From 5fb877b093e4b2a9ddc98d558fe92f66d26af149 Mon Sep 17 00:00:00 2001
From: Artur Signell <artur@vaadin.com>
Date: Mon, 7 Oct 2013 19:56:43 +0300
Subject: Makes test stable and adds helper comparison methods

* Takes into account that the timer can be triggered multiple times before the initial request is done (especially if the server is slow)
* Adds assertLessThan, assertLessThanOrEqual, assertGreaterThan, assertGreaterThanOrEqual to ease test creation
