Cabal - sharing datatypes

I have a top level file called Datatypes.hs. It's exposed in my cabal file.

library
    exposed-modules: Application
                     Foundation
                     Import
                     Settings
                     Settings.Development
                     Datatypes
                     Handler.Advise

I'd like to use Datatypes in my test code. Here's what I have tried

test-suite test type: exitcode-stdio-1.0 main-is: tests/testclient.hs hs-source-dirs: .,tests ghc-options: -Wall

build-depends: base
             , Datatypes
             , conduit == 0.5.2.7
             , attoparsec-conduit == 0.5.0.2
             , transformers == 0.3.0.0
             , resourcet == 0.4.0.2
             , http-conduit                  >= 1.5        && < 1.7
             , utf8-string == 0.3.7
             , aeson == 0.6.0.2

I still get complaints about datatypes in testclient.hs not being defined. Is what I am doing possible? For now I will just paste in my data types into testclient.hs, but I'd like to just be able to refer to Datatypes.hs

You can't list individual modules in the build-depends field - use the name of your package instead. For an example, look at the .cabal file for unordered-containers:

test-suite strictness-properties
  hs-source-dirs: tests
  main-is: Strictness.hs
  type: exitcode-stdio-1.0

  build-depends:
    base,
    [...]
    unordered-containers
