Tasty Travis: Fancy Travis CI output for tasty tests

Tasty Travis provides fancy Tasty test output on Travis CI.

It allows you get coloured test output, folding and collapsing groups of tests, and hiding the output of successful tests.

Example

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

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

import Data.List
import Data.Ord

main = defaultMainWithIngredients ingredients tests
  where
    ingredients = [ listingTests, travisTestReporter defaultConfig ]

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
  ]
