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.

Using the Ashot API

The Ashot API provides the following features:

  • Takes a screenshot of an individual WebElement on different platforms (such as desktop browsers, iOS simulator, mobile Safari)
  • Decorates the screenshots
  • Provides screenshot comparison

Taking screenshots of individual WebElements is also possible with AShot.

AShot takes a screenshot in three steps:

  1. Captures a screenshot of the full page
  2. Finds the element's size and coordinates
  3. Adjusts the original screenshot by cropping

This way, AShot provides an image of the WebElement

To use AShot, add the dependency given here to pom.xml:


The following code helps to take a full-page screenshot:

public class TakeScreenShot {

public static void main...
