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


In the last chapter, data-driven test classes and methods were designed and built to demonstrate how to use TestNG annotations and parameters to design and build test, setup, and teardown methods. In this chapter, we will dive further into the topic of test data. From what we have learned, encapsulating data into central locations and breaking it out from the test methods and page object classes is an important standard to follow.

What we need to understand about test methods versus test data is this: test methods should be small engines that perform a task, can take any variation of data, and that can test positive, negative, boundary, and limits of a feature. There is always an input and a verifiable output to a test. If users follow this rule, then simple "keyword" templates can also be built on top of the framework that allow users to extend test coverage by adding "sets" of data to run through the engines.

So, when designing the test framework for a development environment...
