Jenkins automates building, testing, reporting, packaging, staging, deploying the application by using plugins. Jenkins offers a simple way to set up a continuous integration or continuous delivery environment for almost any combination of languages and source code repositories using pipelines, as well as automating other routine development tasks. While Jenkins doesn’t eliminate the need to create scripts for individual steps, it does give you a faster and more robust way to integrate your entire chain of build, test and deployment tools than you can easily build yourself.
