Trying out $window.location.href in Karma with Angular testing

I'm currently working on properly injecting the $window service into my Angular controller, and then testing to ensure that it redirects correctly. However, I'm running into an issue where I'm getting an error message that says

undefined is not a constructor (evaluating 'expect(window.location.href).toEqual('/profile')')
. Here's a snippet of my Angular controller code:

login.submitLogin = function(){
    LoginFactory.loginUser(login.dataset)
        .then(function(response){
            $window.location.href = '/profile'
        },function(response) {
            login.errorMessage = response.data.message;
        });
};

My unit test in Karma looks like this:

describe('Login Controller', function() {

    var controller, window;

    beforeEach(angular.mock.module('app'));

    beforeEach(inject(function(_$controller_, _$window_){
        window = _$window_;
        controller = _$controller_('LoginCtrl',window);
    }));

    describe('Login', function() {

        it('expects controller to be defined', function(){
            expect(controller).to.be.defined;
        });

        it('expects to be redirected after login', function() {
            controller.dataset.username = 'username';
            controller.dataset.password = 'password';
            controller.submitLogin();
            expect(window.location.href).toEqual('/profile');
        });
    });
});

To address this issue, you can overwrite the $window service in your tests. This can be achieved by:

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

    beforeEach(inject(function(_$controller_, _$window_){
        window = _$window_;
        controller = _$controller_('LoginCtrl',window);
    }));

You can then verify what value has been assigned to $window.location.href by using:

expect(window.location.href).toEqual('/profile');

It is also recommended to utilize the $httpBackend if LoginFactory.loginUser sends requests to the server:

    it('expects to be redirected after login', function() {
        var mockedResponse = {};

        controller.dataset.username = 'username';
        controller.dataset.password = 'password';

        $httpBackend.whenPOST('/api/login/').respond(mockedResponse);
        controller.submitLogin();
        $httpBackend.flush();

        expect(window.location.href).toEqual('/profile');
    });
