Overview of this book

In past few years, Agile software development has seen tremendous growth across the world. There is huge demand for software delivery solutions that are fast yet flexible to frequent amendments. As a result, CI and continuous delivery methodologies are gaining popularity. Jenkins’ core functionality and flexibility allows it to fit in a variety of environments and can help streamline the development process for all stakeholders. This book starts off by explaining the concepts of CI and its significance in the Agile world with a whole chapter dedicated to it. Next, you’ll learn to configure and set up Jenkins. You’ll gain a foothold in implementing CI and continuous delivery methods. We dive into the various features offered by Jenkins one by one exploiting them for CI. After that, you’ll find out how to use the built-in pipeline feature of Jenkins. You’ll see how to integrate Jenkins with code analysis tools and test automation tools in order to achieve continuous delivery. Next, you’ll be introduced to continuous deployment and learn to achieve it using Jenkins. Through this book’s wealth of best practices and real-world tips, you'll discover how easy it is to implement a CI service with Jenkins.

The Jenkins pipeline to poll the feature branch


In the following section, we will see how to create both the Jenkins jobs that are part of the pipeline to poll the feature branch. This pipeline contains two Jenkins jobs.

Creating a Jenkins job to poll, build, and unit test code on the feature1 branch

The first Jenkins job from the pipeline to poll the feature branch does the following tasks:

  • It polls the feature branch for changes at regular intervals

  • It performs a build on the modified code

  • It executes unit tests

Let's start creating the first Jenkins job. I assume you are logged in to Jenkins as an admin and have privileges to create and modify jobs. The steps are as follows:

  1. From the Jenkins Dashboard, click on the New Item link.

  2. Name your new Jenkins job Poll_Build_UnitTest_Feature1_Branch.

  3. Select the type of job as Freestyle project and click on OK to proceed.

  4. Add a meaningful description about the job in the Description section.
