[xwiki-users] Testing framework within XWiki pages

Hello all, I've been desiring a testing framework to aid my development efforts within XWiki pages. Specifically, I want to use test-driven development so that I can write tests for scripts before I write the scripts themselves. These tests would be harnesses (possibly using {{include document="Blah.Blah"}} and xwiki.parseGroovyFromPage("Blah.Blah")) and would report passes / failures / errors. There would also be a way to develop a suite of tests to run all at once, xUnit style. Before taking the time to develop this myself, has anyone developed something like this, or are there any recommendations or code you could share? Thanks, Joshua
