Travis CI Setup for Plain Old Ruby

Published on:

I recently wanted to setup some automated testing for a mini project I was working on. I was using regular Ruby and wanted to try working with Travis CI. For public projects, this is a great free resource which I cannot recommend enough.

They have a decent amount of documentation on how to setup your project. However, it took me longer than I thought necessary to get a basic Ruby project configured.

In the end, it came down to needing three things:

  • The rake gem present in either a Gemfile or *.gemspec file

  • A .travis.yml file

language: ruby
rvm:
  - 1.9.2
  - 1.9.3
  • A Rakefile with a default task to run the tests

#!/usr/bin/env rake
require "bundler/gem_tasks"

require 'rspec/core/rake_task'

desc 'Default: Run specs.'
task default: :spec

desc 'Run specs'
RSpec::Core::RakeTask.new do |task|
  task.rspec_opts = "--format doc"
end

Just drop those two files into your project directory and you are ready to experience the fun of CI.
