基于信息流缺陷定位方法在软件测试中的应用

随着软件产业的飞速发展,人们对软件质量的要求也越来越高.现在,软件已经直接影响到了我们项目的成功和设备的安全.而软件中的复杂缺陷难以排除,因为它们涉及到许多程序要素之间的相互作用.论文扩展了基于信息流覆盖的缺陷定位技术.扩展后的技术融合了语句覆盖和分支覆盖技术,它还能定位复杂缺陷.试验结果表明,文中方法比基于语句覆盖、分支覆盖和定义使用对覆盖的方法要更可靠、更精确.

Application of Defect Localization Technique in the Software Testing Based on Information Flow

With the development of the software industry,people require higher quality of software.Today,software directly impacts on the success of our project and the safe of our device.The complex defects often are hard to debug,because they involve the interactions between many program elements.This paper expands the fault localization technique,which is based on information flow coverage.The expanded technique combines the statement coverage and branch coverage technique,and it can localize the complex defect.The experiment result shows that our method is more reliable and precise than other methods,which includes statement coverage,branch coverage and define-use pair coverage.
