Detecting whether a class has a definition for a method or not changes between Ruby 1.8 and Ruby 1.9. We introduce the "flexmock_defined?" method on class objects to have a portable way to determine that.
NOTE: responds_to? isn't appropriate. We don't care if the object
responds to the method or not. We want to know if the class has a definition for the method. A subtle difference.
Does a class directly define a method named "method_name"?
