One of the famous tools used for CI testing is Jenkins.

“Jenkins is an open source automation tool, which can be used to program all categories of tasks such as building, testing, and deploying software. Jenkins can be installed through native system packages, Docker, or even run standalone by any machine with the Java Run-time Environment installed.”

It helps to automate the non-human part of the software development life-cycle.

Jenkin pipeline is a package of plugins used for implementing the CI process in the delivery pipeline. Extensive set of tools are available with pipeline for modelling simple to complex delivery pipelines. It is a server based tool, which runs on Java servlet such as Apache Tomcat. It supports source control management such as AccuRev, CVS, Git, Mercurial, Subversion, RTC, Perforce and Clearcase.

There are a lot of plugins released for Jenkins to extend its use to projects, which are written in various languages besides Java.

Below is the flow diagram to explain how continuous integration testing can be done with Jenkins.
