Used Ruby 2.3.0, Rails 4.2.0, AngularJS 1.4.8, Bootstrap 3
Devise used for authorization, RSpec + Capybara for tests
Keep in mind, that files you upload (comments attachments), will be deleted in a short term, or will not be saved at all, if they are large, because of Heroku file system settings, and you probably will not be able download these files.
I recommend using small txt files for testing uploading and downloading.
To run tests just run (you need installed firefox in your system)
rake spec
