Posted on behalf of Duncan Beevers http://rubyforge.org/users/dunca... from post on mailing list http://rubyforge.org/pipermail/m...

I really like the idea of Mock Proxies as explained in Brian Takita's post here: http://pivots.pivotallabs.com/us...

I posted to this list eariler with an incomplete implementation of stops_mocking in the thread "Mocking Time, delegating to original object." http://rubyforge.org/pipermail/m... The Mock Proxy pattern would make this simpler.

Proxy(User).expects(:find).with(99) # Sets expectation, forwards method invocation to original class

User.expects(:find).with(99).returns(nil).then.proxies # Canned response, then forwards successive invocations to original class.

Most of this is just my desire to be lazy and not actually have to unit-test trivial methods explicitly. I also like the idea of using the Mock Proxy to exercise the behavior of simple private instance methods of my class which are kind of a pain to test currently, which leads to my not making anything private.
