One of the great beauties of ChefSpec (and of course Chef) is that at
its heart it’s just Ruby. This means that at almost any point you can
reach into the standard Ruby development toolkit for your testing or
infrastructure development needs. Hopefully this little example will
be helpful to you.

Although you don’t need to know Ruby to be get started with Chef, a willingness to learn will be rewarded. This is especially true when it comes to testing. This post by Stephen Nelson-Smith provides a gentle introduction to an essential tool in the testing toolkit – stubs – that should be accessible to most Chef users.
