Unit testing the AngularJS $window service

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'}}); })); ```
