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.

Understanding the Selenium Grid

Up until now, we have been executing Selenium code on our local machine. But that is not a very good idea. Eventually, we are going to run our framework from Jenkins and moreover, we will be running multiple instances of Chrome, Firefox, and Internet Explorer. Here's where Selenium Grid comes to our rescue.

Selenium Grid can be used to execute code on another machine or a virtual machine. It can also be used to execute code on multiple machines. Code is executed on multiple nodes due to which the total execution time is reduced.

Let's take a look at the Selenium Grid architecture.

Architecture of the Selenium Grid

To understand Selenium Grid, we need to understand the concept of hub...
