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.

Introducing JavascriptExecutor

JavascriptExecutor is is an interface in Selenium, which indicates that a WebDriver instance can execute raw JavaScript, providing access to the mechanism for doing that.

It has two methods:

  • The executeScript(String,Object...) object: Executes JavaScript code in the context of the currently selected frame or window. The script fragment provided will be executed as an anonymous function.
  • The executeAsyncScript(String, Object...) object: Executes an asynchronous JavaScript in the context of the currently selected frame or window. In contrast to executing synchronous JavaScript, scripts executed with this method must specifically send a signal when they are complete by invoking the associated callback function. This callback function is injected into the executed function as the last argument.
