Correct, but there is some kind of dependency here, to load the environment we need to require the application, but teaspoon doesn't load any assets by default, it does it in ``/= require application` in `test_helper.js`, and to get that we need that boot_partial.

Also Teaspoon mounts by default in development env too, so we can always go to /teaspoon without having to change the environment (It allows to do RAILS_ENV=test ...  too)
