Automated Test Cases Generation from UML Class Diagram with Genetic Operator

Software testing is an important phase that ensures the quality of the software. Where test cases are an important entity or criteria by which software is being evaluated. A test case is being generated by various approaches but by means of Modeling Languages attracts the recent researches and industrialists. This paper focus on test case generation by means of UML Class diagram. Novel method is proposed to form tree structure among class in design based on their relationships. From formed tree Genetic Two point Cross over is applied to obtain all possible new trees. Depth First Searching (DFS) algorithm is used to generate test cases from the binary tree formed. Problems in usage of certain techniques are identified. A case study that is going to uses a simple, but extensively studied program is used to illustrate our approach.
