Unit testing with network-reliant code

Question

I\'m trying to be better about unit testing my code, but right now I\'m writing a lot of code that deals with remote systems. SNMP, WMI, that sort of thing. With most classes

Answer 1

The easiest way to test things which are hard to mock is to refactor the code in the way that your code (logic which is worth testing) is in one place and other things which your code use are in separate module(s). The module is easy to mock and this way you can focus on your business logic.
