I have an existing iPhone app, written in Objective-C, that I'd like to add some automated tests to. I've read this article about testing with MacRuby, which sounds great but it's aimed at testing desktop frameworks.
How can I add MacRuby tests to my iPhone app? The Ruby code doesn't recognize my Objective-C classes, and I don't know how to set it up to do that. Do I need to somehow point it at the compiled code or the headers?
