Automatic Program Based Test Data Generation

To minimize the cost of the manual software testing and to increase the reliability of the testing processes, it is necessary to automate it. The automatic test data generator is an important component that automatically generates test data for a given program. The random testing can be outperformed by both concolic and search based testing. There are so many proofs to prove it. Instead of it, there is not so much work but very little to show the capability of either concolic testing or search based testing with entire real world software applications. An overview of automatic test data generation is given in this paper. The basic knowledge of concolic tool, CUTE, and a search based tool, AUSTIN is also being cover. The main aim of this paper is to get the basic concept of automated program based test data generation research. The syntax based and GUI-based data generation is not considered in this paper.
