1.进行单元测试前，需要在manifest文件中添加测试的权限以及使用的测试类

配置文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.zizhu.junit"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="10" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".JunitTestActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <uses-library android:name="android.test.runner" />
    </application>

    <uses-permission android:name="android.permission.RUN_INSTRUMENTATION" />
    
    <instrumentation
        android:name="android.test.InstrumentationTestRunner"
        android:label="junit test my app"
        android:targetPackage="com.zizhu.junit" />

</manifest>

2.继承自AndroidTestCase即可进行测试

package com.zizhu.test;

import junit.framework.Assert;

import com.zizhu.service.PersonService;

import android.test.AndroidTestCase;

public class PersonServiceTest extends AndroidTestCase {
	
	public void testSave(){
		PersonService ps = new PersonService();
		ps.save("zizhu");
	}
	
	public void testAdd(){
		PersonService ps = new PersonService();
		Assert.assertEquals(33, ps.add(11, 22));
	}
	
}
