@thet Merging this broke all of our jenkins tests like this:

Exception: You try to run plone.testing tests together with ZopeTestCase tests. This will result in random failures. Convert the ZopeTestCase Tests or do not run them together

You can easily reproduce it locally like this: ./bin/test -s Products.DCWorkflow -s plone.namedfile -D

I don't really know what the warning is good for. We have not had random errors since we fixed all test-isolation-issues.

I think we can remove this and the following lines all together?
Looking at it, I can't make sense of importing something and then throwing an error if the import was successful.
@datakurre @pbauer

[pbauer]

I agree. It seems that running ZopeTestCase together with ours had side-effects that needed to be warned about. See 3268cda
I should hope that these issues are gone.

[thet]

Ah, yes, that makes sense.
I remeber also, that was done at the Alpine City Sprint.
