在 Jasmine 中调用服务方法

Question

使用 Angular 和 Jasmine 我想运行带有一些模型数据的服务方法。下面是我的测试代码，它使用一些正在工作的 RoomsController 尝试运行 RoomsParamsSvc 上的 test() 方法：

describe('Rooms Controller', function() { 
    var RoomsController,
        scope,
        location,
        httpBackend,
        RoomsParamsSvc;    
    beforeEach(module('rooms', function ($provide, $injector) {                    
        RoomsParamsSvc = function () { //(1a)
            return $injector.get('RoomsParamsSvc'); //(1b)
        };         //(1c)
        $provide.value('RoomsParamsSvc', RoomsParamsSvc);   //(1d)
    }));
    beforeEach(inject(function($controller, $rootScope, $location, $httpBackend, _RoomsParamsSvc_) {
            // Set a new global scope
            scope = $rootScope.$new();
            location = $location;
            httpBackend = $httpBackend;
            RoomsParamsSvc = _RoomsParamsSvc_;
            RoomsController = $controller('RoomsController', {
                $scope: scope,
                $location: location,
                RoomsParamsSvc: RoomsParamsSvc
            });
        }));
    it('should have test as a function', function () {       
        var t = RoomsParamsSvc.test();
    });
});

据我对 with 注入器的了解，我应该能够使用注入的服务。没有 (1a-1d) 我得到一个错误：

Error: [$injector:unpr] Unknown provider: RoomsParamsSvcProvider <- RoomsParamsSvc

不过现在也行不通了。我得到一个错误，意思是 test() 不是一个函数：

jasmine typeerror 'undefined' is not a function (evaluating 'RoomsParamsSvc.test()')

我的服务是这样的：

var roomsApp = angular.module('rooms', []);
roomsApp.factory('RoomsParamsSvc', function () {
    var factory = {};    
    factory.test = function ()
    {
        return '';
    }
    return factory;
});

你有什么建议吗？

第 1a-1d 行不是必需的，因为 'RoomsParamsSvc' 已加载到您的 'room' 模块中。但是您引用了未定义的 RoomsController。

beforeEach(module('rooms'));
beforeEach(inject(function($controller, $rootScope, $location, $httpBackend, _RoomsParamsSvc_) {
        // Set a new global scope
        scope = $rootScope.$new();
        location = $location;
        httpBackend = $httpBackend;
        RoomsParamsSvc = _RoomsParamsSvc_;
        RoomsController = $controller(function() {}, {
            $scope: scope,
            $location: location,
            RoomsParamsSvc: RoomsParamsSvc
        });
        console.log(RoomsParamsSvc);
    }));
