It's impossible to submit features pull requests ultil this is fixed.

To reproduce:

git clone https://github.com/mjbellantoni/formtastic-bootstrap.git
cd formtastic-bootstrap
bundle install
bundle exec rake spec

Seems to be ~/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/rspec-rails-3.1.0/lib/rspec/rails/adapters.rb:23:in require: cannot load such file -- test/unit/assertions

If you can submit a PR to resolve this issue I would be happy to merge it.
