上游充通大 JUNIT SHANGHAI JIAO TONG UNIVERSITY For application developers,testing forms an integral part of the development life-cycle. As old code is modified for reasons ranging from adding new functionality to speed optimizations,the risk of dependent functionality getting broken Increases. Tests that are written once,and can be run repeatedly is the only solution to avoid manually QA testing. To write these tests,for applications written in java, JUnit provides a solid framework for writing unit tests.Many JUnit integrations also exist to integrate your JUnit tests into build and development tools

上游充通大学 在Eclipse中使用JUNIT SHANGHAI JIAO TONG UNIVERSITY 测试对于保证软件开发质量有着非常重要的作用， 单元测试更是必不可少，JUit是一个非常强大的 单元测试包，可以对一个/多个类的单个/多个方 法测试，还可以将不同的TestCase:组合成 TestSuit,使测试任务自动化。Eclipse同样集成 了JUnit,i 可以非常方便地编写TestCase。 我们创建一个Java工程，添加一个 example.Hello类，首先我们给Hello类添加一个 abs0方法，作用是返回绝对值：
