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.

Why is test automation required?

Let's get started by understanding why test automation is needed. Today's agile world needs quick feedback on the code's quality. The developers check-in application code in a source code repository like GitHub. It is imperative that these changes be tested, and the best way to do so is through automation. A test-automation suite can eliminate the mundane work of manual regression testing and can be helpful in finding bugs earlier, thus reducing manual testing time. It can be configured to run at a particular time in the day.

A cut-off time should be provided to the developers, such as 6 P.M. in the evening, by which time they should check in code, get the application build done, and the application deployed to a server like Apache Tomcat. The automation suite may be scheduled to run at 7 P.M. daily. Jenkins is a tool that's used for continuous integration, and so can be used for this purpose.

Advantages of test automation

Advantages of test automation include reducing the burden on the testers doing the manual execution so that they can focus on the functional aspects of the application. Generally, a smoke, sanity, regression test suite is created for this purpose. The advantage of having automatic triggering through Jenkins is that it facilitates test execution in an unattended mode.
