Promise not resolving data in Jasmine test - Angular

I have a service making reverse geocoding (translate coordinates into an address), and I use a promise to get the result.

When I try to test it, it does not resolve data even if I call the digest loop on the rootscope and it returns the test is passed even if conditions can't be satisfied.

Here it is the test file

'use strict';

describe('revGeocodeService', function() {

var revGeocodeService;
var resultAdd="";


beforeEach(function() {
    module('angularApp');
});

var $rootScope;

beforeEach(inject(function(_revGeocodeService_,_$rootScope_) {
    revGeocodeService=_revGeocodeService_;
    $rootScope = _$rootScope_;
}));

it('should reverse position to an address', function() {
    var position={};
    position.latitude=51.5310315;
    position.longitude=-0.06899029999999999;


    revGeocodeService.getAddress(position).then(function(result)
                {
                    resultAdd=result;
                    expect(1).toBe('somevalue');
                });
    $rootScope.$digest();
});

});

and here it is the service

'use strict';

(function(){
var revGeocodeService= function($q){
    return{
        getAddress : function(position){
            console.log(position.latitude+" "+position.longitude);
            //set up the promise
            var deferred = $q.defer();

            // set up the Geocoder object
            var geocoder = new google.maps.Geocoder();
            // turn coordinates into an object
            var yourLocation = new google.maps.LatLng(position.latitude, position.longitude);

            // find out info about our location
            geocoder.geocode({ 'latLng': yourLocation }, function (results, status) {

            if(status == google.maps.GeocoderStatus.OK) {
              if(results[0]) {
                  console.log(results[0].formatted_address);
                  // return results[0].formatted_address;
                  console.log(results[0].formatted_address);
                  deferred.resolve(results[0].formatted_address);

              } else {
                error('Google did not return any results.');
                deferred.resolve (null);    
              }
            } else {
              error("Reverse Geocoding failed due to: " + status);
              deferred.resolve(null);   
            }


          });

            return deferred.promise;

        }
    }
}

angular.module('angularApp').factory('revGeocodeService',['$q',revGeocodeService]);

}());
