基于TestQuest的嵌入式软件可靠性测试环境框架研究

嵌入式软件是软件中最难测试的一种软件,该文提出了一种嵌入式软件可靠性测试环境框架,分析了嵌入式软件测试与普通软件测试的异同。针对嵌入式软件难于测试的问题,运用仿真测试和自动化测试方法,并利用TestQuest工具辅助构建环境,重点介绍了框架中各个模块的功能、实时控制器的分层结构实现、上位机与实时控制器的通信协议编写方法,最后通过实例验证该平台有良好的适应性和易操作性。

Framework of reliability test environment for embedded software based on TestQuest

The embedded software is difficult to test.The paper proposes a framework of reliability test environment for it.Firstly,it analyzes the difference and similarity between the embedded software test and common software test,and introduces the establishment of test environment with commercial software TestQuest according to the theory of stimulation testing and automation testing.Secondly,it illustrates the function of each component in the framework,the realization of hierarchical structure of real-time controller,and the compiling method of communication protocol between host computer and real-time computer.The framework extends the application area of the test environment,with good adaptability and operationability.
