how to test no location service

I am developing an application which uses location services. I know how to check if location service is available with isProviderEnabled method of LocationManager class. I checked all three services like this

    LocationManager loma=(LocationManager)context.getSystemService(Context.LOCATION_SERVICE);

    if(loma.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
        loma.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, MIN_TIME, MIN_DISTANCE, this);
        //do stuff
    }
    if(loma.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
        loma.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME, MIN_DISTANCE, this);
        //do stuff
    }
    if(loma.isProviderEnabled(LocationManager.PASSIVE_PROVIDER)) {
        loma.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER, MIN_TIME, MIN_DISTANCE, this);
        //do stuff
    }

But I do not know how test it. Even though I closed location services in my phone and genymotion everything works like location is on. Is there anyone know how to test this?
