2 Mins read

Jenkins is the leading open-source Continuous Integration tool. It provides over 1000 plugins to support the creation and testing of almost any project. There are many companies, including Facebook, Netflix and Udemy, are reported to use Jenkins in their technology stack. Slack, Datadog, BrowserStack, Azure DevOps, and SonarQube are some of the popular tools that have integration with Jenkins.

Continuous Integration (CI) is a process where developers integrate their code on a regular basis. The code is regularly processed to a shared repository and a structure is triggered. As new code is processed, it is important that existing functionality is not broken and this is provided by Jenkins. The Jenkins tool is a popular open-source automation software used for Continuous Integration and Continuous Deployment process.

Jenkins compiles and runs functional tests and UI tests. It is also used for distribution and static analysis. Jenkins is an automation tool written in Java with built-in plugins for continuous integration tasks. It is used for constantly building and testing projects, making it easy to integrate changed code into it.

What are the main features of Jenkins and why use it?

It is built with the Java programming language and can be used on operating systems such as Windows, Ubuntu, Debian, Mac OS X, Red Hat, FreeBSD, Open BSD, Gentoo, Fedora, CentOS. It triggers the code build processes when new code is processed in the GIT repository. After the build is triggered, it shows the number of compiles that succeeded or failed, when the last build succeeded and failed, and preferably which parts of a pipeline succeeded or failed.

Jenkins distributes the code on the test server (or any desired server) and triggers automated tests. It produces test results that can be sent to the relevant teams by e-mail. It is the dominant tool with a large number of active installers and users worldwide. Therefore, there is a lot of support within the community. Jenkins can be used to automate the entire CI process.

How does Jenkins work?

A developer processes the code into the source code repository. The Jenkins tool detects changes in the source code repository as it periodically checks the repository. If there is a commit, Jenkins will start preparing a new build with new changes. If the build is successful, Jenkins deploys the build on the testing server.

If the compilation fails, the relevant team is notified. It gives a basic report on the success and failure of the build. After testing, Jenkins generates feedback. Creates a test report showing test results for development and quality control teams. As a result, the entire CI process is automated, resulting in higher efficiency and faster software delivery.

What are the advantages of Jenkins?

  • The Jenkins tool is widely used and therefore has a very strong community support. This means help is on hand for all problems and bottlenecks.
  • It provides over 1000 plugins to different applications in the DevOps process. This makes Jenkins highly extensible.
  • The best part is if you can’t find a plugin that fits your needs, you can write your own.
  • There are constantly incremental improvements.
  • It is an open-source, cross-platform tool.
  • Jenkins can generate test reports that can be viewed in the web UI.
  • It can automate the Continuous Integration (CI) and Continuous Development (CD) processes.
