Here are four possible ways to use a pair of programmers in coding and unit testing a single subprogram from a given design: Share: They work together on the programming and testing, sharing the work roughly equally. Separate: They program independently, creating two versions of the code, which are run against each other for unit test. Inspect: One does the programming, and the other inspects the resulting code for defects. There is no unit test. Test: One does the programming, and the other does unit testing of the resulting code. Rank these, first: By how quickly the work is completed; and second: By the reliability of the resulting code. Justify your rankings briefly.
