结合需求与反馈的动态测试用例优先级排序方法

摘要

In order to improve the defect detection rate in the process of software testing dynamic test case prioritization using combination of requirements and feedback is proposed in this paper. First initialize the test case priority according to the requirement priorities and require⁃ment change and then adaptivly adjust the unexecuted test cases prioritization according to requir⁃ement relativity and feedback in the following execution until the test case execution conditions out of date. The results of being validated in the project GPSking are followings the APFD is 68�73% using the dynamic method the APFD is 51�4% using created time and the APFD is 67�5% using the static method. The experimental result shows that this method can improve the defect rate.%为提高软件测试的缺陷检测速率，提出结合需求与反馈信息的动态测试用例优先级排序方法。根据需求优先级和需求是否变更对测试用例优先级进行初始化，执行过程中结合需求相关性和反馈信息动态调整未被执行的测试用例的优先级，直到测试用例执行条件跳出为止。在GPSking中的验证结果为：本方法的APFD为68�73％，而测试用例按被创建顺序的APFD为51�4％，仅采用需求优先级静态排序的APFD为67�5％。结果表明，该方法能很好地提高缺陷检测速率。
