How to use $ rootScope. $ on?

1

I do not know how to set $ rootScope. $ on in my unit test. Whenever I invoke a function it gives me the following error:

  

TypeError: Attempted to assign to readonly property.

The test is being done as follows:

describe('Testing EventHandler', function () {
 beforeEach(module('app'));

 var srv, rootScope, injector, httpBackend, animate, scope, location, loginService ;

 beforeEach(inject(function (EventHandler,_$injector_, $rootScope, $httpBackend, $animate, $location, LoginService) {
  injector = _$injector_;
  srv = EventHandler;
  rootScope = $rootScope;        
  animate = $animate;
  location = $location;
  loginService = LoginService;

}));    

 it('testing if the initialize_component function is defined', function(){
    expect(srv.initialize).toBeDefined();
    spyOn(srv, 'initialize').and.callThrough();
    srv.initialize({$animate: animate});
}); 

From the function present in eventHandler.service.js

(function () {
'use strict';

angular.module("app")

    .service('EventHandler', EventHandler);

EventHandler.$inject = ['$rootScope', '$location', '$animate', '$state', '$stateParams', '$sanitize', '$q', '$uibModal', 'toastr',
    'storage', 'StorageService', 'LogService', 'LanguageResource', 'LoginService', 'StcpUtilsService', 'DAOService',
    'CSRF', 'Authorization', 'ShortcutService', 'data_login', 'PermissionsService', 'BusinessLogicService', 'DebugMode'
];
