VI仿真环境下嵌入式软件测试研究与应用

Embedded software testing under VI simulation environment and its application

嵌入式软件测试与通用软件测试有相通之处,也有很大差异,嵌入式系统测试与系统软硬件平台关系密切且对测试环境、测试方法都有特殊要求。测试用例设计是软件测试的核心,决定了软件测试的最终效果。在软件测试环境能更方便地进行测试用例注入,且软件测试环境直接影响着软件测试的效率。本文论述了嵌入式软件测试技术,分析了采用UML生成测试用例的方法,论述了采用VI技术搭建仿真测试环境的原理。采用所述方法实现了某型号分系统嵌入式软件测试。

There exit similarities as well as a great difference between embedded software testing and common software testing.Embedded system testing has close relationship to system software hardware platform,and also has special requirements on test environment and test methods.Test case design is the core of software testing,which determines the effect of software testing.Software testing environment can be more easily injected for test case and directly affects the efficiency of software testing.This paper discusses embedded software testing techniques,analyzes the method to generate test case by using UML,presents the principle about adopting VI technique to construct simulation test environment.A certain embedded software system has been tested by using the methods proposed in this paper.
