【问题描述】：
I have written a simple Gps Service. Now I am writing a testcase for testing it. I am trying to send a mock location but the onLocation changed is not getting called in my GpsService location listener.
Here is my GpsService
/**
* returns the binder object that client of this can bind to
*/
@Override
public IBinder onBind(Intent arg0) {
return mBinder;
}
@Override
public void onCreate() {
super.onCreate();
Log.e("GpsService","StartService");
}
private class MyLocationListener implements LocationListener {
@Override
public void onLocationChanged(Location loc) {
Log.e("GpsService","Location in GpsService"+loc.toString());
if(loc.hasAccuracy() && loc.getAccuracy() <= minAccuracyMeters)
{
if(targetLocation != null)
{
float distance = loc.distanceTo(targetLocation);
Log.e("GpsService ","Location latitude +"+loc.getLatitude()+"longitude "+loc.getLongitude());
if(distance < 5.0)
Toast.makeText(getBaseContext(), "You have reached the target location", Toast.LENGTH_LONG).show();
}
}
}
public void setTargetLocation (Location _location){
targetLocation = _location;
}
/**
* Class for clients to access. Because we know this service always runs in
* the same process as its clients, we don't need to deal with IPC.
*/
public class LocalBinder extends Binder {
GpsService getService() {
return GpsService.this;
}
}
private final IBinder mBinder = new LocalBinder();
@Override
public void onDestroy() {
if(lm != null)
lm.removeUpdates(locationListener);
super.onDestroy();
}
//Setting up for test case
public void setUpProvider(String provider){
lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationListener = new MyLocationListener();
lm.requestLocationUpdates(provider,
minTimeMillis,
minDistanceMeters,
locationListener);
}
Now here is my TestCase
公共类 MockLocationTest 扩展 ServiceTestCase {
private LocationManager locationManager = null;
private static final String MOCK_GPS_PROVIDER = "MOCK_GPS_PROVIDER";
private List<String> data = new ArrayList<String>();
public MockLocationTest(Class<GpsService> serviceClass) {
super(serviceClass);
}
public MockLocationTest() {
super(GpsService.class);
}
@Override
protected void setupService() {
super.setupService();
System.out.println("Service Set Up");
Intent intent = new Intent(getContext(),GpsService.class);
startService(intent);
assertNotNull("The Service should not be null",getService());
System.out.println("Service Started");
}
@Override
protected void setUp() throws Exception {
super.setUp();
}
@MediumTest
public void testBindable() {
Intent startIntent = new Intent();
startIntent.setClass(getContext(), GpsService.class);
IBinder service = bindService(startIntent);
assertNotNull("Bound to service ",service);
getService().setUpProvider(MOCK_GPS_PROVIDER);
Location demo = new Location(MOCK_GPS_PROVIDER);
demo.setLatitude(22.579937);
demo.setLongitude(88.486805);
getService().setTargetLocation(demo);
System.out.println("Test Bindable");
}
@SmallTest
public void testMockData(){
locationManager = (LocationManager) getContext().getSystemService((Context.LOCATION_SERVICE));
locationManager.setTestProviderEnabled(MOCK_GPS_PROVIDER, true);
Location location = new Location(MOCK_GPS_PROVIDER);
location.setLatitude(22.579937);
location.setLongitude(88.486805);
location.setTime(System.currentTimeMillis());
// show debug message in log
// provide the new location
locationManager.setTestProviderLocation(MOCK_GPS_PROVIDER, location);//send mock data
}
@Override
protected void tearDown() throws Exception {
super.tearDown();
}
}
很遗憾，我在服务的 onLocationChange 回调中看不到任何日志。测试用例成功运行。 我在我的服务和 testservice 的清单中都添加了以下内容
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"/>
Can anybody help me here
我也试过把它放在一个函数中
@LargeTest 公共无效 testBindable() {
Intent startIntent = new Intent();
startIntent.setClass(getContext(), GpsService.class);
IBinder service = bindService(startIntent);
assertNotNull("Bound to service ",service);
LocationManager locationManager = (LocationManager) getContext().getSystemService(Context.LOCATION_SERVICE);
locationManager.addTestProvider(MOCK_GPS_PROVIDER, false, false,
false, false, false, false, false, 0, 5);
locationManager.setTestProviderEnabled(MOCK_GPS_PROVIDER, true);
getService().setUpProvider(MOCK_GPS_PROVIDER,locationManager);
Location demo = new Location(MOCK_GPS_PROVIDER);
demo.setLatitude(22.579937);
demo.setLongitude(88.486805);
demo.setTime(System.currentTimeMillis());
getService().setTargetLocation(demo);
Location narkeldanga = new Location(MOCK_GPS_PROVIDER);
narkeldanga.setLatitude(22.578986);
narkeldanga.setLongitude(88.470154);
narkeldanga.setTime(System.currentTimeMillis());
locationManager.setTestProviderLocation(MOCK_GPS_PROVIDER, narkeldanga);
try {
Thread.sleep(10000);
// gracefully handle Thread interruption (important!)
if(Thread.currentThread().isInterrupted())
throw new InterruptedException("");
} catch (InterruptedException e) {
}
locationManager.setTestProviderLocation(MOCK_GPS_PROVIDER, demo);
try {
Thread.sleep(10000);
// gracefully handle Thread interruption (important!)
if(Thread.currentThread().isInterrupted())
throw new InterruptedException("");
} catch (InterruptedException e) {
}
System.out.println("Test Bindable");
}
但无济于事。
