[Product-Developers] ImportErrors while testing using testrunner

[Kees Hink]

I'm trying to get zc.recipe.testrunner to test a specific package, but i get
ImportError for "deferredimport" and "app.testing" (http://pastie.org/819976).

Clearly, some dependencies are missing, but should i add these dependencies of
zc.recipe.testrunner manually? Is something wrong with my buildout (Plone 4.0a4
buildout)? Or should i add extra info in the [test] section?

Excerpts from my buildout-dvl.cfg:
[test]
recipe = zc.recipe.testrunner
eggs =
    contentratings

[buildout]
extensions = mr.developer
...
auto-checkout =
    plone.contentratings
    contentratings

https://svn.plone.org/svn/collective/collective.examples.userdata/trunk/
plone.contentratings = svn
https://svn.plone.org/svn/collective/plone.contentratings/trunk/
contentratings = svn https://svn.plone.org/svn/collective/contentratings/trunk/

(contentratings is a dependency of plone.contentratings)
