Homer said in Iliad
...there is no man that shall catch thee by a burst of speed, neither pass thee by, nay, not though in pursuit he were driving goodly Arion, the swift horse of Adrastus, that was of heavenly stock... Homer
Arion helps you make red-green-refactor quick and efficient when working with hspec tests
It watches the file system for change in source or test code and selectively runs hspec tests by creating an association between source and test files
cabal update
cabal install arion
arion [folder-to-watch] [folder with source files] [folder with test files]
