The Puppet Development Kit doesn't just set us up to create well-written modules—it also lets us write unit tests for our modules and ensure the changes we expect are being made when we run our Puppet code. This is done through the use of RSpec, a Ruby-based testing framework, and the rspec-puppet and rspec-puppet-facts plugins. RSpec uses behavior-driven development concepts to check the end state of our code. These tests are written in a human-readable language based on Ruby.

By writing unit tests for our modules, we can ensure we're putting forth the highest-quality modules and prevent any unexpected production issues. Unit tests essentially work as another layer of protection against poor code, typos, and all the other gremlins that can end up in our modules.

What are Hands-On Labs?

Hands-On Labs are scenario-based learning environments where learners can practice without consequences. Don't compromise a system or waste money on expensive downloads. Practice real-world skills without the real-world risk, no assembly required.
