Confusing statement concerning stubbing

[sdzivanovich]

Section 14.2: "Note that we can even stub methods that don’t exist, thus allowing us to not only test
classes that have errors."

This doesn't make much sense in the Java world of things, since you can only stub methods that are at least declared on the class/interface you're mocking. Maybe you can incorporate a Ruby example

Ugh, yup, that's not possible in Java (at least w/ Junit), although definitely with Ruby. I'll just mention "in other languages"
