Design for Testability of Protocols Based on Formal Specifications

초록

In this paper, we propose a generic scheme which instruments a formal protocol specification automatically to enhance the testability of the implementation. This approach is a special case of design for testability. It is cost-effective considering the entire cycle of protocol development. The advantage of automatic instrumentation is that the user need not pay special attention to testing problems in the design phase. Unlike most other techniques, our scheme also works with existing protocol specifications since it does not affect the original design. Our models address the problems of controllability and observability, and can handle both sequential and concurrent formal protocol specifications.
