Mastering Jenkins

By: jmcallister -, Jonathan McAllister

Overview of this book

With the software industry becoming more and more competitive, organizations are now integrating delivery automation and automated quality assurance practices into their business model. Jenkins represents a complete automation orchestration system, and can help converge once segregated groups into a cohesive product development and delivery team. By mastering the Jenkins platform and learning to architect and implement Continuous Integration, Continuous Delivery, and Continuous Deployment solutions, your organization can learn to outmanoeuvre and outpace the competition. This book will equip you with the best practices to implement advanced continuous delivery and deployment systems in Jenkins. The book begins with giving you high-level architectural fundamentals surrounding Jenkins and Continuous Integration. You will cover the different installation scenarios for Jenkins, and see how to install it as a service, as well as the advanced XML configurations. Then, you will proceed to learn more about the architecture and implementation of the Jenkins Master/Save node system, followed by creating and managing Jenkins build jobs effectively. Furthermore, you'll explore Jenkins as an automation orchestration system, followed by implementing advanced automated testing techniques. The final chapters describe in depth the common integrations to Jenkins from third-party tools such as Jira, Artifactory, Amazon EC2, and getting the most out of the Jenkins REST-based API. By the end of this book, you will have all the knowledge necessary to be the definitive resource for managing and implementing advanced Jenkins automation solutions for your organization.

Jenkins and Selenium Grid


If your organization is developing SaaS or web applications and has not been leveraging a Selenium Grid for automated testing you're really missing out on something special. A Selenium Grid provides a distributed automated testing solution that executes test cases in parallel. In this section of Mastering Jenking we will learn how to spin up a Selenium Grid, write basic unit tests, and capture the results in Jenkins. By learning this we can begin harnessing a Selenium Grid and help advocate for a scalable automated testing solution within Jenkins.

The architecture of a Selenium Grid is a single hub and multiple connected nodes, which is very similar in nature to a Jenkins master and slave node solution. The hub receives a testing manifest and distributes the tests for execution across the attached nodes. This distributed test architecture allows for multiple tests to execute in parallel, which reduces test execution time dramatically. To illustrate a Selenium Grid...
