测试用例集扩充问题(Test Suite Augmentation)是回归测试研究的一个最新研究热点。在完成代码修改影响分析后,对已有测试用例集的充分性进行评估,若不充分则设计新的测试用例,以确保对代码修改的充分测试。但到目前为止,国内外学者并未对该研究问题的已有研究成果进行系统总结和展望。首先介绍了测试用例集扩充问题的研究背景和问题描述,然后总结出研究框架并对已有研究工作进行分类和系统比较,接着对常用评测数据集和评测指标进行了分析,最后对该问题值得关注的未来研究方向进行展望。
Test suite augmentation is a hot research issue in regression testing. After code change impact analysis,we e- valuated the adequacy of existing test suite. If not adequate, we will design new test cases to adequately test the code change. Until now, no researchers have given a survey for this research topic. We firstly introduced the research back- ground and problem description of this topic. Secondly we summarized a framework of this topic and made a systematic classification and comparison for existing research work. Thirdly we introduced the common used experiment subjects and evaluation metrics. Lastly we gave some suggestion on potential future work for this research area.
