Verifying Consistency and Validity of Formal Specifications by Testing

چکیده
Detecting faults in specications can help reduce the cost and risk of software development because incorrect implementation can be prevented early. This goal can be achieved by verifying the consistency and validity of specications. In this paper we put forward specication testing as a practical technique for verication and validation of formal specications. Our approach is to derive proof obligations from a specication and then test them, in order to detect faults leading to the violation of consistency or validity of the specication. We describe proof obligations for various consistency properties of a specication, and suggest the use of ve strategies for testing them. We provide a method for testing implicit specications by evaluation rather than by prototyping, and criteria for interpreting the meaning of test results.

A Non-interleaving Timed Process Algebra and a Process Logic for Verifying Composition of Agents
We present formal frameworks tCCA, tLCA, and tICCA for verifying composition of agents. Behaviors of composite agents are described in tCCA and specifications for them are described in tLCA. Since consistency between specifications in tLCA is undecidable as proven in this paper, we propose to use intermediate specifications described in tICCA instead of directly checking the consistency, and th...

متن کاملVerifying Formal Specifications Using Fault Tree Analysis∗
Specification before implementation has been suggested as a sensible approach to software evolution. The quality of this approach may be improved by using formal specification. However, to serve as a trustable foundation for implementation and to help reduce the cost in program testing, the formal specification must be ensured to be satisfiable, consistent, complete, and accurate in recording t...
