程序插装在软件测试中的应用研究

摘要

程序插装是软件测试中一种重要的白盒测试技术.介绍了程序插装的基本原理,分析了程序插装的关键要素,研究了插装测试设计的主要内容.针对常用的程序结构,如线性程序、结构化程序、面向对象程序的不同特点,提出了相应的程序插装策略和测试实现方法.在插装测试实践中,根据程序测试的规模、要求等,需要综合考虑程序插装对被测程序性能、执行效率等方面产生的影响,采取优化的插装方法,提高插装测试效果.%Program instrumentation is an important white-box testing technology in software testing. The basic principle of program instrumentation is introduced, the key factors of program instrumentation are analyzed, and the main contents of instrumentation testing design are studied. Aim at the different features of common used program structures, such as linear program, structured program, object-oriented program, the corresponding program instrumentation strategy and testing methods are proposed. In the practice of instrumentation testing, according to the size and demands of program testing, it is necessary to comprehensively consider the influence that program instrumentation to the tested program' s performance and the executed efficiency, in order to use the optimized instrumentation method to improve the effect of instrumentation testing.
