Jenkins Tutorial

What is Jenkins?

I build the code for one of my projects and deployed it into a shared repository so that my team members can have regular access to it. The code deployment was not a one-time practice rather I had to integrate the code multiple times in the shared repository.  Once this is done any of the team members can verify the builds using automation techniques. So, JENKINS is a continuous integration (a practice) and development tool used by developers for integrating their codes so that they have run automation scripts.

Note - Automation testing is strictly related to CI it is typically implied.

Why should we learn Jenkins?

We always say that there can be multiple reasons behind the preferences for any particular skill; here in the case of Jenkins, the probable reasons can be multiple which can vary from person to person and also as per their experience.

• Good career growth – working with Jenkins make sure that you have a good understanding of coding and automation testing. This gives you confidence while searching for a job in other development/ testing profile tools.
• Team updation – using Jenkins the team can sync people and make them aware of the latest updates, this will reduce efficiency, especially slack integration. So Jenkins is definitely a tool with multiple crucial functionalities.

Application

• It is widely spread with more than 147,000 active installation
• It has a wide user segment over, I million.
• Jenkins is interlinked to over 1000 plugins for easy interaction, development & testing and deployment tools.

Example

Jenkins pipeline can serve a good demonstration for the readers, consider pipeline as a sequential activity which is interlinked together. It is a combination of plug-ins that supports integration & implementation. So when you are working on the development of applications than for each of these phases i.e. Build/Deploy/test and release the in-build plug-ins will lower your efforts while make you more focused on development and timeline.
