*.hamlc templates are great. jasmine-headless-webkit (JHW) is great. But getting the two working together is a pain.

There's a good chance you see something like window.HAML is undefined.

# spec/javascripts/helpers/spec_helper.rb require 'sprockets' require 'haml_coffee_assets' require 'haml_coffee_assets/tilt/template_handler' # JHW does not support ERB templates. However, haml_coffee_assets uses ERB # templates for its config.

Make sure you require hamlcoffee in your javascript/coffeescript.
