The Page Object Model (POM) is a design pattern used in Selenium to create object repositories for organizing and storing web elements, thereby reducing code redundancy and complexity and enhancing test script maintenance. By using POM, each web page is represented as a class containing web elements, which can be utilized by test scripts for various operations, offering clear separation between web element locators and their actions. This approach facilitates easier updates and maintenance, especially when the application's UI changes, and promotes code reusability. The Page Factory, an extension of POM, employs the @FindBy annotation and the initElements method to simplify and optimize the use of Page Objects, ensuring web elements are initialized before actions are performed, thus supporting better test automation practices.

Selenium is an open-source tool for automating web browser interactions, widely used for creating automated UI tests. It supports various programming languages like Java, Python, and Ruby, allowing users to simulate user interactions on websites, such as clicking links and filling forms. The two primary Selenium components are WebDriver, which is preferred for complex test scenarios, and Selenium IDE, a browser extension for creating and running tests with a graphical interface. Selenium tests rely on locating web elements using strategies like CSS selectors and XPath and employ different wait mechanisms, such as explicit and implicit waits, to handle asynchronous web page loading. Java is commonly used with Selenium due to its popularity and compatibility, and understanding core Java and object-oriented programming (OOP) concepts is essential for effective test automation. WebDriverManager aids in managing browser-specific drivers, simplifying setup and maintenance. An example test scenario involves automating Gmail’s login and account recovery process using Selenium WebDriver, with TestNG annotations organizing test execution.
