I'm curious to if it would be valuable, I'd like to start using QUnit, but I really don't know where to get started. Actually I'm not going to lie, I'm new to testing in general, not just with JS.

I'm hoping to get some tips to how I would start using unit testing with an app that already has a large amount of JavaScript (ok so about 500 lines, not huge, be enough to make me wonder if I have regression that goes unnoticed). How would you recommend getting started and Where would I write my tests?

(for example its rails app, where is a logical place to have my JS tests, it would be cool if they could go in the /test directory but it's outside the public directory and thus not possible... err is it?)
