btelles / api-test-needs-custom-event.html

When writing a test that needs to speak to an appengine endpoint, it's difficult to make the test wait for a response from a server. I've tried a bunch of permutations on waiting for "ready" on various elements, and triggering stuff. but I keep having to go back to writing a custom event and triggering it as below.

	<test-fixture id="basic">
	<template>
	<r-api path="api.widget.list"></r-api>
	</template>
	</test-fixture>

	<dom-module id="fake-google-api">
	<template>
	<iron-ajax id="widgetList"
	auto
