Abstract
A fault-tolerant protocol is defined by the exchange of messages providing correct results to those units which are free of operation faults. We propose a hierarchical test strategy with heuristic fault case generation at the message layer to test whether a fault-tolerant protocol is able to tolerate the pre-defined faults. Messages sent by faulty units are replaced by heuristically generated fault cases which intend to cover all program paths of the faultless protocol units subsequently. Since this well-aimed fault case generation induces complex problems, we use special characteristics of fault-tolerant protocols to reduce the complexity. In this paper we outline our hierarchical test strategy and explain the heuristic fault case generation in detail. The test strategy is being implemented on a network of Macintosh computers.
