Pain free coffeescript testing under Rails 3.1

Jasminerice

Utilizing (jasmine)[http://pivotal.github.com/jasmine/] and taking full advantage of the Rails 3.1 asset pipeline jasmine rice removes any excuse YOU have for not testing your out of control sprawl of coffeescript files. This project rocks and uses MIT-LICENSE.

Setup For Rails 3.1

This is a gem specifically for Rails 3.1. Just include it in your Gemfile so

gem "jasminerice"

Now add a route to the end of your config.routes but only for development and test

if ["development", "test"].include? Rails.env
	mount Jasminerice::Engine => "/jasmine" 
end

Create a single file called

spec/javascripts/spec.js.coffee

with the following content

#=require_tree ./

This pulls in all your

spec/javascripts/*_spec.js.coffee
spec/javascripts/*_spec.js
spec/javascripts/*_spec.js.erb
etc

into jasmine. For example

spec/javascripts/foo.js.coffe

#= require foo
#= require bar

describe "Foo", ->

	it "it is not bar", ->
		v = new Foo()

		expect(v.bar()).toEqual(false)

describe "Bar", ->

	it "it is not foo", ->
		v = new Bar()

		expect(v.foo()).toEqual(false)

The Rails 3.1 asset pipeline using sprockets and tilt ensure conversion. As well you can use the #require dependency mechanisms

Now start your server

rails s

Goto

http://localhost:3000/jasmine

and there are your specs.
