家电控制器软件功能测试用例生成方法研究

Research on generation of functional test cases for controllers of household electrical appliances

控制器软件质量是影响家电产品可靠性的关键因素之一。设计了基于虚拟仪器技术的软件测试系统,以NI接口板卡和LabVIEW为平台,可以有效地完成家电控制器软件的功能测试。针对自动测试用例的生成、组织、存储等系统实现的关键问题,提出了编写测试用例和从手动测试结果中抽取测试用例这两种生成手段,并提出了测试用例分析、抽象描述和数据组织的方法,其有效性和实用性在实验室及现场使用中得到了验证。

The software quality is a key factor to reliability of the household electrical appliances, and their control software is effectively tested by the system designed, which is based on the virtual instrument technology and implemented using NI interface boards and LabVIEW. The generation, organization and storage of the test cases are important in the implementation of the test system. Two ways, generated by programming or by extraction from the results of manual tests, and the methods for analysis, abstract description and data organization of test cases are brought forward. Their validity and practicability are proven by the experimental and field application results.
