篇首语：不患人之不己知，患不知人也。本文由小常识网(cha138.com)小编为大家整理，主要介绍了知识大全 Ant+JUnit+Cobertura相关的知识，希望对你有一定的参考价值。

Java应用利器组合：Ant+JUnit+Cobertura 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　看标题就知道这个是开发一个Java应用的利器组合使用Ant完成工程的构建（Build）使用JUnit完成单元测试使用Cobertura完成代码覆蓋测试也可以辅助查找性能瓶颈和一些类型的BUG 下面是一个完整的build xml范例可以完全拿来用不需任何修改只要你的目录和这里的目录一致（应该也是很通用的）

　　下载下面的build xml文件
