In my Cabal file I have defined a flag that controls whether tests are built or not. Now I'd like to hook it up a bit more so that './Setup.hs test' actually runs the tests.

This will allow you to issue 'cabal test' to run the test suite, but it may introduce other issues. I suspect that this won't work well with dependencies or language extensions defined in the cabal file -- I'm really not sure, as I haven't actually done this in "real" code. I just wanted to see if it would work a few months back.

Yeah, that's why I want to set it up. However, I don't want the setup you suggest. In my Cabal file I have a flag which controls whether the test executable gets built or not: Executable utest Main-Is : Main.hs Hs-Source-Dirs : test_src src Ghc-Options : -threaded if flag(Test) Build-Depends : HUnit, network Buildable : True Ghc-Options : -fhpc else 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 also do 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) ++ "/" ++ (exeName e) _runTest = do putStrLn $ "** " ++ (exeName e) ++ ":" ig $ system _exe in when (exeName e `elem` ["utest"]) _runTest in do (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 executable. /M
