Hi,

I am writing tests for a Rails app using Test::Unit and Mocha. expects  
does a great job to make sure a method is called. But how to handle the  
fact that a method shouldn’t be called?

I have a before filter that protects the call to a given restricted  
method, and how to make sure that this method doesn’t get called  
unexpectedly?
