Test driven development is hard. Perhaps it would not be if we were taught to think about OO development from a TDD perspective in the first place; but those muscles are poorly developed, and the exercise leaves you sore and panting a bit. As with physical exercise, there is a reward in the pain. Perhaps others do not see it, but I can already see the benefits accruing in Reggie as I rebuild it with SOLID principles in mind, driven by tests. To help me consolidate where I’m going, and help others whose TDD muscles are likewise under-developed, let us walk through a test, shall we?

For several years now, I have been relying on Microsoft’s Moles for isolating one method from another in my unit tests. Recently I’ve begun to understand that this was not the best approach. I’ll dig into that more in a future post. Having come to this conclusion, I need to start ripping out Moles. Based on the user feedback across the web, and the powerful Lambda expression syntax I’ve grown used to, I’ve chosen MoQ as my replacement. Now for an exercise…
