test-framework-th
contains two interesting functions: defaultMainGenerator
and testGroupGenerator
.
defaultMainGenerator
will extract all functions beginning with case_, prop_ or test_in the module and put them in a testGroup.
-- file SomeModule.hs
( -# LANGUAGE TemplateHaskell #- )
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
( -# LANGUAGE TemplateHaskell #- )
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).
