XCTest fails with with exception 'Non-UI clients cannont be autopaused'

I am trying to test creation of CLLocationManager as a singletone with default parameters:

+ (GeolocationService *)defaultGeolocationService
{
    static GeolocationService *_defaultGeolocationService = nil;

    static dispatch_once_t oncePredicate;

    dispatch_once(&oncePredicate, ^{
        _defaultGeolocationService = [[GeolocationService alloc] init];
        [_defaultGeolocationService initLocationManager];
    });

    return _defaultGeolocationService;
}

- (void)initLocationManager
{
    self.locationManager = [CLLocationManager new];
    self.locationManager.delegate = self;
    self.locationManager.pausesLocationUpdatesAutomatically = YES;
    [self.locationManager requestAlwaysAuthorization];
}

Test looks like this:

- (void)testInitWithDefaultsSettings
{
    GeolocationService *defaultGeolocationService = [GeolocationService defaultGeolocationService];

    XCTAssertTrue(defaultGeolocationService.settings.autoPause, @"autoPause");
}

And I get an exception: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Non-UI clients cannont be auto paused'

What should I do to make this test work?
