Abstract

Under certain well defined conditions, the stream X-machine testing method can produce a test set that is guaranteed to determine the correctness of an implementation. The testing method has originally assumed that an implementation of each processing function or relation is proven to be correct before the actual testing can take place. Such a limitation has been removed in a subsequent paper, but only for deterministic X-machines. This paper extends this result to non-deterministic stream X-machines and considers a conformance relationship between a specification and an implementation, rather than mere equivalence. Furthermore, it shows how this method can be applied to test a P system by building a suitable stream X-machine from the derivation tree associated with a partial computation.
