Ruby -> Haskell Unit and Automated Acceptance Testing

Question

I'm a programmer with a background in many languages, but most recently focused on Ruby/Rails and interested in learning some Haskell. I've done a bit of playing around in Closure as well (pretty basic stuff though).

My current preferred approach to developing a new Ruby application is to start with high-level tests in business-value language using something like Gherkin/Cucumber and then develop smaller-scale components using something like RSpec or Minitest. What is (currently) the most common similar tool-set and strategy for developing a new Haskell application?

Responders: Please be patient waiting for up-votes & answer acceptance from me. I'll have to actually do some work in Haskell in order to make any assessments. Thanks.

Typically the source of truth in a Haskell app is the type system. You use quickcheck and hspec to increase assurance that your code does what you think, but it's just an aid.
