Series of posts on testing Haskell code

2009-01-17, 15:04

I’ve been using both QuickCheck and HUnit to make sure that the functions in dataenc both have the expected properties and follow the specifications.

This morning I stumbled on a series of posts by Matthew Podwysocki on Functional Programming Unit Testing (part 1, part 2, part 3, part 4, part). I think I really could have used these posts about two years ago when I first ventured into the world of testing Haskell. The only new thing I learnt was the existance of the package test-framwork in parth three. Anyway, they are a good introduction to testing Haskell code (and F#).

Useful thing when adopting test-framework after already using HUnit

2009-01-17, 14:53

I found test-framework today. In adopting it with my already existing unit tests I found this function to be rather useful:

import Test.HUnit
import qualified Test.Framework.Providers.API as TFAPI
 
unitTest2TFTest :: Test -> [TFAPI.Test]
unitTest2TFTest t = let
        unitTest2TFTest' desc (TestCase a) = [testCase desc a]
        unitTest2TFTest' desc (TestLabel s t) = unitTest2TFTest' (desc ++ ":" ++ s) t
        unitTest2TFTest' desc (TestList ts) = concat $ map (unitTest2TFTest' desc) ts
    in unitTest2TFTest' "" t
