> ... start coding without a plan ... Well, I don't do that. But i usually don't know all the names of my (internal) interfaces and models and properties right at the start. I might move things around and rename stuff along the way. And I think that's quite normal if you don't live in a world where the spec for a small task is multiple books thick. Doesn't TDD get in the way with? Wouldn't I keep refactoring the tests all the time then?
