Selenium Framework Design in Data-Driven Testing

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


Up to now, the WebDriver class has supported running browser and mobile tests from a local IDE of choice, and IntelliJ as a standard practice. In that context, browsers can be tested for Chrome, Firefox, Opera, IE/MS-Edge (if running Windows), and Safari (if running iOS). For mobile devices, the local choices are somewhat limited: Android phones and tablets for Linux and Windows environments, iPhone and iPad for iOS environments.

Now, what if there is a need for compatibility testing on, say, 10 different browser/platform combinations, and 10 different mobile device/platform combinations? It becomes a little cumbersome to try and test those using local development environments.

This is where the Selenium Grid Architecture comes in. The Selenium WebDriver class has an extended class called RemoteWebDriver that supports running the same set of tests remotely across platforms, browsers, and mobile devices. It uses the JSON wire protocol to communicate between the Selenium server...
