Since the Ruby port of envjs is mothballed, capybara-envjs is as well. I suggest looking at something based on v8 and/or headless webkit.
capybara-envjs is a Capybara driver for the envjs gem (GitHub, rubygems.org). It is similar to Capybara’s rack-test driver in that it runs tests against your rack application directly but fully supports javascript in your application.
Install as a gem:
gem install capybara-envjs

See the Capybara docs. Use the symbol :envjs for the driver/default_driver as appropriate.
If you are using cucumber, you might add the following lines to your features/support/env.rb
require 'capybara/envjs' Capybara.javascript_driver = :envjs
