Collaborative Research: SoD-TEAM: Designing Tests for Evolving Software Systems

0725190陶谢北卡罗来纳州立大学AlessandroGA Tech Research CorpSOD团队：为不断演变的软件系统设计测试软件构件在其(通常很长的)生命周期中不断演变，而维护它们是软件开发中最昂贵的活动之一。相当大比例的维护成本来自回归测试，回归测试包括软件修改后的重新测试，是维护的关键部分。以前关于回归测试的研究主要集中在这一活动的效率上，而很少强调评估和改进回归测试的有效性。该项目的目标是通过以下技术的定义来填补这一空白：(1)针对一组软件变更确定测试套件的充分性，以及(2)为设计和开发针对未充分执行的变更的测试用例提供自动化支持。为了实现这一目标，研究将执行三项主要任务：定义结合依赖和状态相关信息的技术，以生成对变化的软件的回归测试需求；定义基于静态和动态分析的技术，以开发满足所确定需求的测试用例；以及通过严格的实验和工业案例研究来评估项目中定义的技术。这项研究直接解决了这个计划的既定目标，目标是开发能够改进构建和修改软件密集型系统的过程的技术。

A considerable percentage of maintenance costs are due to regression testing, which consists of retesting the software after it is modified and is a crucial part of maintenance. Previous research on regression testing has mostly focused on the efficiency of this activity, while little emphasis has been placed on assessing and improving regression-testing effectiveness. The goal ofthis project is to fill this gap through the definition of techniques for (1) determining the adequacy of a test suite with respect to a set of software changes, and (2) providing automated support for designing and developing test cases that target inadequately-exercised changes. To achieve this goal, the research will perform three main tasks: define techniques that combine dependence- and state-related information to generate regression-test requirements for changed software; define techniques based on static and dynamic analysis for developing test cases that satisfy the identified requirements; and evaluate the techniques defined in the project through rigorous experiments and industrial case studies. This research directly addresses the stated goals of this program by targeting the development of techniques that can improve the processes ofconstructing and modifying software-intensive systems.
