Error creating test suites: "cannot satisfy -package-id"

Question

I am trying to create a test suite for my HaskSplit project in my .cabal configuration:

 -- Initial HaskSplit.cabal generated by cabal init. For further -- documentation, see http://haskell.org/cabal/users-guide/ name: HaskSplit version: 0.1.0.0 synopsis: Haskell Implementation of Shamir Secret Sharing Scheme -- description: license: MIT license-file: LICENSE author: maintainer: -- copyright: category: Security build-type: Simple -- extra-source-files: cabal-version: >=1.10 executable HaskSplit main-is: Main.hs default-language: Haskell2010 -- other-modules: other-extensions: TemplateHaskell, NoImplicitPrelude, RankNTypes, OverloadedStrings build-depends: base >=4.6 && <4.7, resourcet >=1.1 && <1.2, bytestring >=0.10 && <0.11, conduit-extra >=1.1 && <1.2, vector >=0.10 && <0.11, conduit >=1.1 && <1.2, conduit-combinators >=0.2 && <0.3, mono-traversable >=0.5 && <0.6, safe >=0.3 && <0.4, transformers >=0.3 && <0.4, filepath >= 1.3, directory >=1.2, Glob >= 0.7.4, errors >= 1.4, optparse-applicative >= 0.8 hs-source-dirs: src default-language: Haskell2010 ghc-options: -Wall -fno-warn-orphans test-suite tests type: exitcode-stdio-1.0 default-language: Haskell2010 hs-source-dirs: tests main-is: Test.hs ghc-options: -Wall -fno-warn-orphans build-depends: base == 4.*, QuickCheck >=2.6 && <2.7, test-framework-quickcheck2 >= 0.3.0.3, HaskSplit 

Looking at the test suite installation example here , I noticed that they define their own package as one of the assembly-dependent modules. So I did the same, so that I can keep the build-depends list for my test suite shorter.

However, when I try cabal repl test:tests on the command line, I get the following error:

 <command line>: cannot satisfy -package-id HaskSplit-0.1.0.0-inplace 

I'm not too sure what I'm missing here, can someone help me? Are these cyclic dependencies occurring here? Or do I need to create an instance of my package library for assembly - depends on the job?

Thanks!

Answer 1

The build-depends section can only contain libraries, not modules. I suggest you add the library to your cabal file. The exposed-modules section of the library should list all the modules that may be required for your test (or any other library user).

As an alternative to creating a library, you can simply add the modules you need to part of the other modules in the test suite section. However, if you want to include many modules, I think the library approach is more pleasant.

After some tweaking, here is what I got, for completeness:
