#assit_quack(object, methods, message = "Quack assert failed.") ⇒ Object

Duck typing assertion: This checks if the given object responds to the given method calls. This won’t detect any calls that will be handled through method_missing, of course.

Methods can be a single method name, or an Enumerable with multiple names
