunner -s Products.eXtremeManagement now works.

bin/roadrunner -s xm.tracker gives errors, because not enough (meta)
zcml is loaded; on the other hand, 'bin/instance test -s xm.tracker'
works fine.  The xm.tracker tests use the layer and setup defined in
Products.eXtremeManagement, so I would expect that roadrunner then
also works for both.  Test errors are for instance this one:

    ConfigurationError: ('Unknown directive',
      u'http://namespaces.zope.org/zope', u'permission')

I have begun fixing this and similar errors with extra lines in a
Products.PloneTestCase.layer.onsetup function.  I currently already
have this:

    fiveconfigure.debug_mode = True
    import zope.security
    import zope.component
    import Products.Five
    import kss.core
    import Products.GenericSetup
    import plone.app.portlets
    import Products.CMFCore
    import Products.CMFDynamicViewFTI
    import Products.DCWorkflow
    zcml.load_config('meta.zcml', zope.security)
    zcml.load_config('meta.zcml', zope.component)
    zcml.load_config('meta.zcml', Products.Five)
    zcml.load_config('meta.zcml', Products.Five.viewlet)
    zcml.load_config('meta.zcml', kss.core.pluginregistry)
    zcml.load_config('meta.zcml', Products.GenericSetup)
    zcml.load_config('meta.zcml', plone.app.portlets)
    zcml.load_config('meta.zcml', Products.CMFCore)
    zcml.load_config('permissions.zcml', Products.Five)
    zcml.load_config('configure.zcml', Products.CMFDynamicViewFTI)
    zcml.load_config('tool.zcml', Products.DCWorkflow)

All those lines help.  But they are not enough, as I now get this error:

  zope.component.interfaces.ComponentLookupError: (<InterfaceClass
    Products.MailHost.interfaces.IMailHost>, u'')

That one is probably fixable as well.  But there has *got* to be a
better way, with less lines, that actually works and lets me have the
time gains promised by roadrunner.  So... what is it? :-)
