一种嵌入式软件自动测试的脚本语言

A Scripting Language for Embedded Software Automatic Test

为了提高黑盒自动化测试的人机交互便捷性以及测试用例的可维护性,文章设计了一种基于自然语言的脚本语言,通过设计用例模型和用例描述规则,实现使用自然语言作为用例脚本的描述语言并建立脚本解析机制,将自然语言描述的测试过程转化为计算机可以识别和执行的信息;基于所建立的用例模型,采用嵌套执行用例的方法,解决了功能模块相互影响导致测试结果不确定的问题。建立了一套用于机车安全设备的自动测试系统进行验证,结果表明,该方法能满足自然语言编写的测试脚本输入以及复杂耦合关联功能的测试要求。

In order to improve the convenience of human-computer interaction and the maintainability of test cases in black-box automated testing, a script language based on natural language was proposed in this paper. By designing the use-case model and the usecase description rules, use cases can be described with natural language, and the script parsing mechanism is established to transform the test process described by natural language into information that can be understood and execute by computer. In addition, based on the established use-case model, nested execution of use cases is used to solve the problem of uncertainty of test results caused by the interaction of functional modules. This method is validated by establishing an automatic test system for safety equipment of train, which satisfies the input of test scripts written in natural language and the test of complex coupling and correlation functions.
