Abstract

A character string is an important element inprogramming. A problem that needs further research ishow to automatically generate software test data forcharacter strings. This paper presents a novel approachfor automatic test data generation of program pathsincluding character string predicates, and the effectivenessof this approach is examined on a number of programs.Each element of input variable of a character string isdetermined by using the gradient descent technique toperform function minimization so that the test data ofcharacter string can be dynamically generated. Theexperimental results illustrate that this approach iseffective.
