Open Research Challenges of Localizing Faults in Programs Using Constraints

Abstract

Automated debugging, i.e., localizing faults in programs automatically using a failing test case and the source code, is still and open research topic despite the fact that there have been many different techniques already published. In this paper we focus on constraints for debugging. Constraints cannot only be effectively used for verification and testing, but also provide a foundation for automated fault localization. We briefly discuss the basic idea of constraint based debugging and outline some of the most important challenges.
