While previously browsing through some information on unit testing in Xcode 4, I noticed some issues from people looking to obtain the code coverage data for their unit tests in Xcode 4. For those unfamiliar with the term code coverage – it is a measurement of how much of your source code is being tested when you do your testing.
Recently, I received a submission for an excellent tutorial demonstrating how to generate and display the GCOV coverage data, and how to improve the coverage of your unit tests.
The tutorial is from Claus Broch and can be found here:
Covering It All Up
Claus recommends using the open source Cover Story application to get a better look at your code coverage data.
If you’re doing any unit testing in Xcode 4 this is a measurement you will definitely want to have.
