test-framework-th-0.1.3: Automagically generate the HUnit- and Quickcheck-bulk-code using Template Haskell.

The test-framework-th package

test-framework-th contains two interesting functions: defaultMainGenerator and testGroupGenerator.

defaultMainGenerator will extract all functions beginning with case_ or prop_ in the module and put them in a testGroup.

 -- file SomeModule.hs
 ( -# OPTIONS_GHC -fglasgow-exts -XTemplateHaskell #- )
 module SomeModule where
 import Test.Framework.TH
 import Test.Framework
 import Test.HUnit
 import Test.Framework.Providers.HUnit
 import Test.Framework.Providers.QuickCheck2

 -- observe this line!
 main = $(defaultMainGenerator)
 case_1 = do 1 @=? 1
 case_2 = do 2 @=? 2
 prop_reverse xs = reverse (reverse xs) == xs
    where types = xs::[Int]

is the same as

 -- file SomeModule.hs
 ( -# OPTIONS_GHC -fglasgow-exts -XTemplateHaskell #- )
 module SomeModule where
 import Test.Framework.TH
 import Test.Framework
 import Test.HUnit
 import Test.Framework.Providers.HUnit
 import Test.Framework.Providers.QuickCheck2

 -- observe this line!
 main =
   defaultMain [
     testGroup "SomeModule" [ testCase "1" case_1, testCase "2" case_2, testProperty "reverse" prop_reverse]
     ]

 case_1 = do 1 @=? 1
 case_2 = do 2 @=? 2
 prop_reverse xs = reverse (reverse xs) == xs
    where types = xs::[Int]

testGroupGenerator is like defaultMainGenerator but without defaultMain. It is useful if you need a function for the testgroup (e.g. if you want to be able to call the testgroup from another module).
