利用 jasmine + karma编写angularjs的controller单元测试用例 一直报错

Question

我利用 jasmine + karma编写angularjs的controller单元测试用例，一直报错：Error: [ng:areq] Argument 'roleCtrl' is not a function, got undefined,
大伙帮忙看看啥问题？

源码如下：

（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": "权限说明", "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) {
        //模拟生成scope, $rootScope是angular中的顶级scope，angular中每个controller中的     
        //scope都是rootScope new出来的
        scope = $rootScope.$new();
        //模拟生成controller 并把先前生成的scope传入以方便测试
        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
// Generated on Tue Mar 21 2017 12:39:40 GMT+0800 (CST)

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

        // base path that will be used to resolve all patterns (eg. files, exclude)
        basePath: '',

        // 设置输出测试内容文件的信息

        // ],
        // start these browsers

        browsers: ['Chrome'],



        // Continuous Integration mode
        // if true, Karma captures browsers, runs the tests and exits
        singleRun: false,

        // Concurrency level

        concurrency: Infinity,
        //webpack: require('./webpack.config')(true)
        webpack: {
            module: {
                loaders: [{
                        test: /\.js$/,
                        loader: 'babel',
                        exclude: /node_modules/,
                        query: {
                            presets: ['es2015']
                        }
                    }]
                    //plugins: ['node_modules/angular/angular.js', 'node_modules/angular-ui-router/release/angular-ui-router.js', 'node_modules/angular-mocks/angular-mocks.js']
            }
        }
    })
}

没人遇到这种问题么？

Answer 2

谢谢邀请，大概看了看，可能是spec.js里面没有roleCtrl声明的代码吧，你加上试试？

这方面经验较少，我表示我一直没有使用过ng中的$mock服务写一些单元测试，不是不想写，是真没有时间写。
