If your library code and test code are in separate sub-directories and
you reference your library as a package dependency for your test then
Cabal won't re-build your library.

That is, the 'Hs-source-disr' for the library and the test should not
overlap. Otherwise GHC will compile the file-on-disk instead of
grabbing the module from a package.
