pyATS

pyATS (Python Automation Test System) is an end-to-end test automation framework, primarily developed by Cisco, designed for network engineers. It provides a robust infrastructure for defining network topologies, running tests against network devices (multi-vendor compatible), and parsing device outputs into structured data using the integrated Genie library. The current version is 26.3, and it maintains an active release cadence with frequent updates to parsers and APIs. [1, 4, 15, 18]
