Python Network Automation Dry Runs with Nornir, Scrapli, and Netmiko
Python network automation often starts as a script and slowly becomes a change platform. Before that happens, it needs tests, dry runs, and guardrails.

Source-of-truth automation is powerful because it changes the system that other automation trusts. That also makes it risky. A broken sync job can create bad devices, duplicate prefixes, wrong interface names, or stale custom fields.
APIs are great, but most networks still have a lot of operational truth hidden in CLI output. A useful NetDevOps pipeline can parse that output and test it like normal data.
Network automation usually breaks before it touches a router. The failure is often bad input data: a missing VLAN ID, an interface name typo, a wrong site slug, or a template variable that nobody supplied.
