A SURVEY OF AUTOMATED TEST DATA GENERATION TECHNIQUES

Abstract

Software Testing is most labour intensive task and accounts for fifty percent of total cost of development. To
reduce high cost of manual testing researchers have tried to automate the software testing process. Test data generation
for a given program is the most important problem to be solved in the automated testing process. Many researchers are
actively showing the interest in the field of automated test data generation. Many new advancements have been seen in
the field of test data generation over past few years. The focus of this paper is to elaborate and review the test data
generation techniques used for structural testing. Symbolic execution has received much attention for structural test data
generation. Though symbolic execution has many other applications our focus in this paper is to explore the use of
symbolic execution in test data generation. Symbolic execution has some limitations when it comes to implement the
techniques for real world application like path explore, complex constrains. We discussed the availble solutions to the
common problems with the symbolic execution.
