我有以下控制器 ViewMeetingCtrl.js

(function () {
    'use strict';
    angular.module('MyApp').controller('ViewMeetingCtrl', ViewMeetingCtrl);

    ViewMeetingCtrl.$inject = ['$scope', '$state', '$http', '$translate', 'notificationService', 'meetingService', '$modal', 'meeting', 'attachmentService'];

    function ViewMeetingCtrl($scope, $state, $http, $translate, notificationService, meetingService, $modal, meeting, attachmentService) {
        $scope.meeting = meeting;

        $scope.cancelMeeting = cancelMeeting;

        function cancelMeeting(meetingId, companyId) {
            meetingService.sendCancelNotices(companyId, meetingId)
                .success(function () {
                    $state.go('company.view');
                });
        }      
    }
})();

我能够成功地为 cancelMeeting（） 调用spyOn，但不能通过 sendCancelNotices 方法的调用来 实现
。我想要做的是，我想测试，只要 cancelMeeting（） 被调用，它调用 sendCancelNotices（）
方法。我知道我应该使用createSpy方法来执行此操作。但是我不确定该怎么做。

下面是测试用例ViewMeetingCtrlSpec.js

describe('ViewMeetingCtrl CreateSpy --> Spying --> cancelMeeting', function () {
        var $rootScope, scope, $controller , $q  ;


        var sendCancelNoticesSpy = jasmine.createSpy('sendCancelNoticesSpy');


        beforeEach(angular.mock.module('MyApp'));

        beforeEach(inject(function ($rootScope, $controller ) {
            scope = $rootScope.$new();
            createController = function() {
                return $controller('ViewMeetingCtrl', {
                $scope: scope,
                meeting : {}
                }); 
            };
            var controller = new createController();
        }));

        it("tracks that the cancelMeeting spy was called", function() {
            //some assertion
        });

});
