3.? 定义test runner,以及构建UI来处理测试流程，查看测试结果等。<!--[endif]-->
MyJUnitExample.java
package com.ut.prac;import junit.framework.Test;import junit.framework.TestListener;import android.app.Activity;import android.os.Bundle;import android.test.AndroidTestRunner;import android.util.Log;import android.view.View;import android.widget.Button;import android.widget.TextView;import android.widget.Toast;public class MyJUnitExample extends Activity { static final String LOG_TAG = "junit";

String testName; int testCounter; int errorCounter; int failureCounter; TextView statusText; TextView testCounterText; TextView errorCounterText; TextView failureCounterText; public TestDisplay( displayEvent ev, String testName, int testCounter, int errorCounter, int failureCounter, TextView statusText, TextView testCounterText, TextView errorCounterText, TextView failureCounterText ) { this.ev = ev;

4.?????? 最后是xml文件<!--[endif]-->
Manifest.xml
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.ut.prac" android:versionCode="1" android:versionName="1.0"> <uses-permission android:name="android.permission.WRITE_CONTACTS" /> <uses-permission android:name="android.permission.READ_CONTACTS" /> <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="android.test.runner" /> <activity android:name=".MyJUnitExample" 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" /></manifest>

Mail.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"><Button android:id="@+id/launch_button" android:text="@string/launch_test" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/status" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="" /> <TextView android:id="@+id/testCounter" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="" /> <TextView android:id="@+id/errorCounter" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="" /> <TextView android:id="@+id/failureCounter" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="" /> </LinearLayout>
?
最后编译，执行。。。
