Comment 3 for bug 580083

Looking at bin/test as generated by buildout I see[
        '--test-path', '/home/mg/src/zope.testrunner/src',
        '--test-path', '/home/mg/.buildout/eggs/zope.testing-3.9.5-py2.6.egg',

which means it's trying to run zope.testing's test suite too, which fails.

My fault: I added zope.testing to buildout.cfg:

  recipe = zc.recipe.testrunner
  eggs = zope.testrunner

because zope.testrunner itself doesn't depend on zope.testing and thus bin/test used to fail with an import error.

What's the right buildout incantation of enabling extra test dependencies without running their tests?
