Selenium WebDriver Quick Start Guide

By: Pinakin Chaubal

Overview of this book

Selenium WebDriver is a platform-independent API for automating the testing of both browser and mobile applications. It is also a core technology in many other browser automation tools, APIs, and frameworks. This book will guide you through the WebDriver APIs that are used in automation tests. Chapter by chapter, we will construct the building blocks of a page object model framework as you learn about the required Java and Selenium methods and terminology. The book starts with an introduction to the same-origin policy, cross-site scripting dangers, and the Document Object Model (DOM). Moving ahead, we'll learn about XPath, which allows us to select items on a page, and how to design a customized XPath. After that, we will be creating singleton patterns and drivers. Then you will learn about synchronization and handling pop-up windows. You will see how to create a factory for browsers and understand command design patterns applicable to this area. At the end of the book, we tie all this together by creating a framework and implementing multi-browser testing with Selenium Grid.

The Command Pattern and Creating Components

Learning about Selenium without the knowledge of designing frameworks is not of much use. Frameworks help us with grouping components together and wiring them as per our needs. With a proper and structured framework, adding test cases is just a matter of updating the Excel sheet that has all of the test cases and test steps. It is just a matter of keeping track of the keys in the framework, which in our case is the test case ID.

In this chapter, we will cover the following topics:

  • Understanding the command design pattern
  • The project structure in Eclipse
  • Introducing the TestNG framework and TestNG.xml
  • Configuring nodes on the Selenium Grid for remote execution

The framework that we will be designing will be based on the command pattern. Hence, it will be a good idea to understand the command pattern first.
