Research and Improvement of Test Case Design Method for Program Logic

Abstract

Test case design is an extremely important but very complicated task for dynamic test in white-box testing. In this paper, two commonly used methods, logical covering and basic path method are analyzed in detail, in order to show the deficiencies of them in high complexity, hard to use, and error prone. By combining the advantages of them, we make some improvement to the basic path testing, where independent paths are selected one by one, whose effectiveness is checked and conditions and data for the path is collected at the same time. An example is illustrated to show the feasibility and good traceability of the new design method for practical application.
