电子电器产品嵌入式软件单元测试技术研究

Research on Embedded Software Unit Testing for Electrical and Electronic Products

电子电器产品中嵌入式软件的故障和失效已是产品质量出现问题的重要原因之一,软件测试是保证软件质量的重要手段,单元测试作为软件测试过程的第一阶段,高质量的测试效果是确保整个测试的必要条件。通过对典型嵌入式软件测试工具RTRT(Rational Test RealTime)的分析及利用RTRT进行实际电器产品软件单元测试的试验,结果表明RTRT是一个可以有效得应用于电子电器产品嵌入式软件开发和测试阶段的自动化测试工具,利用RTRT进行软件单元测试可以减少测试工作量,加快测试进度和提高软件测试质量。

Unit testing as the first stage of the software testing process,its testing quality is necessary condition for ensuring the entire test results.Through analysising on RTRT （Rational Test RealTime） wl^ich is the typical embedded software testing tool and teting on the actual electrical products with RTRT, it shows that RTRT can effectively be applied to embedded software development and testing phases of electrical and electronic products.Software unit testing by RTRT can reduce tc^tinn offnrt enoch l ln tho nrt^r~ r^f thc~ t^t ~nH imnrn^lo c^t~f^Al^r~ t^aetinr~ r^lit~
