BWDM: Test Cases Automatic Generation Tool Based on Boundary Value Analysis with VDM++

For software development using Formal Methods, we have developed a prototype of the boundary value test case automatic generation tool BWDM. The main two topics of our tool are (1) automatically generation of test cases and (2) boundary value analysis. Our tool improves the efficiency of software testing process in using VDM++ that is one of the Formal Methods. In this research, we show the composition of our tool, application example, evaluation of the usefulness, relative research, and future issues
