Abstract

The introduction of multiple remote testers to apply a test or checking sequence introduces the possibility of controllability and observability problems. These problems can require the use of external coordination message exchanges among testers. It is desirable to construct a test or checking sequence from the specification of the system under test such that it is free from these problems without requiring the use of external coordination messages. Here we define criteria on the specification of the system under test for this to be possible. For specifications satisfying the criteria, algorithms for constructing subsequences that eliminate the need for external coordination messages are given.
