It’s sometimes useful to be able to perform a page redirect using AngularJS low-level $window API.
What’s not ideal is when this behaviour needs testing and the sucker actually performs a redirect half way through your suite leaving you in limbo – not cool!
This is where AngularJS liberal use of Dependency Injection(DI) really helps as we can utilise its inbuilt $provide service to stub out $window and overcome the issue.
Below is an example of how I achieved this in Jasmine / CoffeeScript:
ctrl = scope = $window = null
beforeEach ->
module 'my_module', ($provide) ->
$provide.constant '$window', { location: { href: "dummy" } }
inject ($rootScope, $controller, _$window_) ->
scope = $rootScope.$new()
$window = _$window_
ctrl = $controller 'MyController', $scope: scope
it "should redirect to '/some-other-url'", ->
expect($window.location.href).toEqual("dummy")
scope.myMethodWhichRedirects()
expect($window.location.href).toEqual("some-other-url")
