cabal test and detailed-0.9 strangeness
by Daniel Peebles 10 Jan '11

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

Let me know if you agree; I > just don't want to waste your time by submitting a misguided patch. I'm slightly reticent to add it to the TestSuite bit itself because it's mixing two things: a static description of the package, with status tracking within the build system. That said, there's not an obvious place to put it that exists all the way through the dep resolution stage. If it were just later on then we could add something to the LocalBuildInfo. Give it a go, but add a TODO note suggesting the status info might be better to live somewhere else. We might be able to do it better when we next overhaul the GenericPackageDescription -> PackageDescription resolution stuff. Duncan

I suggest we add a configure flag `--enable-test-coverage` that: * adds `ghc-option: -fhpc` to all libraries, * runs the `cabal test` binaries in some working directory other than the root to not clutter it with .tix files, * runs `hpc <test-suite-binary.tix> --destdir=dist/SOMETHING` on all .tix files, and * prints the location of the HTML index files to stdout. We might want to opt-out the test suite's `main-is` file from the report. Perhaps using a flag. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/467#comment:3> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

There are several similar functions in `Cabal`. Cabal ought to also say what it was running and what the error code was, without needing a verbosity flag to be given. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/786> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

[Hackage] #784: Cabal strips out { and } in literate code blocks of the description field

#784: Cabal strips out { and } in literate code blocks of the description field ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- If you have a description like this: {{{ description: Here is some C code: . > for(i = 0; i < 100; i++){ > printf("%d\n",i); > } . }}} Cabal will strip out the brackets. You can use @..@ syntax with { and } except that then the whitespace is off in your code block and you have to escape any symbols that haddock knows. Putting a blackslash (\) in front the braces does not help. The above example works fine in plain haddock leading me the conclusion that cabal is eating the braces. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/784> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
