Unit Test CLLocationManager implementation

Question

I have a class named "GeolocationManager" that handles a CLLocationManager object and delegate responses.

- (void)getGeolocationForClient:(id<GeolocationManagerDelegate>)client
{
    _delegate = client;
    _locationManager = [self createLocationManager];
    _locationManager.delegate = self;
    _locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters;
    [_locationManager startUpdatingLocation];
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
   // do some stuff
}

createLocationManager is a public method ready to be stubbed

- (CLLocationManager *)createLocationManager
{
    return [[CLLocationManager alloc] init];
}

What I want to achieve is to test that when user denies being geolocated the CLLocationManagerDelegate method locationManager:didFailWithError: is being called on my GeolocationManager object.

My test method below does not seem to be working

- (void)testOnUserDenial
{
    GeolocationManager *geolocationManager = [[GeolocationManager alloc] init];
    id geolocationManagerTest = [OCMockObject partialMockForObject:geolocationManager];

    CLLocationManager *locationManager = [[CLLocationManager alloc] init];
    id locationManagerTest = [OCMockObject partialMockForObject:locationManager];

    [[[locationManagerTest stub] andReturnValue:@(kCLAuthorizationStatusDenied)] authorizationStatus];
    [[[geolocationManagerTest stub] andReturn:locationManagerTest] createLocationManager];

    [[geolocationManagerTest expect] locationManager:[OCMArg any] didFailWithError:[OCMArg any]];

    [geolocationManagerTest getGeolocationForClient:[OCMArg any]];

    [geolocationManagerTest verify];
}

Answer 1

Have you tried using OCMOCK_VALUE(kCLAuthorizationStatusDenied) for the returnValue?
