For testing purposes, I\'m creating Observable objects that replace the observable that would be returned by an actual http call with H

What you want is a timer:

// RxJS v6+
import { timer } from 'rxjs';

//emit [1, 2, 3] after 1 second.
const source = timer(1000).map(([1, 2, 3]);
//output: [1, 2, 3]
const subscribe = source.subscribe(val => console.log(val));
