[rspec-users] Collection proxies need to be stubbed ?

[s.ross]

Do partial mocks solve your problem?

http://rspec.rubyforge.org/documentation/mocks/partial_mocks.html

I run into a lot of these issues when spec'ing, and it seems writing  
mocks that cover as many cases as I expect AR to cough up can be  
difficult. Others might have different experiences. I found partial  
mocks intriguing, although I've not yet explored them.

Hope I'm not barking up the wrong tree.
