Android下使用JUnit

二、配置\layout\main.xml文件，加入两个button组件，代码如下：

<?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:text="Button01" android:id="@+id/Button01"
  android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
 <Button android:text="Button02" android:id="@+id/Button02"
  android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>

 三、被测试的Activity代码

package cc.androidos.activity;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
public class NewActivity extends Activity {
    /** Called when the activity is first created. */ 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
    public int add(int a , int b){
     return a+b;
    }
}

 四、测试NewActivity代码，这里要继承ActivityInstrumentationTestCase2，ActivityInstrumentationTestCase2是TestCase的子类

package cc.andoridos.activity.test;
import cc.androidos.activity.NewActivity;
import cc.androidos.activity.R;
import android.test.ActivityInstrumentationTestCase2;
import android.util.Log;
import android.view.KeyEvent;
import android.widget.Button;
public class TestNewActivity extends
  ActivityInstrumentationTestCase2<NewActivity> {
 private Button button1 = null;
 private Button button2 = null;
 private NewActivity newActivity = null;
 public TestNewActivity() {
  super("cc.androidos.activity", NewActivity.class);
  //This first parameter should the Activity package
  //if other , the junit give us the exception: unable resolve the activity
 }
 
 @Override
 protected void setUp() throws Exception {
  String tag = "setUp";
  Log.e(tag, "init all var....");
  newActivity = getActivity();
  button1 = (Button) newActivity.findViewById(R.id.Button01);
  button2 = (Button) newActivity.findViewById(R.id.Button02);
 }
 /**
  * Testing the button is focused or not
  */
 public  void testButtonFocus() {
  String tag = "testButtonFocus";
  Log.e(tag, "start the button focus...");
  assertTrue("Button1 is focused", button1.isFocused());
  Log.e(tag, "send the down key event...");
  sendKeys(KeyEvent.KEYCODE_DPAD_DOWN);
  assertTrue("Button2 is focused", button2.isFocused());
 }
 
 /**
  * Testing the add method in actvity
  */
 public void testAdd(){
  String tag ="testAdd";
  Log.e(tag, "Test the add method in NewActivity...");
  int i  = newActivity.add(2, 5);
  assertEquals(7, i);
 }

 
}

 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="cc.androidos.activity" android:versionCode="1"
 android:versionName="1.0">
 <application android:icon="@drawable/icon" android:label="@string/app_name">
  <activity android:name=".NewActivity" android:label="@string/app_name">
   <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
   </intent-filter>
  </activity>
  <activity android:name=".NewActivity2" android:label="@string/app_name">
  </activity>
  <uses-library android:name="android.test.runner" />
  <!-- Loading test library -->
 </application>
 <uses-sdk android:minSdkVersion="3" />
 
<!--这个是关键，android:targetPackage="cc.androidos.activity"要测试的包，android:name="android.test.InstrumentationTestRunner" 用于跑TestCase的类-->
 <instrumentation android:targetPackage="cc.androidos.activity"
  android:label="Test New Activty" android:name="android.test.InstrumentationTestRunner"></instrumentation>
</manifest> 

六、运行模拟器和项目

 

 七、在TestCase类中点击右键：

九、不使用Eclipse，控制台的命令：

E:\android\android-sdk-windows-1.5_pre\tools>adb shell am instrument -w cc.andro
idos.activity/android.test.InstrumentationTestRunner

如果你配置了Android环境变量，直接使用：
adb shell am instrument -w cc.androidos.activity/android.test.InstrumentationTestRunner
语法：adb shell am instrument -w <被测试的类的包名>/android.test.InstrumentationTestRunner
参数参考帮助文档
