I have a Haskell project with a test suite using detailed-0.9
. I can run the test correctly with cabal
, but with stack
I get errors. The exitcode-stdio-1.0
test suites seem to work fine.
MWE
Below is a minimum working example, containing both test-suite types. A full repository is available here.
stack-test-detailed.cabal
name: stack-test-detailed
version: 0.1.0.0
build-type: Simple
cabal-version: >=1.20
test-suite exitcode
type: exitcode-stdio-1.0
main-is: Exitcode.hs
other-modules: MyModule
build-depends: base >=4.10
hs-source-dirs: src testsuite
default-language: Haskell2010
test-suite detailed
type: detailed-0.9
test-module: Detailed
other-modules: MyModule
build-depends: base >=4.10, Cabal >=1.20
hs-source-dirs: src testsuite
default-language: Haskell2010
src/MyModule.hs
module MyModule where
myFunction :: Int
myFunction = 1
testsuite/Exitcode.hs
import MyModule (myFunction)
import System.Exit (exitSuccess, exitFailure)
main :: IO ()
main =
if myFunction == 1
then exitSuccess
else exitFailure
testsuite/Detailed.hs
module Detailed where
import MyModule (myFunction)
import Distribution.TestSuite
tests :: IO [Test]
tests = return
[ Test $ TestInstance
{ run = return $ Finished $ if myFunction == 1 then Pass else Fail "not equal 1"
, name = "my test"
, Distribution.TestSuite.tags = []
, options = []
, setOption = \opt val -> Left "options not supported"
}
]
stack.yaml
resolver: lts-11.22

Exitcode test works:

Detailed test fails to compile:

From looking around I gather that detailed-0.9
is somehow uncool and people just seem to give up on it immediately. But it is properly documented and indeed works with cabal
, so I don't see why stack
should fail with it.
