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.

BrowserMob Proxy Plugin


Another useful tool that is fully integrated with the Selenium WebDriver is called BrowserMob Proxy, and it is developed by Neustar, Inc. This free open source add-on allows users to capture performance data for web applications under test, identify network bottlenecks, modify the behavior of the browser under test, and change traffic patterns on the fly.

Users will set up this proxy server in their Selenium test environment and cast the WebDriver to it, allowing them to manipulate HTTP requests and responses during the test run. It uses the HTTP Archive (HAR) format to capture data.

Note

The BrowserMob Proxy Plugin is developed by (c) 2017 Neustar, Inc and is located at https://bmp.lightbody.net/.

Getting started

It is fairly easy to get started using the tool. You would first instantiate the proxy service in your WebDriver driver class code, pass that proxy capability to your driver, and turn the capture mode on to retrieve the HTTP responses and requests being sent...
