android对应用进行单元测试

1.新建一个android工程

?2.创建两个包，一个service包，用来存放业务逻辑类，一个test包，用来存放我们 ? ? ? ? 写的单元测试类

?3.编写一个业务逻辑类

?

package com.xiaobo.app.service;public class PersonService {public String subString(String str) throws Exception{return str!=null ? str.substring(6) : "";}public int getSum(int a, int b) throws Exception{return a+b;}}

?

?4.编写测试用例

?

package com.xiaobo.app.junittest;import junit.framework.Assert;import com.xiaobo.app.service.PersonService;import android.test.AndroidTestCase;public class PersonServiceTest extends AndroidTestCase{PersonService personService = new PersonService();public void testSubString() throws Exception{String subStr = personService.subString(null);assertNotNull(subStr);}public void testGetSum() throws Exception{Assert.assertEquals(3, personService.getSum(1, 2));}}

?
?5.在AndroidManifest.xml进行配置

?

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.xiaobo.app.junittest"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="1"        android:targetSdkVersion="17" />    <uses-permission android:name="android.permission.RUN_INSTRUMENTATION" /> <instrumentation android:name="android.test.InstrumentationTestRunner"      android:targetPackage="com.xiaobo.app.junittest"  android:label="JUnit Test"/>         <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <!-- 但如单元测试的library -->        <uses-library android:name="android.test.runner" />         <activity            android:name="com.xiaobo.app.junittest.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></manifest>
