Coupling-Based Analysis for Integration Testing of Object-Oriented Software

9804111本研究项目试图开发新的方法来分析和测试软件组件的集成方面，特别是面向对象的软件。随着越来越多的软件使用基于对象的设计和面向对象的语言来开发，集成组件的问题对软件的成功变得更加关键。本研究项目通过软件耦合来解决这些集成问题，软件耦合是软件组件进行通信的途径。该项目在四个相关方向上应用了耦合。(1)开发实用、有效、形式化、自动化的技术，用于测试软件集成过程中组件之间的连接。(2)扩展和提炼传统的耦合度量定义，以适应现代语言的语言特征。使用耦合来开发精确的测量，并开发基于耦合来度量复杂性的完整算法。(3)开发使用耦合的算法，以计算拟议的更改将对系统的其余部分产生多大影响。此变更影响分析用于规划、成本估算和决策。(4)最后，使用耦合来确定维护变更后需要进行的回归测试量。*

9804111 This research project attempts to develop new ways to analyze and test the integration aspects of software components, particularly for object-oriented software. As more software is developed using object-based designs and object-oriented languages, the problems of integrating the components become more crucial to the success of the software. This research project addresses these integration problems through software couplings, which are the paths through which software components communicate. The project applies coupling in four related directions. (1) Develop practical, effective, formalizable, automatable techniques for testing connections between components during software integration. (2) Extend and refine traditional coupling metric definitions to handle language features of modern languages. Use couplings to develop precise measurements, and develop complete algorithms for measuring complexity based on couplings. (3) Develop algorithms for using couplings to compute how much a proposed change will affect the rest of the system. This change impact analysis is used for planning, cost estimation, and decision making. (4) Finally, use couplings to determine the amount of regression testing that needs to be done after a maintenance change is made.***
