Integrating Formal Program Verification with Testing

by Admin in Formal Verification, Certification, Open Source, Events, News, Papers and Slides – March 19, 2012

This is the paper that Yannick Moy presented at the recent ERTS 2012 conference:
Verification activities mandated for critical software are essential to achieve the required level of confidence expected in life-critical or business-critical software. They are becoming increasingly costly as, over time, they require the development and maintenance of a large body of functional and robustness tests on larger and more complex applications. Formal program verification offers a way to reduce these costs while providing stronger guarantees than testing. Addressing verification activities with formal verification is supported by upcoming standards such as do-178c for software development in avionics. In the Hi-Lite project, we pursue the integration of formal verification with testing for projects developed in C or Ada. In this paper, we discuss the conditions under which this integration is at least as strong as testing alone. We describe associated costs and benefits, using a simple banking database application as a case study. The full paper can de downloaded here.
