Jenkins is an automation server and free open-source continuous integration platform that tracks continuous integration and delivery. Java was used to write it.
It is referred to as an automated Continuous Delivery technology that makes it simple to develop and test software systems while incorporating modifications. In Jenkins, Groovy Scripting is used.
Additionally, it enables developers to review the post-build operations and check their code continually. When new code is introduced or modified, automation testers can utilize this to run their tests immediately.
