eclipse中android单元测试

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
{
	@Test
	public 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。
