Register Now >We all know that Continuous Integration & Continuous Delivery are integral parts of DevOps, as they are used for integrating multiple stages of the methodology. There are many CI/CD tools in the market, but do you know that Jenkins, the Java-based open-source CI/CD tool, tops the popularity list? And it has always been the go-to option for DevOps professionals and beginners?
Jenkins is the oldest player in the CI/CD market, and it has more than 16,000 stars and 6,500 forks on GitHub. It also has huge community support with more than 1500 plugins to help professionals ship faster through their Jenkins Pipelines.
Jenkins is an open-source server that is written entirely in Java. It lets you execute a series of actions to achieve the continuous integration process in an automated fashion.
This CI server runs in servlet containers such as Apache Tomcat. Jenkins facilitates continuous integration and continuous delivery in software projects by automating parts related to build, test, and deployment. This makes it easy for developers to continuously work on improving the product by integrating changes to the project.
Jenkins automates the software builds in a continuous manner and lets the developers know about the errors at an early stage. A strong Jenkins community is one of the prime reasons for its popularity.
Some of the possible steps that can be performed using Jenkins are:

Before we dive into how Jenkins works, we must understand the architecture of Jenkins. These are the series of steps that outlines the interaction between different elements in Jenkins:
Here is the diagrammatic representation of the Jenkins architecture:

Do you know a well-defined Jenkins pipeline can help shorten production times and improve the quality of applications? It provides a definitive structure to your existing building process, committing, automation testing, and deployment. In this chapter, we will help you create your first Jenkins pipeline and run Selenium automation in Jenkins through an online Selenium Grid.
A pipeline is defined as a series of events or tasks which are interconnected in a particular order. In simple terms, the Jenkins pipeline is a set of modules or plugins which enable the implementation and integration of Continuous Delivery pipelines within Jenkins.
The Jenkins pipeline has an expandable automation system for building basic or complicated ‘template’ distribution pipelines via the Domain-specific language (DSL) used in the pipeline. There are four states of Continuous Delivery in Jenkins pipeline-

Today all the organizations are adopting DevOps as it promises to provide best practices starting right from planning, testing to deployment, and monitoring. CI/CD tools like Jenkins play an integral role in allowing organizations to implement DevOps. Jenkins integration with Selenium makes the entire process of Selenium test automation so much easier.
Before we look into Jenkins integration with Selenium, let us quickly define what is Selenium.
Selenium is an open source automation tool that has been widely used for testing web applications. It is easy to use, and it provides support forums, which makes it popular among the testing community. Selenium has four main components: Selenium IDE, Selenium RC, Selenium WebDriver, and Selenium Grid, designed and used for different purposes. Selenium provides cross-browser testing and parallel testing features, which allows the testers to execute their test cases in different operating systems and browsers, which ensures browser compatibility of the web application.
There are multiple ways to integrate Jenkins with Selenium WebDriver. In this chapter, we will take you through different ways to do so, which would help you implement based on your project requirements.

We all know that Jenkins is a popular tool for continuous integration, build management, and automation testing. But do you know that Maven is a popular build automation tool; widely used for Java projects? The combination of Selenium, Maven, Jenkins integration is the pinnacle of continuous integration and deployment.
As a part of automation testing, we’re sure your team comes up with numerous Selenium test automation scripts every other day. As Selenium itself is not used for Continuous integration, Selenium, Maven, and Jenkins integration are leveraged for build management and continuous integration. In this chapter, we look at the usage of Maven and Jenkins with Selenium.
Before we demonstrate the usage of Selenium Maven Jenkins integration, let’s take a look at the main advantages of using Maven and Jenkins with Selenium:

We all know that Jenkins is one of the most popular go-to DevOps automation tools for many software development teams. But if you want to get good results from this popular DevOps tool, you need to follow the best practices. With that in mind, we want to share some of Jenkin's best practices in this chapter.
