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.

Unit tests in Jenkins through MSTest


As we mentioned earlier, unit testing provides developers with a formalized way to write code documentation, and encourages better coding practices. Unit testing is simply breaking down the functionality of a program into unit-testable behaviors, which can be repeatedly executed to verify the behavior of the code in response to standards, boundaries, and data inputs.

TDD, Test Driven Development or TFD, Test First Development, as we mentioned earlier, is a development technique where developers repeat a process of three activities, which are tightly interwoven.

  • Testing: Creating automated tests

  • Coding: Writing minimal code to just pass those tests

  • Design: Refactoring code to improve internal implementation without changing the external contract

At the time of writing, there are numerous Unit testing frameworks available. The most notable are MSTest, JUnit, CUnit, and NUnit, which are available for .NET, JAVA, Linux, and Windows respectively. In the next...
