| Video Discription | NASA's tech fellow, Dr. Lorraine (Lore) Prokop describes what software unit testing is, why to unit test, and demonstrates how to do MC/DC unit testing with gcov. The form of unit testing performed is MC/DC (modified condition/decision coverage) testing which is required for safety-critical systems, though recommended for all software. It tests the minimum set of meaningful logical paths through a unit of code.
