嵌入式软件可测试性度量及评估技术研究

Research on metric and evaluation technology of embedded software testability

软件的可测试性的程度直接影响软件测试的质量、效率和充分性,进而影响软件的质量和可靠性。目前,嵌入式软件缺乏可测试性度量和评估的相关技术研究,无法为嵌入式软件可测试性的需求设计和过程改进提供依据。因此,文章首先从软件可测试性定义、应具备的特征出发,根据嵌入式软件的特点,提出一种嵌入式软件的可测试性度量模型和评估方法,并给出嵌入式软件可测试性评估的一个实例。

Software testability has directly effect on the quality,the efficiency and the adequacy of software testing,which affects the quality and reliability of software at the same time. Now research on metric and evaluation technology of embedded software testability is absence,which can not support software testability requirement,software testability design and process improvement. This paper firstly described the defination and characteristics of software testability,according to characteristic of embedded software,put forward a method of metric and evaluation on embedded software testability and presented an example of one embedded software testability metric and evaluation.
