A new testing method for XACML 3.0 policy based on ABAC and data flow

In this paper, the authors propose a new data flow based unit testing method. The authors involved the coverage selection approach with a decision inheritance tree, which can achieve high structural coverage to design test cases. The authors evaluate the effectiveness of the methods and conducted two sets of tests by using a series of mutation operators. The evaluation results show that the new method can reach higher mutation scores.
