一、清单中注册

<span style="font-size:14px;"> <?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="cn.itcast.test"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" />    <application         android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <uses-library android:name="android.test.runner"/>   1        <activity            android:name="cn.itcast.test.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="cn.itcast.test" android:label="Tests for My App"/>  2，写要测试的包名</manifest></span>

二、新建一个测试类，继承AndroidTest

<span style="font-size:14px;">public class PersonserviceTest extends AndroidTestCase {public void testSave() throws Exception{PersonService service = new PersonService();service.save(null);}public void testAdd() throws Exception{PersonService service = new PersonService();int result = service.add(1,2);Object actual = null;Assert.assertEquals(3, actual);}}</span>

* *File xmlFile = new File(getContext().getFilesDir(), "itcast.xml"); 内存中创建文件
