Скачать или смотреть Hierarchy of Selenium Classes and Interfaces Explained

Welcome to my channel! In this comprehensive tutorial, I have explained the world of Selenium WebDriver interfaces and classes hierarchy, unraveling the structure and relationships that form the foundation of powerful test automation.

Selenium WebDriver is a popular and powerful tool for automating web browsers, providing a wide range of functionalities to interact with web elements, perform actions, and verify the behavior of web applications. Understanding the interfaces and classes hierarchy in Selenium WebDriver is essential for harnessing its full potential and designing robust automation frameworks.

In this video, we cover the following key points:

a. Interface hierarchy: The core interfaces in Selenium WebDriver, including WebDriver, SearchContext, and TakesScreenshot, and discuss their purpose and usage.
b. Class hierarchy: Class hierarchy of Selenium WebDriver, examining important classes like RemoteWebDriver, ChromeDriver, FirefoxDriver, and others, and understanding their functionalities.
c. Relationships and inheritance: The relationships and inheritance between the interfaces and classes in Selenium WebDriver, highlighting how they work together to provide a unified and extensible automation framework.
d. Key methods and functionalities: Essential methods and functionalities provided by Selenium WebDriver interfaces and classes, such as finding elements, interacting with elements, handling windows and frames, and performing advanced actions.

Also covered the below interview questions:

Q1. What is WebDriver driver = new ChromeDriver();
ChromeDriver(): Constructor (Constructor name and class name should be same which means it coming from ChromeDriver class only)
New: keyword in Java is used to create the object
Driver: reference variable, which can hold any kind of object like ChromeDriver/Firefox driver
WebDriver: Interface
Summary: Creating a ChromeDriver() instance (which will open the chrome browser) and keeping it inside WebDriver reference variable.

Q2. Can we give any other name instated of Driver?
WebDriver xyz = new ChromeDriver();

Q3. Can we write WebDriver driver = new WebDriver();
Interfaces can have abstract methods and variables. It cannot have a method body. That means Interface only have deceleration of method not their implementation. So, if we create object of that interface and call that method it compiles nothing as there is no code to compile.

By the end of this tutorial, you will have a comprehensive understanding of the Selenium WebDriver interfaces and classes hierarchy, equipping you with the knowledge to design efficient automation frameworks and perform advanced web automation tasks.
