未知的提供者CookieStore

我在要使用$ cookieStore模块的地方提供服务。它可以正常工作，但是在单元测试时会中断，并显示错误：“ $ cookieStoreProvider <-$ cookieStore <-filtersService”。

该服务如下所示：

serviceModule.factory('filtersService', ['$rootScope', '$location', '$cookieStore', function($rootScope, $location, $cookieStore){
    return {
        getFilters: function(){...}
}

单元测试服务如下所示：

describe('filtersService tests', function(){
var filtersService;
beforeEach(module('App.services'));

beforeEach(inject(function(filtersService, urlService, $location){

    filtersService = filtersService;
    urlService = urlService;
}));

it('test something', inject(function(filtersService, $location){
    filtersService.getFilters();
   expect(...something...)
}));
});

我已在业力测试文件中包含了angular-cookie。

知道为什么代码在运行时可以运行，但是单元测试失败了吗？
