My best suggestion is using alert() and in your Ruby code do

   browser.add_listener(:alert) { |page, message| ... }

That will probably get quite annoying when browsing the app manually  
though. It would be great to be able to do console.debug(...) in  
JavaScript and have HtmlUnit expose that log somewhere. However, http://htmlunit.sourceforge.net/javascript.html

If you can convince someone to add the console object to HtmlUnit's JS  
implementation, I'll be happy to add support for it in Celerity. Their  
mailing lists are at http://htmlunit.sourceforge.net/mail-lists.html :)
