What you are asking for is a way to test your API from the perspective of a
client ( like curl ) . I wanted to do the same thing in a project I worked
on, and I used Cucumber + Rack::Test + some JSON helper methods and I am
really happy with how it worked out. I've blogged about this here :
http://www.emilsoman.com/blog/2013/05/18/building-a-tested/ . I've set up
an example Rails 4 app with tests here :
https://github.com/emilsoman/rails-4-api . Hope that helps.
