JUCC:一种基于JUnit框架展示代码覆盖的交互式测试工具

JUCC: an Interactive JUnit-based Testing Tool with Code Coverage

当前测试驱动的开发模式已成为软件开发的主要模式之一,而JUnit是测试开发领域中常用的一种测试框架.基于JUnit的各种测试技术和方法经常出现在各种软件测试研究与实践中.本文基于JUnit框架,提出一种添加代码覆盖展示的新型交互式测试工具JUCC.JUCC在JUnit测试结束后根据测试过程中记录的信息,图形化地显示测试代码的覆盖率,这样,测试人员可根据代码覆盖情况针对没有被覆盖的代码再次进行测试用例的编写,迭代地进行测试,直到达到满意的测试效果.

The Test-driven development （ TDD ） concept has deeply rooted in the software development life cycle. And in TDD, JUnit is one of the most famous and successful testing tools in software testing research and practice. Based on JUnit, this paper proposes a framework, JUCC, which facilitates interactive unit testing by displaying the test code coverage. JUCC can effectively collect and graphically show the test coverage information during running of the JUnit. Thus, the testers can interactively generate new test cases based on the test running information to execute the uncovered code. And this process is iteratively proceeded until it achieves some testing criteria fit to practical needs.
