Also, in the build phases, in the Compile Sources phase, make sure you added the relevant implementation files. I met this problem when I wrote GHUnit tests for classes that lived in a target that had all the implementation files in the compile sources phase, while the GHUnit tests classes target didn't have the implementation files in the compile sources phase. Thank you! – nurne Feb 7 '12 at 18:15
