说说正常的代码吧

1）

1：java测试类

<span style="font-size:14px;">package com.medivh.app;public class Person{public String sub(String username){String sub = username.substring(3);return sub;}public int add(int a,int b){return a+b;}}</span>

2：

<span style="font-size:14px;">package com.medivh.app;import org.junit.Test;import junit.framework.Assert;import android.test.AndroidTestCase;public class PersonTest extends AndroidTestCase{@Testpublic void testSub() throws Exception{Person p = new Person();p.sub(null);}public void testAdd() throws Exception{Person p = new Person();int result = p.add(1, 4);Assert.assertEquals(result, 6);}}</span>

2）AndroidManifest.xml

<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"      package="com.medivh.app"      android:versionCode="1"      android:versionName="1.0">    <application android:icon="@drawable/ic_launcher" android:label="@string/app_name">        <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><span style="color:#FF0000;"><uses-library android:name="android.test.runner" /></span>    </application>    <uses-sdk android:minSdkVersion="8" /><span style="color:#FF0000;"><instrumentation android:name="android.test.InstrumentationTestRunner"  android:targetPackage="com.medivh.app" android:label="Tests for My App" /></span></manifest> </span>

3）测试

右键项目Run as.. Android Junit Test 就会出结果

开始的时候犯迷糊结果各种出错：

No instrumentation runner found for the launch, using android.test.InstrumentationTestRunner

First does not specify a android.test.InstrumentationTestRunner instrumentation or does not declare uses-library android.test.runner in its AndroidManifest.xml

is not configured correctly for running tests

到网上各种查，发现配置没错啊。最后才发现问题出在我居然眼睛进沙子一般修改了bin下面的AndroidManifest.xml，可能是我前面打开了这个目录，结果就随意打开了它修改了它。希望大家以后小心行事。
