Does notifyWhenNoOutstandingRequests or an equivalent exist in Angular 2?

Question

I have seen this used by test frameworks (for example, Arquillian) to detect when the dom is ready to be examined with Angular 1. Is there an equivalent way to do this in angular 2?

Answer 1

onEventDone from NgZone should work for that

Notifies subscribers immediately after the final onTurnDone callback before ending VM event.

This event is useful for validating application state (e.g. in a test).
