I have a rails app that is morphing into prodominately a browser-side Coffeescript app.  I have been using Konacha (https://github.com/jfirebaugh/konacha) for Coffeescript unit testing in the browser.  Konacha uses Mocha (http://visionmedia.github.com/mocha/) and chai (http://chaijs.com) for the test language and matchers.  Konacha has worked out well, but since I spend most of my development time developing Coffeescript, I want to use Rubymine's unit testing interface.  I tried (unsuccessfully) to get my test suite working with the jsTestDriver suite.  Has anyone else managed to get this combination working?  What is the least painful way to migrate to a solution that uses jsTestDriver?
