So you are saying that AOP (or cuts here for example,) can be used to create
DI where you don't already have it. Hmm.

#contrived
require 'collaborator'

class A
   def initialize
      @collab = Collaborator.new
   end
   # ...
end

# in TestCase
def setup
      @mock_collab = MockCollab.new     # or some DynamicMock library
end

cut NutherA < A
   def initialize
        @collab = @mock_collab  # ignore super for the example
   end
end

def test_add_mock_collab
    a = A.new
    assert_equals("expected", a.do_something_with_collab)
end

Is this what you were refering to with DI and Unit testing with AOP?

Can you expand on this a little? What are RealObjects (other than the
obvious) and PartialMocks? Aren't RealObjects just real objects that
are being mocked? How does the cut-style help?

Thanks
