angularjs - 在 AngularJS/Jasmine 中注入(inject) Mock 服务

Question

我正在使用 jasmine 来测试我用 TypeScript 编写的 Controller 。我的单元测试是用普通的 javascript 编写的。 我在测试我的 Controller 时遇到错误，我想在其中注入(inject)模拟服务。

这是我的测试结果:

'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);
    });
}); 

我的应用程序:

module game {
    'use strict';

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

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

}

和我的 TypeScript Controller :

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
        }
    }   
}

运行 karma 时，出现以下错误:

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

似乎注入(inject) configService 时出现问题，但我不知道为什么。

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

更新:对于 jasmine 在不同文件中具有 TypeScript 类的已编译 javascript 而言，这似乎是一个问题。将 TypeScript 文件编译为单个 .js 文件 (tsc --out dest.js source.ts)，帮我完成了。

尝试使用 $injector 获取服务。

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

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