How can I find unused methods in a Ruby app?

refactoring

I have a Ruby app with a lot of classes/modules, and some of them are not used. Is there an easy way of finding out which?

I was thinking to do a profile, and then work with it's output. Any other ideas?

A coverage tool, like rcov might help.

As you find methods that are not covered by tests, you should write tests for them or find out if they are used at all.

Removing unused methods is part of refactoring, if you have too many classes that can be a code smell that needs refactored also.
