Rails 3.1 & Jasmine: Including JavaScripts from gems

Question

I have a rails 3.1 project that I'd like to run some jasmine specs on. Problem is, my rails project requires some javascript files that are sourced from gems (most particularly backbone-rails), not my /assets directory.

Looking at the generated jasmine file's HTML, it's successfully including all assets from the JavaScripts /assets directory (compiled from coffeescript), but no javascript files generated by gems. Consequently I'm getting a bunch of 'class not found' errors.

So, any ideas on getting jasmine to require Rails 3.1 JavaScript files from gems, not just /assets? Current jasmine.yml included below. Any ideas appreciated

src_files:
  - public/javascripts/prototype.js
  - public/javascripts/effects.js
  - public/javascripts/controls.js
  - public/javascripts/dragdrop.js
  - public/javascripts/application.js
  - public/javascripts/**/*.js
  - spec/**/*_spec.js
  - "vendor/**/*.{js, coffee}"
  - "lib/**/*.{js, coffee}"
  - "app/**/*.{js, coffee}"

stylesheets:
  - stylesheets/**/*.css

helpers:
  - helpers/**/*.js

spec_files:
  - '**/*[sS]pec.{js, coffee}'

src_dir: assets

spec_dir: spec/javascripts

I highly recommend using jasmine-headless-webkit to do jasmine testing in rails 3.1 apps. Here's my jasmine.yml file:

src_dir: app/assets/javascripts
asset_paths:
- app/assets/templates
- lib/assets/javascripts
- vendor/assets/javascripts

src_files:
- [ 'application.js' ]

spec_dir: spec/javascripts

spec_files:
- "**/*[Ss]pec.*"

helpers:
- "helpers/**/*"

I'm using that with jasmine-headless-webkit to run my tests on the command-line (using watchr to run them automatically when a file is changed)

It's a wonderful way to test.

Fairly recent commits to jasmine master enable it to source javascripts from the asset pipeline. It works great.
