Overview of this book

Selenium WebDriver 3.x is an open source API for testing both browser and mobile applications. With the help of this book, you can build a solid foundation and learn to easily perform end-to-end testing on web and mobile browsers. You'll begin by focusing on the Selenium Page Object Model for software development. You'll architect your own framework with a scalable driver class, Java utility classes, and support for third-party tools and plugins. Next, you'll design and build a Selenium Grid from scratch to enable the framework to scale and support different browsers, mobile devices, and platforms. You'll also strategize and handle a rich web UI using the advanced WebDriver API, and learn techniques to tackle real-time challenges in WebDriver. Later chapters will guide you through performing different types of testing, such as cross-browser testing, load testing, and mobile testing. Finally, you will be introduced to data-driven testing, using TestNG to create your own automation framework. By the end of this Learning Path, you'll be able to design your own automation testing framework and perform data-driven testing with Selenium WebDriver. This Learning Path includes content from the following Packt books: • Selenium WebDriver 3 Practical Guide - Second Edition by Unmesh Gundecha • Selenium Framework Design in Data-Driven Testing by Carl Cocchiaro

The image capture class

Another important library to include in the framework is the image capture class. It is used by the test listener, reporter, and test classes to take screenshots of the browser or mobile screens when exceptions occur. There are various methods that can be built to capture the image of the entire screen, an individual WebElement or MobileElement, or to compare the images. Each method will be outlined here:

The image capture methods were developed by Unmesh Gundecha, and published by Packt Publishing in the reference book Selenium Testing Tools Cookbook - Second Edition. The book is available at https://www.packtpub.com/web-development/selenium-testing-tools-cookbook-second-edition.
