Just cloned this project and I get the following js error :
a.replace is not a function
Is it still possible to unit test coffeescript directly with Qunit ? I can't make it work.
@AngeliqueVille Can't help you there. I haven't tried working on this in a while so you're on your own.
@AngeliqueVille - I did it not three weeks ago, and it works fine for me. See my blog post (linked from an earlier comment) on how I did it.

With
Coffee.load
you can pass a callback as a second argument, which I'm using to guarantee that my test file gets loaded after the code that it's testing. I wrote it up here: http://effectif.com/coffeescript/qunit-boilerplate@elithompson – With this approach I've not had any trouble loading files off disk, rather than over HTTP. Maybe
Coffee.load
behaves differently to jQuery's AJAX handler here?
