| 摘要: |
| 缺陷定位是软件调试过程中的重要环节,它通过利用程序信息和测试信息来定位软件中的错误.借助于事件信息量,提出一种基于事件信息量的缺陷定位方法——SIQ(suspiciousness based on information quantity).SIQ 方法根据测试信息中不同事件的类型及其发生的概率,结合语句的执行信息,动态计算和调整缺陷定位的结果.通过大量的实验分析和对比,SIQ 方法在多个数据集上表现出了很好的稳定性,与几种现有的缺陷定位方法相比,SIQ 方法的缺陷定位效果也更加准确. |

| Abstract: |
| Fault localization is an important step in debugging. It makes use of the information from the source code and testing to locate bugs in software. This paper presents a method using the information quantity of testing events, called SIQ (suspiciousness based on information quantity). SIQ adjusts the fault localization procedure dynamically according to the testing events and the execution information of statements. In a series of experiments and analysis, SIQ takes on excellent stability in multiple data sets and has better localization accuracy compared to several existing methods. |
