 Testing of Puppet catalogs is faster than running the agent, but you need to be careful of the following limitations:
 
-0. Facts are not taken from a live agent run
+1. Facts are not taken from a live agent run
 
-  octocatalog-diff by default uses the facts reported from a node's more recent Puppet run. If you have made changes to custom facts, catalog testing will **NOT** be an adequate test of whether your custom facts worked. (You can still use octocatalog-diff to help predict changes to nodes based on changes to facts, by overriding facts on the command line.)

-  The catalog defines the state of the system, but it's up to the agent to determine how to bring the system to a point that matches the catalog. The agent is responsible for order of operations and actually making the change.

You change this in your new branch to 50 GB. octocatalog-diff will dutifully report this change to you. However, the agent will fail to make the change, because it is not possible to shrink a file system from 100 GB to 50 GB.

-  Consider that you are using a Puppet module that creates a file system. The current implementation of that module checks to see if *any* file system is present on the device, and creates a new file system there if no file system was present. You upgrade the module, and the new version checks to see if *the specified* file system is present on the device, and reformats the device with the specified file system (regardless of whether there was no file system or if there was an existing file system of a different type). There would be no catalog changes (hence octocatalog-diff would report nothing) because the catalog simply instructs the agent to create a file system of the specified type at the defined location. However, the actual implementation of those instructions has changed dramatically.
