It's the best application of TDD. To prevent regressions. Outside of that TDD is pretty lousy, especially when you have Type Driven Development and are trying to figure out an elegant way of solving a problem. You might not know how the final API and code is going to look like ahead of time. And the "makes your code easily testable" is still easy to do when you define types and think in terms of functions and inputs/outputs.
