我想用 ServiceTestCase 测试我的绑定服务。测试包括绑定到 MyBindServer 和发送消息。查看日志,您可以看到调用 onBind() 时服务已启动,并且从 testAHello() 发送了一条消息,但从未调用服务器的 handleMessage()。
从日志中:
I/TestRunner( 2099): started: testAHello(com.inthinc.mybindserver.test.MyBindServerTest)
I/MyBindServerTest( 2099): setUp()
I/MyBindServer( 2099): onBind, action=com.inthinc.mybindserver.START
I/MyBindServerTest( 2099): testAHello
I/MyBindServerTest( 2099): sending SAY_HELLO
[here is where I expect to see the output from handleMessage()]
I/MyBindServerTest( 2099): tearDown()
I/TestRunner( 2099): finished:testAHello(com.inthinc.mybindserver.test.MyBindServerTest)
I/TestRunner( 2099): passed: testAHello(com.inthinc.mybindserver.test.MyBindServerTest)
这是 MyBindServer.java 的代码:
package com.inthinc.mybindserver;
import android.app.Service;
import android.content.Intent;
import android.os.Handler;
import android.os.IBinder;
import android.os.Message;
import android.os.Messenger;
import android.util.Log;
public class MyBindServer extends Service {
static final String TAG = "MyBindServer";
public static final int MSG_SAY_HELLO = 1;
final Messenger mMessenger = new Messenger(new IncomingHandler());
class IncomingHandler extends Handler {
@Override
public void handleMessage(Message msg) {
Log.i(TAG, String.format("handleMessage, what=%d", msg.what));
switch (msg.what) {
case MSG_SAY_HELLO:
Log.i(TAG, "hello");
break;
default:
super.handleMessage(msg);
}
}
}
@Override
public IBinder onBind(Intent intent) {
Log.i(TAG, String.format("onBind, action=%s", intent.getAction()));
return mMessenger.getBinder();
}
}
这是 MyBindServerTest.java 的代码:
package com.inthinc.mybindserver.test;
import com.inthinc.mybindserver.MyBindServer;
import android.content.Intent;
import android.os.IBinder;
import android.os.Message;
import android.os.Messenger;
import android.os.RemoteException;
import android.test.ServiceTestCase;
import android.test.suitebuilder.annotation.SmallTest;
import android.util.Log;
public class MyBindServerTest extends ServiceTestCase<MyBindServer> {
private static final String TAG = "MyBindServerTest";
Messenger mServer = null;
public MyBindServerTest() {
super(MyBindServer.class);
}
public MyBindServerTest(Class<MyBindServer> serviceClass) {
super(serviceClass);
}
@Override
public void setUp() {
try {
super.setUp();
Log.i(TAG, "setUp()");
Intent bindIntent = new Intent("com.inthinc.mybindserver.START");
IBinder binder = bindService(bindIntent);
assertNotNull(binder);
mServer = new Messenger(binder);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void tearDown() {
try {
super.tearDown();
Log.i(TAG, "tearDown()");
} catch (Exception e) {
e.printStackTrace();
}
}
@SmallTest
public void testAHello() {
Log.i(TAG, "testAHello");
assertNotNull(mServer);
Message msg = Message.obtain(null, MyBindServer.MSG_SAY_HELLO);
Log.i(TAG, "sending SAY_HELLO");
try {
mServer.send(msg);
} catch (RemoteException e) {
e.printStackTrace();
}
}
}
