Yeah, that's why I want to set it up. However, I don't want the setup
In my Cabal file I have a flag which controls whether the test
executable gets built or not:
Main-Is : Main.hs
Hs-Source-Dirs : test_src src
Ghc-Options : -threaded
Build-Depends : HUnit, network
Buildable : True
Ghc-Options : -fhpc
Buildable : False
The main reason for this is that the test executable depends on some
packages that would never be used in the main part of the package. I
not want my Setup.hs to depend on those packages.
In my Setup.hs I then define the following test hook:
runTestsBuild a b pd lbi = let
doWithExe e _ = let
_exe = "./dist/build/" ++ (exeName e) ++ "/" ++
_runTest = do
putStrLn $ "** " ++ (exeName e) ++ ":"
ig $ system _exe
when (exeName e `elem` ["utest"]) _runTest
(runTests simpleUserHooks) a b pd lbi
withExeLBI pd lbi doWithExe
And this is where the issue I *asked* about comes in. The building of the
test executable is controlled by the flag Test, but the flag doesn't seem to
be available in the test hook so instead I have to rely on the name of the
