在AngularJS / Jasmine中注入Mock服务

我正在使用茉莉来测试我在TypeScript中编写的控制器.我的单元测试是用普通的 javascript.
当我测试我的控制器时,我收到一个错误,我想注入一个模拟服务.

这是我的测试看起来的样子：

'use strict';

describe('ConfigCtrl',function(){
    var scope,http,location,timeout,$httpBackend,service;

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

    beforeEach(angular.mock.inject(function($rootScope,$http,$location,$timeout,configService,$controller){

        scope = $rootScope.$new();
        http = $http;
        location = $location;
        timeout = $timeout;
        service = configService;


        $controller('configCtrl',{$scope: scope,$http: http,$location: location,$timeout: timeout,configService: service});
    }));

    it('should have text = "constructor"',function(){
        expect(true).toBe(true);
    });
});

我的app.ts：

module game {
    'use strict';

    var busybee = angular.module('busybee',[]);
    busybee.controller('configCtrl',ConfigCtrl);

    busybee.service('configService',ConfigService);
    ...
    ...

}

和我的TypeScript控制器：

module game {
    'use strict';

    export class ConfigCtrl {

        static $inject: string[] = ['$scope','$http','$location','$timeout','configService'];

        constructor($scope: ng.IScope,$http: ng.IHttpService,$location: ng.ILocationService,$timeout: ng.ITimeoutService,configService: game.ConfigService) {  
            //any code here
        }
    }   
}

当运行业力时,我收到以下错误：

Chrome 28.0.1500 (Linux) ConfigCtrl should have text = "constructor" FAILED
        TypeError: Cannot read property 'prototype' of undefined

看来,注入configService存在问题,但我不知道为什么.

编辑：添加了一个jsfiddle http://jsfiddle.net/Q552U/6/

更新：似乎茉莉花在不同文件中具有TypeScript类的编译javascript是一个问题.将TypeScript文件编译为单个.js文件(tsc –out dest.js source.ts),对我来说是这样的.

尝试使用$injector获取服务.

beforeEach(angular.mock.inject(function($rootScope,$controller,$injector){
    scope = $rootScope.$new();
    http = $http;
    location = $location;
    timeout = $timeout;
    service = $injector.get('configService'); //not sure the name,you may try 'ConfigService' as well.

    $controller('configCtrl',configService: service});
}));
