Design-for-Testability Advisor for Automated Code Generation Systems

The proposed innovation is a CASE tool advisor that will enable NASA to automatically produce higher testability code; this will allow NASA to assess their software systems to higher levels of reliability with fewer test cases. The objectives of this study are to determine how testable current CASE generated code is, decide where a testability advisor might reside, and determine the feasibility of developing a testability advisor. These objectives will be met through a feasibility study to examine the issues associated with design for testability, analysis of CASE code, and research into implementation issues. The anticipated result is a clear understanding as to how a software testability advisor can be built for a CASE environment. RST expects that the developed testability system will provide NASA with a means of developing critical software using CASE that is testable. Such an innovation will assist in the development of both aerospace and avionic systems. The developed software testability advisor will be commercialized by RST and sold along with our other testability products.
