Android单元测试配置

1.配置AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="ly.excrcise"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
         <uses-library android:name="android.test.runner" />"<!--加这句-->
        <activity android:name=".ActivityMain"
                  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>
    <uses-sdk android:minSdkVersion="3" />
　　　　<!--加下面两句-->
	<uses-permission android:name="android.permission.RUN_INSTRUMENTATION" />"
	<instrumentation android:name="android.test.InstrumentationTestRunner" 
	android:targetPackage="ly.exercise"
	android:label="Test for my app"/>"
</manifest> 

2.编写单元测试代码：必须继承AndroidTestCase

package ly.exercise;

import junit.framework.Assert;
import android.test.AndroidTestCase;

public class AndroidTest extends AndroidTestCase {
	public void test(){
		int i=4+8;
		Assert.assertEquals(12,i);
	}
}
