That said, Puppet shifted traditional infrastructure management more towards software development because we are developing Config as Code, even if it’s declarative.
This shift brings new challenges. A Puppet codebase can become too big, complex, and monolithic. We have to test our code, but how should we do it, and when?
We’ve seen many cases where there is no Unit test (Rspec) for puppet modules and manually executed Catalog compilation tests that could take hours or even days, depending on the size of the codebase.

In my life as a developer I tried to understand why people want to make certain choices for languages and tools. I don’t want to go pick a tool or language just because people order me to do that. I always wonder why they do that. Is it policy or is did they actually think of it.
I mean I understand why people want to use Typescript from certain perspectives.
