Application of dynamic program slicing technique in test data generation

The core and key of software testing is test data generation. In the process of generating test data automatically, if the dynamic program slicing technique is used, the efficiency of generating test data can be improved. for generating test data, The main algorithm is as follows：First, in the program, we calculate the dynamic slice of the interest point's variable, and get the current value of the interest point's variable; Then In the branch function, we use the method of minimization, and guide the adjustment of program input. Through practical examples verify that, it is feasible for us to use dynamic program slicing technique in test data generation.
