Automated Test Data Generation for Testing Programs with Multi-level Stack-directed Pointers
2010
Recently, a new testing technique called concolic testing receives lots of attention. Concolic testing generates test data by combining concrete program execution and symbolic execution to achieve high test coverage. CREST is a representative open-source test tool implementing concolic testing. Currently, however, CREST only deals with integer type as input. This paper presents a new rule for automated test data generation in presence of inputs of pointer type. The rules effectively handles multi-level stack-directed pointers that are mainly used in C programs. In addition, we describe a tool named vCREST implementing the proposed rules together with the results of applying the tool to some C programs.
