摘要：Component-based software engineering, software systems are mainly constructed based on reusable components, such as third-party components and built-in components. From this approach, system quality depends on the quality of the involved components. Any change in the component, it must be changes at the unit level. Unit testing is a common step in software development. There is variety of unit testing tools available today. The main purpose is to use of a variety of automatic unit test generation tools, so that they could produce and execute large no of test inputs that are under test. In this paper, we implemented a java calculator program on the Net beans platform and test its main components under JUnit 4 testing tool. Because Net Beans platform has Inbuilt support for JUnit4 framework. It helps in reducing the cost and times of the software under test. JUnit4 testing tools help in creating robust and reliable software's. This paper also reports this tool and its features.
