I think you need to clarify what you mean by 'spec an attachment_fu model'.
Do you want the validates_as_attachment to succeed with your test data, for instance? If so, simply stub the call: Picture.should_receive(:validates_as_attachment) so that you can be confident the model does the right thing (ensuring it is validated in real life) but the real validation code is never called and so never added to the validation chain, so your test models will save without hassle. I think that's the gist of your problem - you can't get test model instances to validate and so cannot write meaningful tests? Alternatively you may have to include your failing specs so we can understand your situation more clearly.
