Algorithm for generation of complex test data for interface-based regression testing of software components

This paper1 describes the Complex Object Generation (COG) algorithm, a semi-automated algorithm for generating of complex instances for Java and similar languages. The algorithm is designed for black-box testing. So, it is assumed that the tested application source code is not at the disposal. The algorithm was developed and tested as a stand-alone algorithm in our Interface Analysis Tool (InAnT), but we plan to use it to generate the parameter values of generated method invocations. The generation of the method invocations is a vital part of our interface-based regression testing of software components.
