KLOVER: A Symbolic Execution and Automatic Test Generation Tool for C++ Programs

摘要

We present the first symbolic execution and automatic test generation tool for C++ programs. First we describe our effort in extending an existing symbolic execution tool for C programs to handle C++ programs. We then show how we made this tool generic, efficient and usable to handle real-life industrial applications. Novel features include extended symbolic virtual machine, library optimization for C and C++, object-level execution and reasoning, interfacing with specific type of efficient solvers, and semi-automatic unit and component testing. This tool is being used to assist the validation and testing of industrial software as well as publicly available programs written using the C++ language.
