Even if your development workstation does match your production environment, you probably don’t want to take the risk of running untested Chef code locally. Untested Chef code might make unintended configuration changes to your local development environment. Neither is it a good idea to run your experimental Chef code in your production environment before it is validated, for similar reasons.
We’ll use Test Kitchen to create a sandbox environment that simulates a production environment. Test Kitchen works in concert with two other tools, Vagrant and VirtualBox, to produce a sandbox locally in a virtual machine. This sandbox environment is a safe, isolated place in which to experiment with Chef.
