Abstract-Given the large number of possible fault scenarios,
complex control systems are usually impossible to test
exhaustively. One promising approach, however, is
evolutionary testing (ET) in which a genetic algorithm (GA)
evolves critical test situations. We evolved challenges (pipe
rupture and water demand) to the valve and pump controls of
a shipboard firemain system. ET found minor events that
collectively produced significant systen failure, and also
identified a modification to the ship design that improved
system performance. ET can also be used to map the
boundary of search space for a given, user-defined criterion.
The potential of this powerful, generic technique not just for
testing but also for system redesign is thus emphasized.
