Feature: exit statuses
 
  In order to specify expected exit statuses
  As a developer using Cucumber
  I want to use the "the exit status should be" step
 
  Scenario: exit status of 0
    When I run "ruby -h"
    Then the exit status should be 0
    
  Scenario: non-zero exit status
    When I run "ruby -e 'exit 56'"
    Then the exit status should be 56

steps.rb

Then /^the exit status should be (\d+)$/ do |exit_status|
  @last_exit_status.should == exit_status.to_i
end
