Fix: Include the following configuration in features/support/env.rb require 'webrat' require 'webrat/core/matchers' Webrat.configure do |config| config.mode = :rack config.open_error_files = false # Set to true if you want error pages to pop up in the browser end World(Webrat::Methods) World(Webrat::Matchers) This also fixes the error : "no such file to load -- action_controller/integration"
