stop.rb

    # Usage:
    #  @wip @stop
    #  At the end of features/support/env.rb add the following line
    #  require File.expand_path(File.dirname(__FILE__) + '/stop')
    # $ cucumber -p wip


    After do |scenario|
      if scenario.failed? && scenario.source_tag_names.include?("@wip") && scenario.source_tag_names.include?("@stop")
        puts "Scenario failed. You are in rails console becuase of @stop. Type exit when you are done"
        require 'irb'
        require 'irb/completion'
        ARGV.clear
        IRB.start
      end
