- Synopsis
- The Haskell Test Framework
- Description
The Haskell Test Framework (HTF for short) lets you define unit tests (http://hunit.sourceforge.net), QuickCheck properties (http://www.cs.chalmers.se/~rjmh/QuickCheck/), and black box tests in an easy and convenient way. HTF uses a custom preprocessor that collects test definitions automatically. Furthermore, the preprocessor allows HTF to report failing test cases with exact file name and line number information. Additionally, HTF tries to produce highly readable output for failing tests: for example, it colors and pretty prints expected and actual results and provides a diff between the two values.
The documentation of the Test.Framework.Tutorial module provides a tutorial for HTF. There is also a slightly out-dated blog article (http://factisresearch.blogspot.de/2011/10/new-version-of-htf-with-diffs-colors.html) demonstrating HTF's coloring, pretty-printing and diff functionality.
HEADS UP, backwards incomatibility with prior versions:
In version 0.10.0.0, the following changes could break code compiled against version 0.9.*:
Test.Framework now longer exports all of Test.Framework.TestManager and Test.Framework.BlackBoxTest. For modules that only define tests, no changes should be necessary. However, you likely need to adjust your test runner module by importing Test.Framework.TestManager and possibly Test.Framework.BlackBoxTest.
Some reorganization in Test.Framework.TestManager and related modules, introduction of Test.Framework.TestTypes. Usually, your code should not be affected by these changes.
Starting with version 0.9.0.0, HTF uses a new strategy for collecting the testcases defined in your project (see Test.Framework.Tutorial for a description of this strategy). If you used version 0.8.* or earlier of HTF, this will break your build! However, it's rather easy to bring you project in line with the new HTF version. Here are the steps that will most likely resolve your backwards incompatibility problems:
If a module exports the
allHTFTestssymbol, this export must be changed tohtf_thisModulesTests.If an import declaration of some module hides the
allHTFTestssymbol, you can simply remove the hiding clause forallHTFTests.If a module collects and executes tests from several other modules, the collecting module has to be changed as follows: add
{-# OPTIONS_GHC -F -pgmF htfpp #-}to the top of the collecting module, import the other modules with the{-@ HTF_TESTS @-}annotation, use the symbolhtf_importedTestsfor referencing the imported tests. See Test.Framework.Tutorial for details.
