Jasmine and spy method - angularjs

Question

angular.module('mine', []).factory('MyFactory', ['$http', '$q', function
MyFactory($http, $q) {
return {
getData: function() {
var deferred = $q.defer(),
url = "http://...";
$http.jsonp(url)
.then(
function(response) {
deferred.resolve(response.data);
},
function(error) {
return $q.reject('Error retrieving data');
}
);
return deferred.promise;
}
};
}
]);
function MyController(MyFactory) {
var self = this;
self.getData = function() {
MyFactory.getData().then(
function(result) {
self.contacts = result;
},
function(error) {
console.log('Error retrieving data: ', error);
}
);
};
}
I am trying to unit test if data from factory go correctly to controller. Here is my unit testing code using Jasmine:
describe('component', () => {
let $componentController,contactsList,ctrl,$q,$rootScope;
beforeEach(angular.mock.module('mine'));
beforeEach(inject((_$componentController_,_MyFactory_, _$q_, _$rootScope_) => {
$componentController = _$componentController_;
ctrl = $componentController('myComponent',null);
$q = _$q_;
contactsList = _MyFactory_;
$rootScope = _$rootScope_;
}));
it('should ... ', function() {
spyOn(contactsList, "getData").and.returnValue(
$q.when({
message: 'awesome message'
}));
ctrl.getData();
$rootScope.$apply();
expect(ctrl.contacts.message).toBe('awesome message');
});
});
However, I am doing something wrong and I am getting the error: I am getting the following error: Possibly unhandled rejection: Error retrieving data thrown.I guess the problem lies on spy method. I'd appreciate any help.
