The Value Premise | #101

PawCast with GeePaw Hill

Today it's microtest TDD's Value Premise: TDD ships more value faster when that value depends on changing our branching logic safely & quickly. Let's dig in. I am frequently presented with declarations that TDD is fine for plebs like me, but useless for software of type X. I've heard every variety of app type or coding specialty or domain substituted for that X. In other parts of the forest, I hear that the purpose of TDD is high quality, and if you don't care about that, you don't need TDD. Or that it's for satisfying personal or professional ethics, and if you don't care about that you don't need TDD and you're a bad person. The Value premise says that TDD is an instrument for productivity, and its effectiveness depends on how much of our work requires us to change our branching logic, which it lets us do with greater speed and lower risk than non-TDD methods.
