[Haskell-beginners] Tests that use sample files in Cabal

Hi List, I'm trying to do my testing with HUnit and Cabal and I created a Test-Suite entry that runs when I do "cabal test" inside my project folder. My problem is that I want to add a second test case that needs to read a sample database file, I cannot include the file with Cabal's data-dir and data-files properties because it's only supported at the package level, this huge file will be always installed when doing "cabal install". Is there a standard way to access these files in a portable way? Any ideas? Thanks!
