A semi-automatic generator for unit testing code files based on JUnit

JUnit is the de facto standard platform for Java unit testing. When we apply JUnit to put unit testing into practice, we should write some testing files, which obey the JUnit rules. These testing files have similar structure and similar codes. If we have to test a great amount of Java source files, according to the rules of JUnit, we must write almost the same amount of testing files. That is tedious work, and would cost much time and energy. This paper presents a semi-automatic generator of unit testing code files, which are derived from given Java source code files. The generator is constructed by analyzing the structure and rules of JUnit and applying reflection technique of Java language. It can alleviate tester´s burden, and improve the efficiency and velocity of unit test.
