Question

I have a class defined using theClass.class_eval and Object.const_set(className, theClass). Is there any way to remove the definition of this class? During testing I need to load different versions of the same class.

Answer 1

Object.send(:remove_const, className) did the trick.

Answer 2

I see that doing Object.send(:remove_const, className) prevent to reload the same class..

how to reload?
