Looking for the HTML features decription?
The Cucumber features that documented the gem behaviour until v1.5.1 constituted a robust tests suite, but they were slow and writting them was difficult enough to become a continuous bottleneck.
I decided to tackle the issue by replacing most scenarios by unit tests (see #104), and since v1.5.2 the gem behaviour is documented using RSpec only.
I liked the executable documentation idea, and I do not discard using Cucumber again to test Simple Token Authentication. However, truth is that neither the somewhat intricated Cucumber - Aruba - RSpec setup or the steps I wrote were exemplary enough to make justice to the great tool Cucumber is. So I decided to stop maintaining the features and to remove them. The RSpec test suite provides a nice documentation, and sometimes the best is a fresh start.
