WebTest in Grails 
The upcoming Grails project will include sophisticated support for Canoo WebTest.
Grails is an open-source application framework based on Groovy. see
http://grails.codehaus.org .
Grails allows easy defintion of domain classes, views, and controllers from scaffolded artifacts. For these artifacts, it also scaffolds WebTests, see
http://grails.codehaus.org/Functional+Testing .
Grails is comparable to Ruby on Rails but runs on the Java platform and leverages the power of J2EE, Spring, and Hibernate. It even works with existing Java domain classes and mappings.
