This might be a shot in the dark but does anyone know how to test error handling in Rails? Say for example you have a method that has a begin block with 10 lines of code in it and a rescue that does some logging or does a puts statement. How do you write a spec that tests the code within the rescue automatically without modifying the 10 lines of code? My google-fu on this one has failed.

I'm probably misunderstanding your situation, but why don't you (from the test suite) mock some function used in the begin block to throw an error and then `expect(the_logging_function).to have_received` the logging output?

That's not actually a bad idea at all. What however if you're just doing simple variables manipulations in those 10 lines and not calling methods (I realize that you can override the math methods as well)? Is there a way to handle that easily or inject an exception into the begin block?
