构件软件回归测试用例选择策略

软构件技术虽被广泛应用于软件系统的开发中，但其测试问题并未得到很好地解决．系统构建者对外部提供的构件内部结构及其变更信息缺乏了解，很难选择出与构件变更相关的用例用于下一轮的测试．分析已有回归测试技术的不足，提出了两种改进的回归测试策略：一种是基于增强的构件版本变更信息的方法；另一种则是基于内建式测试设计的方法．通过对几个实例程序的实验分析，初步证实了所提出的方法在实际应用中的可行性与有效性．

Strategies of Regression Test Case Selection for Component-Based Software

Component-based software technology has been increasingly adopted in the development of large-scale and complex software systems. However,the testing problem induced by it hasn't been settled perfectly and is still one of the open issues in component-based software engineering (CBSE). Due to the lack of information about the constructs and changes in externally-provided components,system testers (i.e.,component users) generally can't perform effective regression testing on their component-based software systems (CBSs). The ultimate reason is that they aren't able to select the proper test cases to retest the modification caused by the changes in component. Through analyzing the drawbacks of the existing regression testing techniques for CBSs,two improved strategies are proposed. One is based on the enhanced representation of change information of component version,and the other is implemented via the component built-in test design. Preliminary experiments have been employed on some medium scale systems,and experiment results show that the strategies of regression test case selection are feasible and effective in practice.
