Android自动化测试生成单元测试结果报告

使用robotium进行 Android应用进行 自动化测试，之前用TMTS框架，但收集到的 单元测试结果常常会少掉一些用例集。。穷则思变，Android的测试框架主要是通过InstrumentationTestRunner对被测应用进行控制与执行，因此可以对InstrumentationTestRunner进行扩展以完成测试结果收集，然后通过jenkins的Publish  JUnit  test result report插件得到结果报告。

1.新建一个java package，新建一个java类

源码来自开源项目：https://code.google.com/p/nbandroid-utils/

源码中生成的TEST-all.xml结果文件位于/data/data/com.example/files目录下，要导出结果文件的话，需要 手机拥有root权限，比较麻烦，因此下面修改了文件存放路径，有SD卡则文件位于SD卡的/robotium目录下
