摘　　要：测试需求优先级排序是提高测试资源使用效率的有效手段之一。为解决当前测试需求分析过程中优先级度量较随意的问题,本文提出将风险模式、影响及危害性分析(Risk Mode and Effects Criticality Analysis,RMECA)应用于测试需求优先级排序的方法。该方法从软件需求失效的发生、发现和实现角度提取风险因子,通过分配权值,可定量设置每个测试需求的优先级,从而得到一个可信的测试需求优先级序列。文中给出了一个采用基于RMECA的测试需求优先级计算实例。Test requirement prioritization is an effective and validity technique of improving on the usage of test resource.To solve the random of metrics for test requirement essentiality,a test requirement prioritization algorithm based on RMECA is proposed in this paper,which obtains risk factors from the happening、exposure and realization when the requirement is broken,then the quantificational priority of test requriement is achieved by evaluates every factor and adjusts its weight.An example of prioritization based on RMECA is presented finally.
