For testing purposes, I\'m creating Observable objects that replace the observable that would be returned by an actual http call with H
Observable
H
It's little late to answer ... but just in case may be someone return to this question looking for an answer
'delay' is property(function) of an Observable
fakeObservable = Observable.create(obs => { obs.next([1, 2, 3]); obs.complete(); }).delay(3000);
This worked for me ...
