# From http://railscasts.com/episodes/287-presenters-from-scratch?view=comments
# I added spec/support/presenters.rb file and I require it from spec_helper.rb:

RSpec.configure do |config|
  config.include ActionView::TestCase::Behavior, example_group: {file_path: %r{spec/presenters}}
  config.include RSpec::Rails::Matchers::RenderTemplate, example_group: {file_path: %r{spec/presenters}}
end

# Example:
presenter.method.should render_template('blah/_blah')

I wanted to figure out the fastest way to load non-critical CSS so that the impact on initial page drawing is minimal.

TL;DR: Here's the solution I ended up with: https://github.com/filamentgroup/loadCSS/

For async JavaScript file requests, we have the async attribute to make this easy, but CSS file requests have no similar standard mechanism (at least, none that will still apply the CSS after loading - here are some async CSS loading conditions that do apply when CSS is inapplicable to media: https://gist.github.com/igrigorik/2935269#file-notes-md ).

Seems there are a couple ways to load and apply a CSS file in a non-blocking manner:
