pyATS - Python Automated Test Systems is a Python3 based test automation infrastructure.
It is developed as the next-generation Cisco mainstream automation infrastructure, is compatible to existing tooling &
infrastructure, and is officially endorsed by Cisco executive team.

The Lab

The files within this Github repository should be cloned to the local machine.

The objective of this lab is to:

• Become familiar with connecting to a testbed
• Leverage the Genie Ops libraries for retrieving operational data
• Explore the models and parsers leveraged by Genie Ops
• To become familiar with the Genie Parsergen library
• To start the journey on creating your own libraries

The Testbed

So as to provide the best experience in this lab the Genie Unicon Playback feature is being used. Playback allows for the interaction with a device without the device actually existing. If you wish to run the lab against a real or virtual device, then please modify the Topology file.

Pre-requisites

Users of this lab should have some familiarity with Python and basic concepts of
object-oriented programming.

To start please proceed to Step1

Credits

The code snippets and lab could not have been created without the excellent support and guidance from the Cisco ASG Genie Development team,
2018 Pioneer Award Winners.
In particular Siming Yuan, Jean-Benoit Aubin and Karim Mohamed. Could not have done without
support of Kevin Corbin either, and lastly, but by no means least, Hank Preston for the
Box Building and Vagrant plagiarism.
