Installing Test Kitchen
Okay let's get down to it, shall we? Test Kitchen is packaged and delivered to you as a RubyGem. If you've used Chef, Puppet, or Rails before then working with Gems shouldn't present a huge challenge. If all this Ruby "stuff" is new, then don't despair–we're going to steer clear of a lot of Ruby-looking code.
To follow this guide there is some software that we will need in order for Test Kitchen to do its thing:
- A Ruby distribution - version 1.9 and higher
- Git - oh yes, we're going to be commiting code
- Vagrant - a great tool to help manage development virtual machines
- VirtualBox - a virtualization tool that let's you run virtual machines locally
I know, it sounds like a lot of work but fear not. It's not overly tricky to get going, and the folks over at the #learnchef website have a handy Workstation Setup that we can follow to get us started. Take a few minutes to get your software setup and if you run into any issues there should be some smart and capable people in the #learnchef IRC chatroom to get you back on track.
All done? Great! Open a terminal window and let's get started.
Installing Test Kitchen from RubyGems goes like this:
$ gem install test-kitchen Successfully installed mixlib-shellout-1.2.0 Fetching: net-ssh-2.7.0.gem (100%) Successfully installed net-ssh-2.7.0 Fetching: net-scp-1.1.2.gem (100%) Successfully installed net-scp-1.1.2 Fetching: safe_yaml-0.9.7.gem (100%) Successfully installed safe_yaml-0.9.7 Fetching: thor-0.18.1.gem (100%) Successfully installed thor-0.18.1 Fetching: test-kitchen-1.0.0.gem (100%) Successfully installed test-kitchen-1.0.0 6 gems installed
Now if the version of Test Kitchen is important to you, then you can add a
-v <version_string> to the end of the
gem install command. Alternatively if you prefer living on the edge, adding a
--pre to the install command will give you the latest alpha/beta/release candiate release. Note that these releases may not be as stable but your courage and feedback is greatly appreciated.
|If you are familiar with and use Bundler then you can safely add
Now let's verify that Test Kitchen is installed. To save on typing, the tool's main command is
kitchen. So to get the currently installed version we type:
$ kitchen version Test Kitchen version 1.0.0
