本文介绍如何使用junit-report包配置Android工程，以生成JUnit格式的测试报告。包括添加依赖、修改配置文件、运行测试及获取报告的具体步骤。

junit-report包下载地址：https://github.com/jsankey/android-junit-report/downloads

1、添加测试包到被测工程的lib下，Build Path---Add to Build Path

2、修改android的AndroidManifest文件，将

<instrumentation
android:name="android.test.InstrumentationTestRunner"

修改为

<instrumentation
android:name="com.zutubi.android.junitreport.JUnitReportTestRunner"

3、修改执行参数右键工程：Run As---Run Configurations

下拉选择修改为com.zutubi.android.junitreport.JUnitReportTestRunner

4、1运行Android JUnit Test，跑完测试用例后会在被测工程的文件夹下的files文件夹中生成junit-report.xml文件（/data/data/被测包名/files/junit-report.xml）

4、2如果不使用Android JUnit Test，则按如下方式运行，注意修改

adb shell am instrument -e class com.netease.mobile.autotest.testing.LoginTest#testLogin -w com.netease.mobile.autotest/com.zutubi.android.junitreport.JUnitReportTestRunner

adb shell am instrument -e class com.netease.mobile.autotest.testing.LoginTest#testUnLogin -w com.netease.mobile.autotest/com.zutubi.android.junitreport.JUnitReportTestRunner

5、adb pull /data/data/(your app package name)/files/junit-report.xml e:/

如果要修改结果保存地址，需要重写类InstrumentationTestRunner

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.
