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.

Building a Scalable Selenium Test Driver Class for Web and Mobile Applications

In this chapter, we will cover designing and building the Java test driver class required to create and use the Selenium WebDriver API and AppiumDriver API for automated testing. The driver class is the central location for all aspects and preferences of the browser and mobile devices, platforms and versions to run on, support for multithreading, support for the Selenium Grid Architecture, and customization of the driver. This chapter will cover the following topics:

Introduction
The singleton driver class
Using preferences to support browsers and platforms
Using preferences to support mobile device simulators, emulators, and real devices
Multithreading support for use in parallel and distributed testing
Passing optional arguments and parameters to the driver
Selenium Grid Architecture support using the RemoteWebDriver and AppiumDriver classes
Third-party grid architecture support, including the Sauce Labs Test Cloud
Using property files to select browsers, devices, versions, platforms, languages, and so on
