Karma错误参数不是函数，未定义

Question

我是angularjs中的业力和茉莉花测试新手。我正在使用angularjs 1.2.13版本。我想测试我的控制器＆＃34; LandCtrl＆＃34;。在我的控制器规范文件中

   describe('Users factory',function(){
    var LandCon;
     beforeEach(angular.mock.module('routerApp'));

  beforeEach(inject(function(_UserAuth_) {
    LandCon = _UserAuth_;
  }));



  var $controller,$cookies,$timeout,$state,$scope;
  var userauth,searchfood;//$scope, UserAuth, $cookies, $state, searchFood, $rootScope, $timeout

beforeEach(inject(function(_$controller_,_UserAuth_,_$cookies_,_$state_,_searchFood_,_$timeout_,_$rootScope_){
    scope = _$rootScope_.$new();
    $controller = _$controller_;
    cookies = _$cookies_;
    state = _$state_;
    userauth = _UserAuth_;
    serchfood = _searchFood_;
    timeout = _$timeout_;
    landCtrl = $controller('LandCtrl',{$scope:scope,UserAuth:userauth,$cookies:cookies,$state:state,serchFood:serchfood,$rootScope:_$rootScope_,$timeout:timeout}).on(error,function(er){console.log(er);});
}));

 it('should be defined', function(){

     expect(landCtrl).toBeDefined();
 });  
});

我的控制器文件看起来像

routerApp.controller('LandCtrl', ['$scope', 'UserAuth', '$cookies', '$state', 'searchFood', '$rootScope', '$timeout', function ($scope, UserAuth, $cookies, $state, searchFood, $rootScope, $timeout) {

            $scope.Islocation = "";
            $rootScope.showMessage = false;
            $scope.location = {};
            var d = new Date();
            var yy = d.getFullYear();
            var mm = d.getMonth() + 1;
            var dd = d.getDate();
            if (mm < 10) {
                mm = "0" + mm;
            }
            if (dd < 10) {
                dd = "0" + dd;
            }
            var defaultdate = yy + "-" + mm + "-" + dd;
            //var defaultdate = "2017-01-19";

            $scope.LandsessionStatus = function () {
                return UserAuth.sessionStatus();
            };

            $scope.LandsessionUser = function () {
                return UserAuth.sessionUser();
            };

            $scope.Fn_logout = function () {
                UserAuth.logout();

            };

            $scope.Fn_openmenuClick = function () {

                if (searchFood.SetCookieData($scope.location) === 1 && $scope.place != undefined && $scope.place != '') {
                    $state.go('home');
                } else {
                    $rootScope.showMessage = true;
                    $timeout(function () {
                        $rootScope.showMessage = false;
                    }, 5000);
                }

            };

            $scope.Fn_ChangePlace = function (latitude, longitude, countrycode) {
                $scope.location.latitude = latitude;
                $scope.location.longitude = longitude;
                $scope.location.countrycode = countrycode;
                $scope.location.place = $scope.place;
                searchFood.SetCookieData($scope.location);
            };

            $scope.initDeliveryLocation = function(){
                var location = searchFood.GetCookieData();
                $scope.place = location.place;
                $scope.location = location;
            };
          $scope.initDeliveryLocation();
        }
    ]);

on karma start，显示以下错误
