Abstract

Deterministic execution testing has been considered a promising way for concurrent program testing because of its ability to replay a program's execution. Since, however, deterministic execution requires that a synchronization event sequence to be replayed be feasible and valid, it is not directly applicable to a situation in which synchronization sequences, being valid but infeasible, are taken into account. Resolving this problem is very important because a program may still meet its specification although the feasibility of all valid sequences is not satisfied. In this paper, we propose a new deterministic execution method that permits synchronization sequences other than a given (possibly infeasible) sequence to be executed if they have the same effects on the program's behavior. One major advantage of this method is that it can be applied to situations where a program is not exactly implemented as described in the specification.
