How do you unit-test a TCP Server? Is it even worth it?

Question

I\'m developing a small TCP server, which will process some TCP packets and behave differently based on the request.

How can I write unit test for this? If it\'s really

Answer 1

You might take a look at NMock, a mocking library for .NET. If two parties are involved in a unit-test it's always good to just "mock" one party (the one you are not testing, in that case the Client).

This will however require some changes to your code, but believe me, it's worth it.
