Selenium WebDriver Quick Start Guide

By: Pinakin Chaubal

Overview of this book

Selenium WebDriver is a platform-independent API for automating the testing of both browser and mobile applications. It is also a core technology in many other browser automation tools, APIs, and frameworks. This book will guide you through the WebDriver APIs that are used in automation tests. Chapter by chapter, we will construct the building blocks of a page object model framework as you learn about the required Java and Selenium methods and terminology. The book starts with an introduction to the same-origin policy, cross-site scripting dangers, and the Document Object Model (DOM). Moving ahead, we'll learn about XPath, which allows us to select items on a page, and how to design a customized XPath. After that, we will be creating singleton patterns and drivers. Then you will learn about synchronization and handling pop-up windows. You will see how to create a factory for browsers and understand command design patterns applicable to this area. At the end of the book, we tie all this together by creating a framework and implementing multi-browser testing with Selenium Grid.

Let's next understand a very important class in Selenium: DesiredCapabilities. Before understanding the DesiredCapabilities class, knowing what Desired Capability means is necessary.

What is a Desired Capability?

All server implementations will rarely support every feature of WebDriver. It is advised that the client and server should use JSON objects with certain predefined properties when describing which features a user requests that has to be supported by a session. If a session cannot support a certain capability that is requested in the Desired Capabilities, a capabilities object is returned, which is read-only, and this object indicates the capabilities the session supports.
