I think I must mostly use constructor injection, as I don't really  
seem to have a pattern for this, but if I did I guess it would be  
something like this:

     extend StubbingHelpers

     describe "blah"
       before(:each) do
         @authenticator = mock_new_authenticator( :foo => bar )

which is implemented like

     def stub_new_authenticator( *args )
       result = mock(Authenticator, *args)
       Authenticator.stub!(:new).and_return(result)
       result
     end

I guess having something like that would be nice.
