ComponentLookupError when testing with plone.app.testing on Plone 3.x

I ran into this error running the test for my product, written using plone.app.testing on Plone 3.3.5:

ComponentLookupError: (<InterfaceClass plone.app.viewletmanager.interfaces.IViewletSettingsStorage>, '')

but the product works correctly outside of the test.

Solution

  • It turns out I specified the wrong version for plone.testing.

    These are the correct versions to use with Plone 3.x ATM (december 2011):

    plone.app.testing = 3.0a1
plone.testing = 3.0a2

    The error above was caused by plone.testing being pinned to 3.0a1.
