ParamTree

BSD3 Hackage hackage-ci Build Status

ParamTree library for generating labelled test/benchmark trees from sets of parameters. Example usecases include criterion benchmark trees or tasty test trees.

Example

import Test.Tasty
import Test.Tasty.HUnit

genTestCase :: Int -> Bool -> Char -> String -> TestTree
genTestCase i b c name = testCase name $ {- your code here -}

params = simpleParam "Int" [1,2]
       . simpleParam "Bool" [True]
       . simpleParam "Char" "xyz"

main :: IO ()
main = defaultMain $ testTree genTestCase params
  where
    testTree = growTree (Just "/") testGroup "my tests"

This generates a tasty TestTree with all combinations of values passed to genTestCase. If the Maybe String argument is provided like in the above example, groups with a single entry, such as “Bool” get collapsed into their parent groups. So instead of a “1 Int” group containing a “True Bool” group they get collapsed into a single “1 Int/True Bool” group, where the “/” separator is the one specified by Just "/".
