Rigorous Vertical Software System Testing In IDE

As the size of software is getting huge, a cost for development is also increasing in a test stage as well as a development stage. To reduce the increasing cost, we need various engineering approaches in every development stage of software development life cycle. This paper researches a vertical test method which connects a system test level and a integration test level in a test stage by using UML. We study traceability between system test cases, integration test cases, and source code and a method to curtail expenses during communications between developers and test engineers.
