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.

Multiple driver support


Occasionally, testing requires more than one client to be involved in a test. There will be cases where there are two browsers open at the same time, whether they are running the same application or not, and cases where there are one browser and one mobile device running simultaneously. This section will cover the requirements for running concurrent web and mobile drivers.

Dual WebDriver testing

The tricky part about running two or more WebDrivers at the same time is that you must keep track of which driver is getting the WebDriver events at any point in time. Otherwise, the current WebDriver, which is the last one that gets instantiated, gets all the events. How do we do that?

It's actually not that difficult. What needs to be done is this:

  1. Create the first WebDriver instance.
  2. Assign the first WebDriver instance to a variable.
  3. Create the second WebDriver instance.
  4. Assign the second WebDriver instance to a variable.
  5. Switch back and forth between the two drivers using the...
