Find unused code in a Rails app

Question

How do I find what code is and isn\'t being run in production ?

The app is well-tested, but there\'s a lot of tests that test unused code.

Answer 1

It is not the perfect solution, but for example in NetBeans you can find usages of the methods by right click on them (or press Alt+F7).
So if method is unused, you will see it.
