[JWebUnit-users] Accessing dynamic images created in Javascript

[Jeff D. <jef...@ya...>]

Hi all,
   Another quick question. I have some javascript/JQuery that is creating an img 
dynamically. I tried using the assertElementPresentByXPath()method but that is 
not behaving as expected. For example, I have an Ajax call that builds the img 
tag as follows:

xmlhttp.onreadystatechange=function() {     if (xmlhttp.readyState==4 && 
xmlhttp.status==200) { 		try { 			tableHTML = "<h2>Administrators <img 
id=\"inviteAdmin\" title=\"Invite an administrator\" class=\"clickable\" 
src=\"images/icon_envelope.png\" onclick=\"showInviteAdministrator();\" 
width=\"48\" height=\"48\" alt=\"Invite administrator\"></img></h2><table>"; 
			result = JSON.parse(xmlhttp.responseText);

My JWebUnit test file then tries the following assert:

assertElementPresentByXPath("//img[@src='images/icon_envelope.png']");

Here is the resulting (truncated) trace when the assert fails:
junit.framework.AssertionFailedError: Unable to locate element with xpath 
"//img[@src='images/icon_envelope.png']" 	at 
junit.framework.Assert.fail(Assert.java:47) 	at 
junit.framework.Assert.assertTrue(Assert.java:20) 	at 
net.sourceforge.jwebunit.junit.WebTester.assertElementPresentByXPath(WebTester.java:2034)
 	at 
net.sourceforge.jwebunit.junit.WebTestCase.assertElementPresentByXPath(WebTestCase.java:1619)
 
Now I am reasonably good with XPath, but I also know how finicky it can be and 
how easy it is to overlook something. Here are my questions:

	* Am I even going about this the right way? 
	* Can JWebUnit handle dynamic elements created by javascript?
	* Is this something HtmlUnit is better suited?

Thanks in advance for your help.
