It is used to develop and test your software continuously hence making it simple and effortless for developers to integrate changes to the project thereby allowing them to come up with a better build. With many efficient technologies for integration, testing, and deployment, Jenkins enables you to deliver software continuously.
The process of software development is accelerated through automation, all thanks to Jenkins. It integrates processes development life-cycle of all types that includes building, documenting, testing, staging, packaging, deploying, analyzing, and more.
Some of the reasons for the increasing popularity of Jenkins are:
- It is a free, an open-source automated continuous integration tool
- It has a great community support

Jenkins Certifications
The Jenkins certification is a professional-level certification that proves that you possess the practical experience and skills needed to implement and utilize Jenkins. The two certifications that you can pursue are:
- Certified Jenkins Engineer (for expertise in Jenkins)
- Certified CloudBees Jenkins Engineer (for expertise in Jenkins and CloudBees core)
These certifications enable you to be recognized as expert programmers with integrity and expertise. The certification demonstrates that you have a good understanding of Continuous Integration and Continuous Deployment concepts as well as the best practices involved in DevOps.
The CJE exam comprises four different domains that include:
- Key concepts of Jenkins along with CI/CD – 27%
- Using Jenkins – 34%
- Deploying pipelined of both CI and CD – 23%
- Best practices that include CD as a code – 16%
You should learn the theoretical aspects of CI and CD such as the difference between both of them, types of tests, source code management, and more. You should also learn the installation and configurations of Jenkins and the basic concepts related to it. Other topics include processes required for configuring pipelines, building promotions, parameterizing tasks, triggering regular tasks, and elements of the Jenkins file.
The certification exam also focuses on removing vague terms, and also implementing alpha and beta test procedures in order to validate the feasibility of questions. Moreover, the exam emphasizes identifying any bugs and changing the format as per the modifications in Jenkins over time.
You should also study API commands and the method of manipulating the jobs by utilizing the Jenkins REST API. the most important topic to be learned is a multi-branch pipeline and source-code management. The topics related to these are Git and GitHub aspects including commit, branch, checkout, and pull request. Also, you are required to learn the ways of integrating Jenkins with SCM and working with multi-branch pipelines.
Next come the topics including unit tests, acceptance tests, integration tests, and other testing methodologies. Topics related to distributed builds that include fungible or replaceable agents, master/agent communication protocols, assignment of the stage to a node, etc are also to be studied.
