未知提供者 CookieStore [英] Unknown provider CookieStore

问题描述

我正在使用 $cookieStore 模块提供服务.它工作正常，但在单元测试时它会中断，并给出错误:$cookieStoreProvider <- $cookieStore <- filtersService".

I am having service where I want to use the $cookieStore module. It works fine, but when unit testing it breaks, and gives the error: "$cookieStoreProvider <- $cookieStore <- filtersService".

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:

And the unit test service looks like this:

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...)
}));
});

我在 karma 测试文件中包含了 angular-cookie.

I have included angular-cookies in the karma test file.

知道为什么代码在运行时可以工作，但单元测试失败了吗?

Any idea why the code works when running, but unittests fails?

推荐答案

从上面的评论来看，对 'ngCookies' 的依赖似乎是在一个单独的模块中声明的.

From the comments above, it seems the dependency on 'ngCookies' is declared in a seperate module.

要解决此问题，请尝试在您的服务模块中声明它:

To fix this try declaring it in your service module:

var serviceModule = angular.app('App.services', ['ngCookies']);

这是修复此问题的推荐方法.

This is the recommended way of fixing this.

如果由于某种原因，您无法更改 serviceModule 定义，您也可以在单元测试中再次声明它:

If, for some reason, you could not change the serviceModule definition, you could also declare it again in your unit tests:

beforeEach(module('ngCookies','App.services'));

但是，我建议您在代码库中更改它，以便您的 serviceModule 不依赖于您的主 App 模块才能正常运行.

However i would recommend you change it in your code base so your serviceModule does not depend on your main App module for it to function properly.
