iPhone: Application Testing and Core Location

Question

I'm trying to implement Application Tests as described here. So far, so good, but i fail to test, for instance, the location of the device using Core Location. I have added the appropriate Framework to the Target, and have initiated the update of location, but i have no clue of how to wait for the location to be loaded, the test suite just ends before the second thread finish. Please help me to find a way to test this sort of things.

If you're relying on CLLocationManager you can implement these two delegate methods in CLLocationManagerDelegate:

- (void)locationManager:(CLLocationManager *)manager 
    didUpdateToLocation:(CLLocation *)newLocation 
           fromLocation:(CLLocation *)oldLocation

- (void)locationManager:(CLLocationManager *)manager 
       didFailWithError:(NSError *)error

Then you set the CLLocationmanager delegate and tell it to startUpdatingLocation. If you get didUpdateLocation (with oldLocation set to nil) it means you now have a location and you can consider the test a success (make sure you turn off updating). If you get the other one there was a location-manager error.

If you're relying on MapKit and are using MKMapView's user-location update mechanism, then take a look at my response to this question and implement the observer section (observeValueForKeyPath) to be notified when the map has a location (success) or implement MKMapViewDelegate's mapViewDidFailLoadingMap to be notified if there was an error.
