I received pull request from Bill Warner. He writes unittest which used test-kitchen and RSpec. This pull request is a great resource for me because I didn’t know how to write test code for cookbook. There are a lot of things I can obtain. I cannot say thank you enough. And I always glad to receive PR from anyone, anytime.

So after merging it, I want to run this test automatically. Continuous integration on TravisCI. That’s the way I always do after writing test code. But this time there is one obstacle to me. Vagrant. test-kitchen uses Vagrant inside travis-ci instance. So you have to install Vagrant. Until v1.5.0, Vagrant is provided through gems. But current Vagrant is distributed only as platform specific packages. This means you have to install Vagrant through debian package in case of travis-ci. What have we to do?

I found one simple way. You can install debian package from here. And Vagrant needs Oracle VirtualBox which is available with apt-get. So all you have to do is writing below script.

  - sudo apt-get update -q
  - sudo apt-get install -q virtualbox --fix-missing
  - sudo wget -nv https://dl.bintray.com/mitchellh/vagrant/vagrant_1.7.2_x86_64.deb
  - sudo dpkg -i vagrant_1.7.2_x86_64.deb
  - bundle install

This is a part of .travis.yml. install directive is used for configuration of build environment. The fact that we can use Vagrant virtual machine on travis-ci is very amazing to me. It reminds me of the powerful ci platform which is always stands by me. I cannot help keeping using ci hostring services such as TravisCI!
