Testing is basic in devops/SRE. How are you going to ensure reliability if you cannot test the shit out of it?

The issue is there’s no formal tool or practices for testing in ops. DSL languages are limited forcing you to use several for different kind of scenarios. At the end you need to rely in a real programming language to parse different format files and ensuring your variables are correct. I think developing software for operations is exciting which is going to mature with time. Kubernetes(and its CRD) is a step forward
