Terminal junkies rejoice! Now you can use Cucumber to test your command line interfaces just like you do for your web apps. Aruba from Cucumber creator Aslak Hellesøy provides familiar step definitions for testing output, exit statuses, and file system commands. Here’s an example feature file for testing exit statuses:
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
Aruba provides the exit status step:
Then /^the exit status should be (\d+)$/ do |exit_status| @last_exit_status.should == exit_status.to_i end
To use Aruba just install the gem
sudo gem install aruba
and then require it in your
env.rb or any file under
