Mock Iframe element in Jasmine and AngularJS

I am writing a directive unit test using jasmine to test whether the directive in question when applied on an iframe element, would actually bind all the children elements of the iframe(documentContent children actually).

What here is really hard to simulate is the actual iframe element. Executing the test where the iframe would really have to load external website could take a lot of time. Is there maybe an alternative solution, instead of using real frame element ?
