对象驱动的软件测试性度量

为了使用统一的方式度量各种软件的测试性,降低测试性度量的难度和费用,提出一种对象驱动的软件测试性度量方法. 方法基于一个由测试性度量、易测试特性度量、测试性因素度量及其关系构成的软件测试性度量框架,首先分析度量的对象,确定对象的类型、对象所属软件的类型和测试情况;然后根据软件的类型和测试情况,从度量框架中选取匹配的元素,构造一个专用的软件测试性度量框架;最后根据度量对象的类型,使用专用软件测试性度量框架中的元素计算测试性因素、易测试特性或测试性. 应用表明方法能够得到软件测试性的定量结果,预计测试资源,为软件测试提供帮助.

Object-driving software testability measurement

To reduce the difficulty and cost of software testability measurement, an object-driving method was proposed to measure the testability of various programs by a unified manner. It is based on a software testability metrics framework that consists of the testability metric, testable characteristics metrics, testability factors metrics and their relations. First, the measurement object was analyzed to determine the object type, the software type and test conditions. Then suited elements were chose from the metrics framework according to the software type and test conditions to construct a special software testability metrics framework. Finally advantage of the elements in the special metrics framework was taken to calculate the testability factors, testable characteristics or testability according to the object type. The application indicates this method can get the quantitative value of software testability and help the software testing by predicting the test resources.
