Software systems evolve over time in order to adapt to changes inenvironment. Graceful software evolution requires that only expectedchanges in functionality occur; while desirable, this is difficult toachieve. Software tools are needed to automate the evolution ofcomplex software systems containing heterogeneous components, byreporting change impact information to programmers, allowingexamination of the effects of code edits. Tool support for changeimpact analysis has a clear potential to boost programmer productivityand enable safe code enhancement.This research in change impact analysis assumes that anobject-oriented system is developed with a suite of tests, run as thesystem is updated to check the safety of changes. Analyses candetermine which tests are affected and which changes affect each ofthese tests. Since these tests often exercise independentfunctionalities, the tests affected correspond to thosefunctionalities that may have been altered. This research will developan interactive tool for change impact analysis of Java, as part of aindustrial-strength programming environment to ensure practicality.The tool will allow experimentation with the granularity of changesand program representations, incrementalization of the analyses,collection of a Java benchmark suite, and application to collaborativesoftware development.

软件系统随着时间的推移而发展，以适应环境的变化。 优雅的软件演化要求只发生预期的功能性变化;虽然令人满意，但这很难实现。需要软件工具来自动化包含异构组件的复杂软件系统的演化，通过向程序员报告更改影响信息，允许检查代码编辑的影响。 对变更影响分析的工具支持具有明显的潜力，可以提高程序员的生产力，并使安全的代码增强。变更影响分析的这项研究假设一个面向对象的系统是用一套测试开发的，当软件更新时运行，以检查变更的安全性。 分析可以确定哪些测试受到影响，以及哪些更改会影响这些测试。 由于这些测试通常执行独立的功能，因此受影响的测试对应于可能已被更改的那些功能。本研究将开发一个交互式的Java变化影响分析工具，作为工业级编程环境的一部分，以确保实用性。该工具将允许实验的变化和程序表示的粒度，增量的分析，收集一个Java基准套件，并应用于协作软件开发。
