How to specify an "interface"?

[XSven]

Reading this

Test::MockObject allows you to create objects that conform to particular interfaces with very little code.

I am asking myself how can I tell a Test::MockObject instance what is the interface that I am going to mock completely or partially?

To me an interface is a list of method names. To avoid creating a mock that refers to a method that does not belong to a given interface I would like to define my interface first. Test::MockModule provides the strict mode sefety net. Yes I know the scope of Test::MockModule is a given class and not an interface but the problem is the same.

For the time being I have used

set_false(name_1, name_2, ... name_n)

to tell a Test::MockObject instance to provide dummy implementations for an interface that covers the methods name_1, name_2, ... name_n.
