I recently installed stack via Haskell for Mac OS X (https://ghcformacosx.github.io/), which gave me stack 0.1.8.0 x86_64 and ghc 7.10.2. Following the User Guide (http://docs.haskellstack.org/en/stable/GUIDE.html), I tried to create the first example (hello world, naturally). Everything went according to plan until I entered 'stack test', which failed. The output was supposed to be, 'Test suite not yet implemented.' I tried to find information online, but was unsuccessful. I play with Haskell for fun and know nothing about cabal, so I don't know if it is a cabal issue. The error message includes 'helloworld-test: executable not found'. helloworld-test is indeed missing. I searched for it using find: find . -name '*test' Here is the terminal session, followed by the contents of the generated helloworld.cabal file (with some user info removed): $ stack new helloworld new-template Downloading template "new-template" to create project "helloworld" in helloworld/ ...

Hi Robert,
The reason for the "Test suite not yet implemented" message is that this is
the default behaviour of the test suite that comes with "new-template":
$ cat test/Spec.hs
main :: IO ()
main = putStrLn "Test suite not yet implemented"
BTW, stack 0.1.8.0 is fairly outdated by now, so try to run "stack upgrade".
Cheers,
Simon
