JavaScript - Is There a Render Hook Test Function in JavaScript?

Jose started using live view when they were doing that project that Dashbit's doing and he made a bunch of improvements to the testing scenario, this testing scene in live view. And ever since then, it's just awesome. It's so easy to use. They don't introduce the browser, which just makes them really fast. I've kind of taken the approach of leaving my hook as absolutely thin as possible. If it takes any kind of dynamic config like that, I pass it from the server side so that I can test that kind of scenario better.
