TDD …how?

Question

I\'m about to start out my first TDD (test-driven development) program, and I (naturally) have a TDD mental block..so I was wondering if someone could help guide me on where

Answer 1

Your split sounds reasonable. I would consider the two dependencies to be the input and output. Can you make them less dependent on concrete production code? For instance, can you make it read from a general stream of data instead of a socket? That would make it easier to pass in test data.

The creation of the return value could be harder to mock out, and may not be a problem anyway - is the logic used for the actual population of the resulting object reasonably straightforward (after the parsing)? For instance, is it basically just setting trivial properties? If so, I wouldn't bother trying to introduce a factory etc there - just feed in some test data and check the results.
