@bcardarella About putting it in config/environments/test.js.erb, that might not be the place since this is not related with the tests per se, but just telling teaspoon how to load and run every test https://github.com/modeset/teaspoon/blob/master/app/views/teaspoon/spec/runner.html.erb

Teaspoon has some other views which will anyways be under the load path, though they only work when used inside the engine.
