单元测试AngularJS $窗口服务 [英] Unit testing the AngularJS $window service

问题描述

我想单元测试以下AngularJs服务：

  .factory（'HTT presponseInterceptor'，['$ Q'，'$的位置，$窗口'，'CONTEXT_PATH'，函数（$ Q $位置，$窗口的contextPath）{
     返回{
         回应：功能（响应）{
             //将只要求HTTP高达300
             返回响应;
         }，
         responseError：函数（拒绝）{
             如果（rejection.status === 405 || rejection.status === 401）{
                 $ window.location.href =的contextPath +'/登入';
             }
             返回$ q.reject（拒绝）;
         }
     };
}]）;
 

我曾尝试用下面的套件：

 描述（'控制器'，函数（）{
    变量$范围，CTRL;
    beforeEach（模块（'curriculumModule'））;
    beforeEach（模块（'curriculumControllerModule'））;
    beforeEach（模块（'curriculumServiceModule'））;
    beforeEach（模块（函数（$提供）{
       $ provide.constant（'CONTEXT_PATH'，'bignibou'）; //这里覆盖的contextPath
    }））;
    描述（CreateCurriculumCtrl'，函数（）{
        VAR mockBackend，位置，_window;
        beforeEach（注（函数（$ rootScope，$控制器，$ httpBackend，$位置$窗口）{
            mockBackend = $ httpBackend;
            位置= $位置;
            _window = $窗口;
            $范围= $ rootScope $新的（）。
            CTRL = $控制器（'CreateCurriculumCtrl'，{
                $范围：$范围
            }）;
        }））;        它（'应该重定向到/登入如果401或405'，函数（）{
            mockBackend.whenGET('bignibou/utils/findLanguagesByLanguageStartingWith.json?language=fran').respond([{\"description\":\"Français\",\"id\":46,\"version\":0}]);
            mockBackend.whenPOST（'bignibou /课程/新）。反应（功能（方法，URL，数据报头）{
                返回[401];
            }）;
            $ scope.saveCurriculum（）;
            mockBackend.flush（）;
            期待（_window.location.href）.toEqual（/ bignibou /登入）;
        }）;
    }）;
}）;
 

然而，它失败，出现以下错误信息：

  PhantomJS 1.9.2（Linux）的控制器CreateCurriculumCtrl应该重定向到/登入如果401或405失败
    预期的http：//本地主机：9876 / context.html'等于'/ bignibou /登入。
PhantomJS 1.9.2（Linux）的错误
    你的一些测试做了全面的重新加载页面！
 

我不知道什么错误，为什么。任何人都可以请帮助？

我只是想确保 $ window.location.href 等于 / bignibou /登入

编辑1

我设法得到它的工作方式如下（感谢dskh）：

  beforeEach（模块（'配置'，函数（$提供）{
      $ provide.value（'$窗口'，{位置：{HREF：'假'}}）;
 }））;
 

解决方案

当您在模块中加载你可以注入模拟的依赖关系：

  angular.mock.module（'curriculumModule'，函数（$提供）{
            $ provide.value（'$窗口'，{位置：{HREF：'假'}}）;
        }）;
 

I would like to unit test the following AngularJs service:

.factory('httpResponseInterceptor', ['$q', '$location', '$window', 'CONTEXT_PATH', function($q, $location, $window, contextPath){
     return {
         response : function (response) {
             //Will only be called for HTTP up to 300
             return response;
         },
         responseError: function (rejection) {
             if(rejection.status === 405 || rejection.status === 401) {
                 $window.location.href = contextPath + '/signin';
             }
             return $q.reject(rejection);
         }
     };
}]);

I have tried with the following suite:

describe('Controllers', function () {
    var $scope, ctrl;
    beforeEach(module('curriculumModule'));
    beforeEach(module('curriculumControllerModule'));
    beforeEach(module('curriculumServiceModule'));
    beforeEach(module(function($provide) {
       $provide.constant('CONTEXT_PATH', 'bignibou'); // override contextPath here
    }));
    describe('CreateCurriculumCtrl', function () {
        var mockBackend, location, _window;
        beforeEach(inject(function ($rootScope, $controller, $httpBackend, $location, $window) {
            mockBackend = $httpBackend;
            location = $location;
            _window = $window;
            $scope = $rootScope.$new();
            ctrl = $controller('CreateCurriculumCtrl', {
                $scope: $scope
            });
        }));

        it('should redirect to /signin if 401 or 405', function () {
            mockBackend.whenGET('bignibou/utils/findLanguagesByLanguageStartingWith.json?language=fran').respond([{"description":"Français","id":46,"version":0}]);
            mockBackend.whenPOST('bignibou/curriculum/new').respond(function(method, url, data, headers){
                return [401];
            });
            $scope.saveCurriculum();
            mockBackend.flush();
            expect(_window.location.href).toEqual("/bignibou/signin");
        });


    });
});

However, it fails with the following error message:

PhantomJS 1.9.2 (Linux) Controllers CreateCurriculumCtrl should redirect to /signin if 401 or 405 FAILED
    Expected 'http://localhost:9876/context.html' to equal '/bignibou/signin'.
PhantomJS 1.9.2 (Linux) ERROR
    Some of your tests did a full page reload!

I am not sure what is going wrong and why. Can anyone please help?

I just want to ensure the $window.location.href is equal to '/bignibou/signin'.

edit 1:

I managed to get it to work as follows (thanks to "dskh"):

 beforeEach(module('config', function($provide){
      $provide.value('$window', {location:{href:'dummy'}});
 }));

解决方案

You can inject mock dependencies when you load in your module:

angular.mock.module('curriculumModule', function($provide){
            $provide.value('$window', {location:{href:'dummy'}});
        });
