Overview of this book

The Selenium WebDriver 3.x Technology is an open source API available to test both Browser and Mobile applications. It is completely platform independent in that tests built for one browser or mobile device, will also work on all other browsers and mobile devices. Selenium supports all major development languages which allow it to be tied directly into the technology used to develop the applications. This guide will provide a step-by-step approach to designing and building a data-driven test framework using Selenium WebDriver, Java, and TestNG. The book starts off by introducing users to the Selenium Page Object Design Patterns and D.R.Y Approaches to Software Development. In doing so, it covers designing and building a Selenium WebDriver framework that supports both Browser and Mobile Devices. It will lead the user through a journey of architecting their own framework with a scalable driver class, Java utility classes, JSON Data Provider, Data-Driven Test Classes, and support for third party tools and plugins. Users will learn how to design and build a Selenium Grid from scratch to allow the framework to scale and support different browsers, mobile devices, versions, and platforms, and how they can leverage third party grids in the Cloud like SauceLabs. Other topics covered include designing abstract base and sub-classes, inheritance, dual-driver support, parallel testing, testing multi-branded applications, best practices for using locators, and data encapsulation. Finally, you will be presented with a sample fully-functional framework to get them up and running with the Selenium WebDriver for browser testing. By the end of the book, you will be able to design your own automation testing framework and perform data-driven testing with Selenium WebDriver.

Introduction

Java classes that are not Selenium page object classes, test classes, or data files, but support testing browser or mobile applications, can be considered utility classes. Most utility classes are static in nature, and use Java API methods that are not specific to any feature or test. They can include methods that operate on the browser or mobile device itself, but are not specific to the application running on them.

For example, the Selenium ExpectedConditions class has common methods to synchronize tests against actions occurring on a page, but it doesn't matter what the pages are, browser or mobile. Utilities can be built for file operations in reading, writing, or deleting files during tests. Test listener classes can be built, leveraging the TestNG TestListenerAdapter class, to log output to files and/or the console during test runs.

Other types of utilities that can be leveraged include image capture, JavaMail, third-party test listener and reporters, and JavaScript Executor...
