碩士 === 銘傳大學 === 資訊管理學系碩士班 === 107 === When developing a large software system, debugging is a very time-consuming process. As a result, Automatic Program Debug and Repair has become a hot research topic. In this thesis, we first review the Nopol system that can debug and repair Java programs, based on both the Test-Based Debug and Repair Model and the Single-Fault Model. Second, we revise Nopol to debug and repair JavaScript programs that are now popular in designing the front-end interface of web systems. Though Java and JavaScript share a lot of aspects, we point out that the latter one involves a lot of function calls that would cause a single-fault to become multiple faults that could not be debugged by the mechanism of Nopol. In addition, we propose a new mechanism to overcome this problem. Finally, we replace the brute-force patch generation process of Nopol with a new process that produces patches based on the special characteristics of JavaScript programs.
