This documents my foray into Haskell programming. My functional programming language of choice is, for the moment, Racket (specifically Typed Racket), and while I’ve always been interested in Haskell, I’ve never taken the time to learn it properly.

Writing controller specs for a Warp server
This guide will show you how to configure a Cabal project to test a Warp server (such as Scotty or Yesod) using hspec2. It will allow you to test HTTP requests and responses and to prepare the database before/between steps. directories and cabal Assuming your project code lives in a top-level src directory, create another top-level directory called test. We need to add a new section to the project
