This paper looks at the formal analysis of Z specifications in order to enhance the testing process. An algorithm is given that rewrites the specification to a form from which both a partition of the input domain and the states of a finite state automaton model can be derived. Test cases can be derived from the former and an automated system to control the testing process can be based upon the latter. © 1997 by John Wiley & Sons, Ltd.
