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

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).
