Railsers et al:

Anyone developing Ajax applications needs to read my new Short Cut, at  
O’Reilly:

[http://www.oreilly.com/catalog/9780596510657/](http://www.oreilly.com/catalog/9780596510657/)  
“Test Driven Ajax (on Rails)”

The paper shows how to write an Ajax website using these new assertions:

. assert\_xml - check that HTML is XHTML and parsable  
. assert\_xpath - parse XHTML and extract specific details  
. assert\_js - parse JavaScript (without Regexp!) for details  
. assert\_ajax - run assertions when an Ajax command completes

The paper shows how to grow a test runner in a web page. It tests a  
target  
website inside an IFRAME.
