Re: [Haskell-cafe] HSpec vs Doctest for TDD

That's true. I'm not stating tests aren't necessary; I'm stating TDD isn't necessary. You write tests, but you don't START with writing tests. Отправлено с iPad

Well, for me TDD seems to be a poor substitute for type safety.

And I specifically mean the level of type safety Haskell provides. In other languages TDD could be a good thing (although I value explorative programming too much), but in Haskell I think it's a waste of time.

Type safety does not cover everything; nearly an infinite number of functions could be made with the type: f :: Int -> Int

To paraphrase prof. Edsger W. Dijkstra: No amount of type checking will prove a program correct
