convert a custom test-suite to Cabal-test
by Henning Thielemann 14 Mar '11

14 Mar '11

Currently I am trying to convert the test suite in utility-ht to Cabal's new Testing feature. The documentation in http://www.haskell.org/ghc/docs/7.0.2/html/libraries/Cabal-1.10.1.0/Distrib… mentions the packages cabal-test-hunit, cabal-test-quickcheck1, and cabal-test-quickcheck2 but I cannot find them on Hackage. Will I be able to write a test-suite that works both with QuickCheck-1 and QuickCheck-2? So far I was able to write my Arbitrary instances and tests in a way that they can be run from both QuickCheck-1 and QuickCheck-2. Thus a single package cabal-test-quickcheck that provides a consistent interface to both QuickCheck versions would help me. I am unhappy about the naming PureTestable vs. ImpureTestable. As part of a fundamental package like Cabal it further fixes the ubiquitous confusion about purity in Haskell. I propose to rename as follows: ImpureTestable -> IOTestable PureTestable -> SimpleTestable or BoolTestable

[Hackage] #812: setup.exe: internal error: unexpected package db stack: [UserPackageDB]

I get the error: {{{ > cabal install cairo --ghc-option=-DCABAL_VERSION_MINOR=10 ... Registering cairo-0.12.0... setup.exe: internal error: unexpected package db stack: [UserPackageDB] ... }}} The CABAL_VERSION_MINOR flag is suggested if you try without it but doesn't make a difference in the outcome.

Re: [Hackage] #179: support GHC's main-is extension

#179: support GHC's main-is extension ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: low | Milestone: _|_ Component: Cabal library | Version: 1.2.2.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.4.2 Platform: Linux | ----------------------------+----------------------------------------------- Comment(by cjs): Right. Note that while the same source file can be used both as a "Main" file and a library file by using or not the --main-is option, changing that switch produces different object files. Thus, if you are using a file for both purposes (e.g., a library module that also includes a main used as part of a test system, because it needs access to stuff you'd rather not expose to the library users) you'll need to compile your two versions to two separate locations. I solved this in my build system by having a separate directory for interface and object files compiled with --main-is. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/179#comment:11> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
