Cabal Test Suite with type detailed example

Question

I'm searching for a cabal package using the detailed Test-Suite interface to learn how to structure the code.

Answer 1

The cabal documentation contains examples for both the detailed-1.0 and exitcode-stdio-1.0 test interfaces. However, note that the detailed test interface isn't supported yet. Only the simpler exitcode-stdio-1.0 interface is currently supported.

From a recent mail thread on the cabal-devel list (dated September 5, 2011):

Ah, a rare case of premature documentation. That is, documentation for a feature that is due, but not released yet. [...] No released version supports the detailed interface yet. Just recently we think we've settled on the final interface and will hopefully get that implemented in the darcs version soon.

Answer 2

Since I have been stumbling over this question quite a few times: With Cabal 1.20(1.18 ?), detailed-0.9 is supported, see for example https://github.com/michaxm/test-detailed-example. But since there has been quite some time witout it, the infrastructure around exitcode-stdio-1.0 (+ one of the supporting libs, e. g. hspec, hunit, ...) may still be superior.

See How to use detailed-0.9 in cabal testing as well.

Example of minimal .cabal contents for a detailed-0.9 test (using names of a default stack project) :

name:                test-detailed-example
version:             0.1.0.0
build-type:          Simple
cabal-version:       >=1.20

library
  hs-source-dirs:      src
  exposed-modules:     Lib
  build-depends:       base >= 4.7 && < 5
  default-language:    Haskell2010

test-suite test-detailed-example-test
  type:                detailed-0.9
  hs-source-dirs:      test
  test-module:         Spec
  build-depends:       base >= 4.7,
                       Cabal >= 1.20
  default-language:    Haskell2010

Answer 3

Haddock's cabal file includes a test-suite stanza; perhaps you could start there.
