Terry the tester needs a test environment for testing the Puppet modules that we developed in the development environment. A logical name for the test environment is test. You may recall that in Chapter 6, Scaling Up the Puppet Environment, we created a node group called development and associated it with the environment named development. We'll repeat this process and create a test node group, which we'll also associate with the development environment.

Why would we associate a test node group with the development environment? Shouldn't the test node group have its own environment called test?

Yes, we can do that, but then we will have to modify the bootstrap::master class, and add a file resource to it that creates an /etc/puppetlabs/puppet/environments/test directory for the new environment. This will give us a new environment with no Puppet modules in it.

As Terry's goal is to test the Puppet modules that we developed in the development environment, the best option...
