Abstract

. Structural testing techniques are widely used in the unit testing process of softwares. A major challenge of this process consists in generating automatically test data, i.e., in nding input values for which a selected point in a procedure is executed. We introduce here an original framework where the later problem is transformed into a CLP(FD) problem. Specic operators have been introduced to tackle this kind of application. The resolution of the constraint system is based upon entailment techniques. A prototype system | named InKA| which allows to handle a non-trivial subset of programs written in C has been developed. First experimental results show that InKa is competitive with traditional ad{hoc methods. Moreover, InKa has been used successfully to generate test data for programs extracted from a real application. 1 Introduction Structural testing techniques are widely used in the unit or module testing process. Structural testing requires : 1. Identifying a set ...
