使用cobertura确定测试代码的覆盖率

这是某个美国大学的副教授写的关于cobertura来确定测试代码覆盖率的文章讲的很清楚，我就不偷了~直接把链接放在这里

这个是一个网友写的，可以配置IDE开发环境的

http://www.blogjava.net/xmatthew/archive/2008/11/25/242658.html

这是网友写的，个人觉得对配置很有指导意义：

build.XML

1 <?xml version="1.0" encoding="UTF-8"?>

3 <project name="cobertura.examples.basic" default="coverage" basedir=".">

4

5 <!-- 引用 build.properties文件 配置路径信息-->

11 <include name="cobertura.jar" />

12 <include name="lib/**/*.jar" />

13 </fileset>

14 </path>

16 <!-- 配置 cobatura ant 扩展任务 -->

17 <taskdef classpathref="cobertura.classpath" resource="tasks.properties"/>

70 original (uninstrumented) classes. This is important.

71 -->

72 <classpath location="${instrumented.dir}" />

73 <classpath location="${classes.dir}" />

74

76 The instrumented classes reference classes used by the

77 Cobertura runtime, so Cobertura and its dependencies

78 must be on your classpath.
