When you use the installProduct command of ZopeTestCase on a product that has a CMFSetup profile you may get the following error: File "/home/zopes/27test/Products/CMFSetup/registry.py", line 567, in registerProfile raise KeyError, 'Duplicate profile ID: %s' % profile_id KeyError: 'Duplicate profile ID: <profile id>' This typically happens on the profile "CMFDefault:default". This also *only* happens if you try to run all tests in Products. The reason seem to be that all or some of the products gets installed by Zope. When you then try to install them again with installProduct, you get the error. My suggested solution is to "merge" ZopeTestCases list of installed products with Zopes list of installed products, as these for the moment are not the same, as far as I can see. This error happens both with Zope2.7 and 2.8.
