Android, testing service from the test case!

Hello everybody,

This sample is specially created for Shivang Seth from Robotium conference and I would like to describe how to bind service from the test case! :)

First of all you will need:
1) Bind/unbind methods for service for setUp() and tearDown() methods accordingly;
2) Connection class to bind the service;
3) Binder implementation inside the service, should have public method 'getService' otherwise you will be not able to get the service outside the package:

public class MyServiceBinder extends Binder {

public MyService getService() {
return MyService.this;
}
}

Test case snippet:

package com.testforrobotium.mobileservice;

import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.IBinder;
import android.test.ActivityInstrumentationTestCase2;
import com.testforrobotium.mobile.tabs.MyService;
import com.testforrobotium.mobileutil.LoggerUtil;

public class MainTabActivityTest extends ActivityInstrumentationTestCase2 {

protected static String TAG = MainTabActivityTest.class.getName();

public MainTabActivityTest() {
super("com.testforrobotium.mobileservice", MainTabActivity.class);
}

public void setUp() throws Exception {
bindMyService();
}
private MyService mMyServiceBinder;
private boolean mIsServiceBound = false;

private ServiceConnection mConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
LoggerUtil.d("onServiceConnected");
mMyServiceBinder = ((MyService.MyServiceBinder) iBinder).getService();
LoggerUtil.d("Is binder == null? " + (mMyServiceBinder == null));
mIsServiceBound = true;
}

@Override
public void onServiceDisconnected(ComponentName componentName) {
LoggerUtil.d("onServiceDisconnected");
mMyServiceBinder = null;
mIsServiceBound = false;
}
};

private void bindMyService() {
Intent bindIntent = new Intent(getActivity(), MyService.class);

getActivity().bindService(bindIntent, mConnection, Context.BIND_AUTO_CREATE);

if(mMyServiceBinder != null)
mMyServiceBinder.sayHelloInLog();
else // service binder is null at this point, is not instantiated yet
LoggerUtil.d("Is binder == null? " + (mMyServiceBinder == null));
}

private void unbindMyService() {
if(mIsServiceBound) {
getActivity().unbindService(mConnection);
LoggerUtil.d("Unbinding service");
mIsServiceBound = false;
}
}

public void testMobileActivity() throws Exception {
Thread.sleep(15100);
Intent startIntent = new Intent(getActivity(), MyService.class);
startIntent.putExtra("cmd", "start");
getActivity().startService(startIntent);

Thread.sleep(5100);

mMyServiceBinder.sayHelloTestInLog();

Thread.sleep(5100);

Intent stopIntent = new Intent(getActivity(), MyService.class);
stopIntent.putExtra("cmd", "stopall");
getActivity().startService(stopIntent);
Thread.sleep(5100);

}
@Override
public void tearDown() throws Exception {
unbindMyService();
super.tearDown();
}
}

Happy testing! (:

Best regards,
