Understand OOPs / Java Concepts (Selenium Module Overview)

Why Java Matters for Selenium

Selenium WebDriver itself is just a library; test scripts are written in a programming language, most commonly Java. A solid grasp of Java — and especially Object-Oriented Programming (OOP) — is what allows a tester to build clean, reusable, maintainable automation code.

What This Module Recaps

• Core Java syntax: variables, data types, loops, and conditions.
• OOP concepts: classes, objects, inheritance, polymorphism, abstraction, and encapsulation.
• Java tools needed for Selenium: JDK, Eclipse, Maven, and TestNG.

Why This Foundation Matters

Everything that follows — Page Object Model, data-driven frameworks, hybrid frameworks — depends on comfortably writing and organizing Java classes, so this refresher ensures no gaps remain before diving into WebDriver itself.
