Groovy Power Up: Master Groovy Scripting Online Training

Module Description:

This module serves as an introduction to Groovy scripting, a powerful and versatile scripting language that runs on the Java Virtual Machine (JVM). Participants will learn the basics of Groovy syntax, data types, control structures, and object-oriented programming concepts. Additionally, they will explore practical applications of Groovy scripting, including scripting automation tasks, writing custom scripts for Jenkins pipelines, and extending existing Java applications with Groovy.

Module Objectives:

• Understand the fundamentals of Groovy scripting language.
• Learn Groovy syntax, data types, and control structures.
• Explore object-oriented programming concepts in Groovy.
• Apply Groovy scripting for automation tasks and Jenkins pipelines.
• Gain insights into extending Java applications with Groovy scripts.
