Example

Here's what an example test.hs might look:

import Data.List
import Data.Ord
import Data.Tagged (Tagged)
import Data.Typeable (Typeable)
import Options.Applicative (switch, long, help)

import Test.Tasty
import Test.Tasty.Options
import Test.Tasty.Travis (travisTestReporter, defaultConfig)
import Test.Tasty.HUnit

newtype EnableTravis = EnableTravis Bool
  deriving (Eq, Ord, Typeable)

instance IsOption EnableTravis where
  defaultValue = EnableTravis False
  parseValue = fmap EnableTravis . safeRead
  optionName = return "enable-travis"
  optionHelp = return "Run Travis tests."
  optionCLParser =
    fmap EnableTravis $
    switch
      (  long (untag (optionName :: Tagged EnableTravis String))
      <> help (untag (optionHelp :: Tagged EnableTravis String))
      )

main = travisTestReporter cfg [] tests
  where
    cfg = defaultConfig { travisTestOptions = setOption (EnableTravis True) }

tests :: TestTree
tests = testGroup "Unit tests"
  [ testCase "List comparison (different length)" $
      [1, 2, 3] `compare` [1,2] @?= GT

  -- the following test does not hold
  , testCase "List comparison (same length)" $
      [1, 2, 3] `compare` [1,2,2] @?= LT
  , askOption $ \(EnableTravis enable) ->
    if enable then travisTests else testGroup "" []
  ]

travisTests :: TestTree
travisTests = testGroup "Travis" [ {- Travis tests here -} ]
