Generation of Reliability Test Data with UML for RealTime Embedded Software
-
摘要: 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.Abstract: Real-time embedded software, such as the navigation and the flight control syst ems, requires large amount of testing to measure their reliability according to the ultra-high reliability requirement. A united model language(UML)-based rel iabilit y test data generation method for real-time embedded software was presented, wh ich consists of use-case profile, interface model and test data model. The so ftware functions tested was analyzed by a use-case frofile; The interface of em bedded software was described by an interface model; The sof tware 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 b y random sampling. With this method, the tool for software reliability test data generation can be developed and this method is of practical value in soft ware reliability testing.
