android里面使用Junit具体方法：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.zj.activity"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<application android:icon="@drawable/icon" android:label="@string/app_name">
<uses-library android:name="android.test.runner" />
<activity android:name=".NetActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<!-- android:targetPackage必须与上面声明的package相同 -->
<instrumentation android:name="android.test.InstrumentationTestRunner"
android:targetPackage="com.zj.activity"/>
</manifest> OK搞定，就这么简单
