How to mock $window.location.replace in AngularJS unit test?

I've got the following service:

angular.module(services)

.factory(whatever, function($window) {

  return {

    redirect: function() {

      $window.location.replace(http://www.whatever.com);

    }

  };

});

How to mock $window object in unit test to prevent reloading the page when running tests?

I tried using

spyOn($window.location, 'replace').andReturn(true);

, but it didn't work (still got Some of your tests did a full page reload! error) and

$provide.value('$window', {location: {replace: jasmine.createSpy()}})

, but I was getting an error (Error: [ng:areq] Argument 'fn' is not a function, got Object) with stack trace pointing only to angular own source, so it wasn't very helpful...

In Chrome (didn't test inother browsers), location.replace is readonly so spyOn wasn't able to replace it.

$provide.value should work. Something must be wrong somewhere in your code.

Here is a working unit test

describe('whatever', function() {

    var $window, whatever;



    beforeEach(module('services'));



    beforeEach(function() {

      $window = {location: { replace: jasmine.createSpy()} };



      module(function($provide) {

        $provide.value('$window', $window);

      });



      inject(function($injector) {

        whatever = $injector.get('whatever');

      });

    });



    it('replace redirects to http://www.whatever.com', function() {

      whatever.redirect();

      expect($window.location.replace).toHaveBeenCalledWith('http://www.whatever.com');

    });

});
