Hi all,
I'm a huge fan of TDD (Test-Driven Development) et I used to use tools such as RSpec (Ruby). So naturally, I looked to HSpec, but it seems not idiomatic in Haskell. I have a bunch of questions: - Do you do TDD? - Which tools do you use? - Is doctest "better" (in some senses) than HSpec? Why? - Are HSpec and Doctest complementary? If so, in which case do you use one or another? - Is there some Haskell-specific good practices do to TDD?
In languages other than Haskell I do sometimes write tests first and practive real TDD. I Haskell writing test first seems a little ridculous. What I tend to do is: * Write the types. * Make sure the types interact together. * Fill in the functions. * For stuff that cannot be enforced by types, write tests. For tests I use Hspec (both canned example test and QuickCheck style property tests) but intend to start suplementing it with doctest so that example code in the docstring comments is tested for correctness.
