Testing conformance of a deterministic implementation against a non-deterministic stream X-machine

Testing conformance of a deterministic implementation against a non-deterministic stream X-machine

Stream X-machines are a formalisation of extended finite state machines that have been used to specify systems. One of the great benefits of using stream X-machines, for the purpose of specification, is the associated test generation technique which produces a test that is guaranteed to determine correctness under certain design for test conditions. This test generation algorithm has recently b...

Generating Candidates When Testing a Deterministic Implementation against a Non-deterministic Finite-state Machine

This paper considers the problem of testing a deterministic system against a non-deterministic finite-state machine. An adaptive test process, with two phases, is proposed. The paper focuses on the first stage which involves testing to generate a candidate deterministic finite-state machine. This candidate has the property that, under the test hypotheses used, the implementation is correct if a...

Testing Non-deterministic Stream X-machine Models and P systems

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, ...

Adaptive Testing of a Deterministic Implementation Against a Nondeterministic Finite State Machine

A number of authors have looked at the problem of deriving a checking experiment from a nondeterministic finite state machine that models the required behaviour of a system. We show that these methods can be extended if it is known that the implementation is equivalent to some (unknown) deterministic finite state machine. When testing a deterministic implementation, the test output provides inf...
