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.

Introducing the WebDriverManager library

One constraint in Selenium automation is that we need to download the driver binary executable for Chrome, Firefox, and Internet Explorer. After downloading the executable files for Java, the absolute path of this executable file has to be set to JVM properties using System.setProperty. This was an overhead which has been removed with the introduction of a library called WebDriverManager.

Remember to use JDK 1.8 with this library. It won't work with JDK 1.7.

With this library, there is no need to download the individual binaries for the different browsers. Earlier, we had to manage the versions of the binaries manually. With this library, this gets handled automatically.
