* Rails ships with Ruby test generators (because testing is good) * Rails ships with Javascript/Coffeescript generators * There's no Javascript testing framework in Ruby core, nor Rails. (testing is only good for Ruby code?)
I wasn't trying to say that Rails shouldn't encourage Javascript testing. But the fact that Rails does not ship a testing framework and, out of the box, encourages you to use the testing framework that is already on your machine should be noted. I can't recall ever seeing 3000+ word blog posts on getting Test/Unit to work with Rails as I have for other testing frameworks.
Ruby core may never include a Javascript testing framework but maybe this shouldn't be decided by a bunch of +1's on a thread right now. Since some of these features/tools are new to Rails maybe the best thing to do (as others have noted) is to see how the JS testing frameworks adapt and evolve before forming an opinion?
