Test Case Priority Technology for Nuclear Instrumentation and Control Systems
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 pro-poses 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.
