摘　　要：冗余通道设计是反应堆安全级仪控系统提高可靠性的一种常用技术手段。在安全级仪控系统测试工作中,测试阶段通常面临着交货节点的压力,会导致测试时间十分紧迫。为提升测试效率,提出了一种测试执行优化方案,建立了以异常检测率、严重异常检测能力和代码覆盖率为影响因素的优先级计算方法,根据不同测试目标调整各影响因素权重。以缺陷检测加权百分比(APFD)这一测试指标定量描述测试执行效果,验证了测试用例优先级方法的有效性。所述方案在回归测试以及仪控系统冗余通道测试中具有良好的应用前景。Redundant channel design is a commonly used technical means to improve the reliability of reactor safety level instrument and control system.In the testing of safety level instrument and control systems,the test testing phase usually faces pressure from delivery nodes,which can lead to very tight testing time.To improve testing efficiency,this paper proposes a testing execution optimization scheme,which establishes a priority calculation method based on anomaly detection rate,severe anomaly detection ability,and code coverage as influencing factors.According to different testing objectives,it can change the weights of each factor.The effectiveness of the test case prioritization method was validated by quantitatively describing the test execution effect using the defect detection weighted percentage(APFD)as a testing indicator.
