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.

A glance at the JQuery library

Here, we will introduce a JavaScript library called JQuery. JQuery is one of the most popular JavaScript libraries available today. JQuery makes DOM traversal and manipulation simple. JQuery becomes more powerful when used with AJAX. AJAX stands for Asynchronous JavaScript and XML and is a web-development technique to send and receive data in the background without refreshing the web page. Many modern websites are being built using a combination of JQuery and AJAX.

JQuery can be used via the content delivery network (CDN) or downloaded as a JS file. For the example in this chapter, we will be using the CDN approach. We are using the 3.3.1 version of JQuery.

Cross-browser compatibility is a major advantage of JQuery over raw JavaScript. JQuery is extensible and has rich AJAX support.

We will be creating a sample JQuery application for pulling data...
