我利用 jasmine + karma編寫angularjs的controller單元測試用例，一直報錯：Error: [ng:areq] Argument 'roleCtrl' is not a function, got undefined,
大伙幫忙看看啥問題？

源碼如下：

（1）：roleCtrl

import ngApp from '../components/app';

export default ngApp.controller('roleCtrl', ['$scope', function($scope) {

    $scope.columns = [
        { "title": "角色", "attribute": "roleName", "type": "data" },
        { "title": "權限說明", "attribute": "description", "type": "data" }
    ];

    $scope.url = "/api/role/search/find";
    $scope.catalog = "role";
    $scope.param = { "systemCode": localStorage.syscode, page: 0, size: 10, isDelete: false };
}]);

（2）：spec.js

'use strict';
angular.module('ngApp', ['ui.router'])
    .value('rolefactory', 'rolefactory')
    .value('dialogService', 'dialogService');

describe("ngApp Unit Test", function() {
    beforeEach(angular.mock.module("ngApp"));
    var scope, ctrl;
    beforeEach(inject(function($controller, $rootScope) {
        //模擬生成scope, $rootScope是angular中的頂級scope，angular中每個controller中的     
        //scope都是rootScope new出來的
        scope = $rootScope.$new();
        //模擬生成controller 并把先前生成的scope傳入以方便測試
        ctrl = $controller('roleCtrl', { $scope: scope });
    }));
    // controller test
    describe('role controller test', function() {
        it('Add Cat Controller test', function() {
            expect(50).toBe(50);
        })
    })

});

（3）：karma配置

// Karma configuration

module.exports = function(config) {
    config.set({

            }
        }
    })
}
