Mastering Python Networking - Second Edition

By: Eric Chou

Overview of this book

Networks in your infrastructure set the foundation for how your application can be deployed, maintained, and serviced. Python is the ideal language for network engineers to explore tools that were previously available to systems engineers and application developers. In this second edition of Mastering Python Networking, you’ll embark on a Python-based journey to transition from traditional network engineers to network developers ready for the next-generation of networks. This book begins by reviewing the basics of Python and teaches you how Python can interact with both legacy and API-enabled network devices. As you make your way through the chapters, you will then learn to leverage high-level Python packages and frameworks to perform network engineering tasks for automation, monitoring, management, and enhanced security. In the concluding chapters, you will use Jenkins for continuous network integration as well as testing tools to verify your network. By the end of this book, you will be able to perform all networking tasks with ease using Python.

Pytest in Jenkins

Continuous-integration (CI) systems, such as Jenkins, are frequently used to launch tests after each of the code commits. This is one of the major benefits of using a CI system. Imagine that there is an invisible engineer who is always watching for any change in the network; upon detecting change, the engineer will faithfully test a bunch of functions to make sure that nothing breaks. Who wouldn't want that?

Let's look at an example of integrating pytest into the Jenkins tasks.

Jenkins integration

Before we can insert the test cases into our continuous integration, let's install some of the plugins that can help us visualize the operation. The two plugins we will install are build-name-setter...
