Dear reader, I have a single executable package in Cabal[1] and I have added a test for it using an example configuration from the ltc package[2]. With my test on my executable I can't depend on the main package, but I seem to have to repeat the dependencies of my executable, or split off functionality into a library. [3] Can I easily depend on the dependencies of another package or should I create a library and depend on that in my test and executable?
