gistfile1.js

/**
 * Pauses the tests execution until the named event is notified on the given
 * element, or a timeout is reached.

 * @param event
 * @param onElement
 * @param timeout
 */
var waitsForEvent = function(event, onElement, timeout) {

	timeout = timeout || 10000;
	
	var eventFired = null;

// Usage example:
// waitsForEvent('load', iframe);
