【摘要】 如何从UML模型生成测试用例为面向对象软件测试带来了新的挑战。为测试用例提供测试数据是其中的关键环节。Shaukat Ali等人在UML基础上提出SCOTEM模型,但是此模型的测试数据需要人工生成。针对SCOTEM模型进行了改进使其适于灰盒测试,以OCL约束测试数据的生成和运行结果的验证,并提出了一种为基于粒子群算法的改进SCOTEM模型自动生成测试数据的方法。针对不同的覆盖标准,实验证明该方法能够以更高的效率生成高质量的测试数据。更多还原

【Abstract】 Generation of test cases bring challenges to OO software test.And providing test data for test cases is a key point.Shaukat Ali present a UML-based model called SCOTEM.But test data needs to be generated manually.An improvement is made to SCOTEM to adapt to grey-box testing.OCL is used to constrain test data generation and test result validation,and an approach is proposes to generate test data for the enhanced SCOTEM based on particle swarm optimization algorithm.The experimental results show that it can generate higher quality test data more efficiently under different coverage criterion.更多还原
