**本例为以下**DemoDao**类进行单元测试**

**－－－－－－－－－－－－－－－－新建DemoDao.java－－－－－－－－－－－－－－**

**package **com.neter.test.dao;  
  
**import **android.util.Log;  
  
**public class **DemoDao\{   
  
     **public ****void **save()\{   
          Log.i("DemoDao", "用来测试的方法");  
     \}  
       
\}

**－－－－－－－－－－－－－－－－新建DemoDaoTest.java－－－－－－－－－－－－－－**

**package **com.neter.test.dao;  
  
**import **android.test.AndroidTestCase;  
**import **android.util.Log;  
  
  
  
**public class **DemoDaoTest **extends **AndroidTestCase \{   
  
     **public void **testSave() \{   
          **new **DemoDao().save();  
          Log.i("DemoDaoTest", "测试");  
     \}  
  
\}

**-------------------------------AndroidManifest.xml--------------------------**

<?xml version="1.0" encoding="utf-8"?>  
<manifest xmlns:android="http://schemas.android.com/apk/res/android"  
      **package**="com.neter.test.dao"  
      android:versionCode="1"  
      android:versionName="1.0">  
    <uses-sdk android:minSdkVersion="8" />  
    <application android:icon="@drawable/icon" android:label="@string/app\_name">  
        <uses-library android:name="android.test.runner"/>  
        <activity android:name=".MainActivity"  
                  android:label="@string/app\_name">  
            <intent-filter>  
                <action android:name="android.intent.action.MAIN" />  
                <category android:name="android.intent.category.LAUNCHER" />  
            </intent-filter>  
        </activity>  
    </application>  
    <instrumentation android:name="android.test.InstrumentationTestRunner" android:targetPackage="com.neter.test.dao" android:label="Testing"></instrumentation>  
</manifest>

上面配置文件中

MainActivity为android程序入口，请自已新建代码略

<uses-library android:name="android.test.runner"/>不可修改

android:name="android.test.InstrumentationTestRunner不可修改

android:label="Testing"可不写

如出现Test run failed:Unable to find instrumentation target package

是因为 android:targetPackage="com.neter.test.dao" 必须和

<manifest xmlns:android="http://schemas.android.com/apk/res/android"  
      **package**="com.neter.test.dao"  
**package**相同的包名
