While the (TestRail)[http://www.gurock.com/testrail/] Ruby client for their V2 API is available (on Github)[https://github.com/gurock/testrail-api], it isn't available as a gem. Ain't nobody want to be copying and pasting API clients into their projects.
And thus, zachpendleton/testrail was born. It's a gem wrapped around the example Gurock client.
Add this line to your application's Gemfile:
gem 'testrail', git: 'git://github.com/zachpendleton/testrail.git'And then execute:
$ bundle
