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
package com.example.test.instrumentation;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.Writer;
import org.xmlpull.v1.XmlPullParserFactory;
import org.xmlpull.v1.XmlSerializer;
import android.content.Context;
import android.os.Bundle;
import android.os.Environment;
/**
* This test runner creates a TEST-all.xml in the files directory of the application under test. The output is compatible with that of the junitreport ant task， the format
* that is understood by Hudson. Currently this implementation does not implement the all aspects of the junitreport format， but enough for Hudson to parse the test results.
