HTF - The Haskell Test Framework

Build Status Hackage


The Haskell Test Framework (HTF for short) lets you define and organize unit tests (, QuickCheck properties (, and black box tests in an easy and convenient way. HTF uses a custom preprocessor that collects test definitions automatically.

HTF produces highly readable output for failing test cases: it provides exact file name and line number information, it colors and pretty prints expected and actual results, and it displays a diff highlighting the mismatching parts.

Getting started

  • Read the tutorial.
  • Experiment with the sample project located in the sample directory of HTF’s source tree.
