Re: [Rubycocoa-talk] Unit Testing Objective-C classes with RubyCocoa

[Eloy D. <e....@su...>]

Hi Rod,

Not sure where the overriding of #chomp happens and/or that's supposed  
to happen...?
But anyways, if you want to be able to override stuff without RC  
complaining about
the arity you should do the following somewhere before you start your  
tests:

def OSX._ignore_ns_override; true; end

Cheers,
Eloy
