Research of Reuse Technology of Test Case Based on Function Calling Path

In the process of software testing, it requires a lot of manpower and time to design test cases. Test cases of high similarities can be modified to reduce the workload of test case design, and improve the test efficiency. A test case reuse method based on function calling path is proposed. According to the change functions and the correlation functions it determined the changed path to be tested. It selected the function calling path which has high degree of similarity with the changed path to be tested from the original function calling path set. The collection of reusable test cases were determined according to mapping relationship between function calling path and test case, and the reusable test cases were modified to cover the change paths. Experimental results have validated the effectiveness of the proposed test case reuse method, and further reduce the workload of designing test cases and regression testing costs.
