Coming in JMP Pro 12: Four great features of Covering Arrays

Covering arrays are a powerful design tool that may be used to design test cases to efficiently test deterministic systems. For such systems, a particular input will always generate the same output and, as a result, standard statistical designs are usually inefficient. It turns out that failures in these systems
