Abstract

Fault localization is a critical and difficult task for software quality assurance. With the increasing of software scale, the cost of manual fault localization becomes to be higher, so that many research tasks focus on automatic fault localization. Existing methods of program spectrum based fault localization locate fault to program statements, they are time consuming in large and complex software. To solve this problem, this paper proposed a two-phase fault localization method based on program spectrum. The first phase was coarse grained localization, located fault to program modules. The second phase was fine grained localization, located fault to program statements in the suspicious modules. Finally, it obtained the recommendation list of suspicious statements to assist the developer in debugging. Experimental results show that comparing with traditional methods, this method can guarantee the effect of localization and reduce localization cost by 10.24% on average.
