Hi, I've been playing with the detailed-0.9 test-suite option on a package of mine. First, what I have: in my package root, I have my .cabal file and a tests folder containing a Tests.hs in my Tests.hs, I took the code from the online user guide (minus the odd guards with == True and == False): {-# LANGUAGE FlexibleInstances #-} module Tests ( tests ) where import Distribution.TestSuite instance TestOptions (String, Bool) where name = fst options = const [] defaultOptions _ = return (Options []) check _ _ = [] instance PureTestable (String, Bool) where run (name, True) _ = Pass run (name, False) _ = Fail (name ++ " failed!") test :: (String, Bool) -> Test test = pure -- In actual usage, the instances 'TestOptions (String, Bool)' and -- 'PureTestable (String, Bool)', as well as the function 'test', would be -- provided by the test framework. tests :: [Test] tests = [ test ("bar-1", True) , test ("bar-2", False) ]
in my .cabal file: Test-Suite binutils Hs-source-dirs: tests/ Type: detailed-0.9 Test-module: Tests Build-depends: base, Cabal >= 1.9.2
I then run cabal configure --enable-tests and finally run cabal test. It gives me this: Running 1 test suites... Test suite binutils: RUNNING... Test suite binutils: PASS Test suite logged to: dist/test/charm-0.0.1-binutils.log 1 of 1 test suites (0 of 0 test cases) passed.
Which seems odd, since there are 2 test cases (not 0 as the output claims) and one of them should definitely be failing (it has a False in it). Am I doing something wrong? Thanks, Daniel
Duncan and I made the decision to turn off the detailed type in the current release because it's not totally ready. You should get a warning to that effect when you run 'cabal configure --enable-tests' with a detailed-type test. Your tests are not actually passing; they're not even running, but Cabal is failing to produce a useful error message. This is at the top of my to-do list (though I realize that may be little consolation for your wasted time now). Short version: you've done nothing wrong. (Mea culpa.) This should be fixed soon. -- Thomas Tuegel
