-Jester depends on two libraries: Prototype, which comes with Rails and most people are familiar with, and ObjTree, a nice DOM parsing engine for JavaScript. Both of these are packaged along with Jester in this repository, so you don't have to hunt for them yourself. Just make sure you're including all three in your test file.
