<h1>Asynchronous Event Testing</h1>
<div class="exampleIntro">
<p>This example shows how to create an asynchronous test with the YUI Test framework for testing browser-based JavaScript code.
A code>Y.Test.Case</code></a> object is created to test the
<code>Y.Anim</code> object. The test waits until the animation is complete
before checking the settings of the animated element.</p>
