  目:Testing Based Formal Verification for Software Quality Assurance and Cost Reduction

内容简介:Testing and formal verification are two important means for softwareverification and validation, but they suffer from critical challenges. Testingshows the presence of bugs but never their absence. Formal verification canshow the correctness for correct programs but not for incorrect programs.Unfortunately, the very reality in software development is that a newlydeveloped system always contains bugs and is unlikely to be correct in thebeginning. How to formally prove the correctness of programs in acost effective manner is still a challenge. In this talk, after briefly discussingthe characteristics and challenges of current verification and validationapproaches, a new approach, known as Testing Based Formal Verification(TBFV), will be introduced. TBFV results from an appropriate integration offormal specification based testing and Hoare logic for proving programcorrectness. It is a rigorous gray box testing approach that takes both thespecification and the program structure into account. The most importantbenefit of TBFV is that it can be applied automatically to ensure thecorrectness or high reliability of programs.
