【摘要】 结合Java建模语言描述了程序不变量的基本概念,以程序静态分析技术和动态分析技术为基础,讲解了程序不变量在软件质量保证中的重要作用。分别针对主要的两种不变量检测工具Daikon和Diduce,叙述了它们的主要功能以及检测不变量的基本过程。阐述了两种检测工具的共性,并在此基础上进一步分析了程序不变量检测的基本理论模型,最后分析了两种工具面临的主要问题。更多还原

【Abstract】 The concept of program invariant is described combined with java modeling language in this paper.The important role of program invariant in the software quality is showed with the technology of static analyzing and dynamical analyzing.In this paper two kinds of tools of detecting program invariant with the name Daikon and Diduce are introduced separately.The main functions of Daikon and Diduce are explicated and the invariants detecting processes are showed.The common characters of the invariants detecting tools are summarized.Based on the common features,the theory model of invariants detecting is expressed in detail.At last,the main problems of Daikon and Diduce are analyzed.更多还原
