One of the questions that will arise once you start really using unit testing is “How much of my code is actually tested?”. iOS and CoverStory make determining this fairly simple.
During compile, setting the profile-arcs and test-coverage flags and including the libprofile_rt.dylib causes the compiler to generate gcov records that report statistics about test coverage.
CoverStory can then be used to display the information from those records. Refer to the instructions for CoverStory for details on how to download, install, and run CoverStory.
Now I need to investigate how to make this work when using GHUnit…
