Prerequisites

• Basic Understanding of Java:
  Familiarity with Java programming, including syntax, object-oriented concepts, and basic programming constructs like loops, conditional statements, and exception handling.

• Introduction to Selenium:
  A basic understanding of Selenium WebDriver is recommended, as TestNG is often used in conjunction with Selenium for test automation.

• Basic Knowledge of IDEs:
  Experience writing and running Java code using an Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse.

• Familiarity with Testing Concepts:
  A foundational knowledge of software testing concepts, such as test cases, assertions, test suites, and testing lifecycle.

• Basic XML Knowledge:
  Some exposure to XML file structures, such as TestNG configuration files, are written in XML format.

• Java Development Kit (JDK) Setup:
  Ensure the JDK is installed and configured on your machine, and understand setting up environment variables (like JAVA_HOME).

• Maven Basics (Optional):
  Familiarity with Maven or similar build tools helps manage dependencies and integrate TestNG with larger projects.

• Command Line Basics (Optional):
  Basic command-line usage for running test cases, managing files, and executing builds.
