"The RELAY Model of Error Detection and its Application,"
by Debra J. Richardson and Margaret. C. Thompson in
Proceeding of the Second Workshop on Testing, Verification and Analysis,
Banff Canada, July 1986.
RELAY, a model for error detection, defines revealing conditions that
guarantee that a fault originates an error during execution and that the
error transfers through computations and data flow until it is revealed.
This model of error detection provides a fault-based criterion for test
data selection. The model is applied by choosing a fault classification,
instantiating the conditions for the classes of faults, and applying them
to the program being tested. Such an application guarantees the detection
of errors caused by any fault of the chosen classes. As a formal model of
error detection, RELAY provides the basis for an automated testing tool.
This paper presents the concepts behind RELAY, describes why it is better
than other fault-based testing criteria, and discusses how RELAY could
be used as the foundation for a testing system.
