I would concur with some of the users above - A solid set of documentation would, for me, be a fantastic resource. My personal problems / issues would be addressed with the following (and I appreciate they are *my* issues, as a newcomer to automated testing and a newcomer to soapUI, Java, groovy):
A comprehensive reference to what objects exist in groovy in the soapUI context, and their methods and properties
Some good getting started docs for groovy
A more detailed / starting simpler tutorial on data driven testing
Basically, a nice big, fat book would be lovely ! <grin>
Instead, I'm going to end up posting lots of queries on this board, which is good I suppose for those facing similar confusion, but bad for all those people who will look and go "Oh no, another noob asking the same dumb questions we've seen a million times before", simply because my search-foo is not good enough to see appropriate earlier posts.
