My apologies, but how to test using Test::MockObject seems simple according to the documentation. Where I fall down however is what and how to test in context.

Testing an object that munges text or does calculations is pretty straight forward I would think. You know the in and out going into the test. But what about a network client in which there isn't one method to test, but instead it's the whole connect/send/receive/disconnet conversation that needs to be tested? It is at that point that I don't understand or have a clue where to start, esp without a server to conect to or a mock server to use.
