Jenkins is a Continuous Integration (CI) server that provide Continuous Integration services for application development. Jenkins test and compile your code and if it finds everything is good then it allows to deploy the code. It is also beneficial in debugging and error fixing. It is written in Java. It is an open source means you can download and install on your PC without any cost. Let’s discuss some new concept in this Jenkins tutorial.

 What is Continuous Integration Tools?

Before we go dipper in Jenkins and know its features, let’s discuss CI.

Let’s imagine that software is ready and waiting for deployment on a server for testing. At first, a developer deploys the source code on the main repository. A Jenkins server checks the repository at regular intervals for changes. After the deployment, a Jenkins server checks the source code repo and detect the changes. Jenkins again compile and test the source code to find bugs and errors and then start again for the new build. If the build is successful then Jenkins ready to deploy this build on the test server and if Jenkins getting an error in build, it will inform about this to the mentioned team. You can also configure the script known as pipeline to create a new build. This action will complete in several steps.


After the successful testing Jenkins generate a feedback on code. If the new build is error-free and artifacts is valid, then Jenkins notify the developers about the successful build. Jenkins continuously check the main repository for changes on different intervals and provide update to developers about it.

Jenkins Continuous Integration

Before the Jenkins Continuous Integration, the process of a code testing is similar but Jenkins provide more flexibility. Let’s assume a developer complete the source code build and ready to deploy it on the test server but this process has many flaws.


With the above steps, software delivery process becomes slow and quality of software also went down. These processes increase the chances of dissatisfaction. With the Jenkins, a developer can continuously build and test source code.

 Jenkins Automation

Jenkins is the leading open-source automation server. It contains around 1400 plugins that support in the automation and all type of development task.

 Advantages of Jenkins

Jenkins Cucumber Plugin: - Cucumber is a tool that is used for testing. It was built on the concept of BDD framework. Where test is written in BDD (Behavior-driven-development) style. Jenkins provide an important plugin to integrate with Cucumber for execution.

It supports various types of computer languages.

It provides the reusability of code.

It acts as a bridge that connect business to technical language.

It allows writing a script without the knowledge of any code.

 Last word

Jenkins is very popular modern type automated testing tool that helps a developer to build, test and execute a code. It contains the rich set of plugins for testing. It reduces the software testing time and also save money.
