我在想使用 $cookieStore 模块的地方提供服务。它工作正常，但是在单元测试时它会中断，并给出错误：“$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...)
}));
});

我在 karma 测试文件中包含了 angular-cookies。

知道为什么代码在运行时有效，但单元测试失败了吗？

更新：

从上面的评论来看，似乎对“ngCookies”的依赖是在一个单独的模块中声明的。

要解决此问题，请尝试在您的服务模块中声明它：

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

这是解决此问题的推荐方法。

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：

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 模块以使其正常运行。

我在使用 angular-cookies 和 angular-file-upload 时遇到了类似的问题。我是这样解决的：

首先，我检查了我的应用程序的所有依赖项bower list：

-bash-4.1$ bower list
bower check-new     Checking for new versions of the project dependencies..
 APPNAME#0.0.0 /home/git/APPNAME/test.git
 ├── angular#1.2.28 (1.4.4-build.4150+sha.39ff333 available)

 │ └── angular#1.2.28 (1.4.4-build.4150+sha.39ff333 available)
 ├─┬ angular-cookies#1.4.3 (1.4.4-build.4150+sha.39ff333 available)
 │ └── angular#1.2.28 incompatible with 1.4.3 (1.4.3 available, latest is 1.4.4-build.4150+sha.39ff333)
 ├─┬ angular-file-upload#1.2.0
 │ └── angular#1.2.28 (1.2.29-build.592+sha.b041b66 available, latest is 1.4.4-build.4150+sha.39ff333)

正如您将看到的，bower 告诉我 Angular 1.2.28 和 1.4.3 之间的不兼容，然后，我们遇到了库问题。angular-cookies 和 angular-file-upload 也是如此。

在那之后，我决定清理我所有的 bower_components 目录rm -fr bower_components并运行一个新目录bower install以确保所有库都是“全新安装的”。

-bash-4.1$ rm -fr bower_components
-bash-4.1$ cd ..

bower 让我在 angular 版本之间进行选择，我选择了第 7 个选项，因为它是 angular 1.4.3，这是我的应用程序的大多数组件所需的最新版本。之后，bower 进行了安装，并将 angular 1.4.3 链接到所有需要它的 bower_components：

正如您将看到的，我仍然在 angular-file-upload 组件中看到不兼容的依赖项。然后，我进入组件目录，并在本地为此组件安装了一个新版本的 angular（组件本身所需的）：

-bash-4.1$ cd client/
-bash-4.1$ cd bower_components/
-bash-4.1$ cd angular-file-upload/
-bash-4.1$ bower install angular --save
bower angular#*                 cached git://github.com/angular/bower-angular.git#1.4.3
bower angular#*               validate 1.4.3 against git://github.com/angular/bower-angular.git#*

Unable to find a suitable version for angular, please choose one:
    1) angular#~1.2.11 which resolved to 1.2.28 and is required by angular-file-upload
    2) angular#~1.4.3 which resolved to 1.4.3

Prefix the choice with ! to persist it to bower.json

? Answer: 1!
bower angular               resolution Saved angular#~1.2.11 as resolution

之后，一切正常，没有更多的注入或依赖问题。希望它可以帮助你。

OP 使用工厂创建了拦截器。但是，我正在修复一些代码，并且看到拦截器创建为提供者......

.provider('myHttpInterceptor', function 
    HttpInterceptorProvider($injector, _, apiConfig) {
                var self = this;
...

如果您遇到这种情况并偶然发现这个 SO 问题，这就是我解决问题的方法。

我尝试在函数中插入 $cookieStore，甚至尝试使用 $inject 但我不断收到 Unknown provider CookieStore （因此我是如何找到这篇文章的）

我解决问题的方法是找到 $get 方法并将其放入 cookie 存储中。

this.$get = function($q, $cookieStore, myCache) {
                return {
                    'request': function(config) {
...

回想起来，这与提供者配方文档非常一致。

关键是 angular.js 版本和 angular-cookies 版本必须相同。 在此处输入图像描述

在我匹配它们之后，它对我有用。
