Research on Determination of Overloaded Function Uniqueness for Regression Testing Oriented

Function call path testing is based on static analysis of source code. The relationship between the definitions of the overloaded function and the call points is uncertain in the static analysis, which will produce a great deal of redundant paths and increase the cost of the testing. In order to determine the paths of the actual process and get function call relation, firstly, we need to determine the uniqueness of the overloaded function. We analyze the form of the overloaded function call from several aspects, design the algorithm of DUOF(determining the uniqueness of the overloaded function), ultimately determine its unique, by analyzing the realization mechanism of overloaded functions and applying the theory of compile and object-oriented. The experiment's result shows that the result of its implementation is not only accurate but also can improve the efficiency of regression testing, efficiency of the algorithm is more significant especially when the amount of code is larger.
