UML在软件可靠性测试数据自动生成中的运用

为了自动生成实时嵌入式软件的可靠性测试数据,利用UML(统一建模语言)提供的建模机 制,从软件可靠性测试的角度建立use-case剖面、接口模型和测试数据实现模型,然后根 据 这些模型的描述进行随机抽样,自动生成可靠性测试数据.利用该方法能够开发出相应的测 试数据自动生成工具,在软件可靠性测试领域有着较大的实用价值.

Generation of Reliability Test Data with UML for Real-Time Embedded Software

Real-time embedded software, such as the navigation and the flight control systems, requires large amount of testing to measure their reliability according to the ultra-high reliability requirement. A united model language(UML)-based reliability test data generation method for real-time embedded software was presented, which consists of use-case profile, interface model and test data model. The software functions tested was analyzed by a use-case frofile; The interface of embedded software was described by an interface model; The software operational profile was depicted by a test data model. Based on the three models, the reliability test data for the real-time embedded software can be generated by random sampling. With this method, the tool for software reliability test data generation can be developed and this method is of practical value in software reliability testing.
