Hi Jeff,
Firstly yes, JWebUnit/HtmlUnit handles most types of Javascript, so it
should be fine as long as your Javascript is compliant.
Yes, using an XPath approach sounds fine. Have you tried searching through
all //img, and making sure your image is first present there? Perhaps the
@src attribute has whitespace or the URI is automagically made absolute, try
using contains() instead.
You could also first assert that the H2 exists (through XPath or an element
ID) and then assert that it contains an image, and then peeking at the
source of the image that way.
Hope this helps,
Jevon
