Key Features

Book DescriptionSelenium WebDriver is a global leader in automated web testing. It empowers users to perform complex testing scenarios with its simple and powerful interface. This guide will provide you with all the skills you need to successfully create a functional Selenium test suite. Starting from the very beginning of the Selenium IDE, this book will show you how to transition into a real programing language such as Ruby or Java. You will quickly learn how to improve your code quality with refactoring and the skills needed to plan for the future development of your website to future-proof your test suite. With ample test examples running against a life-like e-commerce store and detailed step-by-step code review and explanations, you will be ready to test any challenge web developers might throw your way. This book is intended for anyone who wants to create a test suite that is easy to maintain by expanding your knowledge until you feel truly confident and comfortable with Selenium.What you will learn

Ratings and reviews

To begin with, in my opinion this book is for more experienced developers who are ready to take Selenium testing to the next level. I’ve been exposed to programming for about 2 years, starting with Ruby and currently learning some Java. While this book focuses primarily on using Ruby as the preferred language, have no doubt that Selenium can be used with Java as well. One of the strongest points of this technical book is that the author can convey advantages as well as disadvantages in a clear and concise manner. I have found that this helps greatly to see what is important and seeing possible downsides to a chosen path. Through showing us how software testing works from the first chapter, the author leads us through various examples and patterns in the current world of testing. It is up to date and includes relevant information now in 2014. In addition to explaining testing with the Selenium suite, the author also focuses on code reuse and refactoring, which will further help you grow as a programmer/developer. In Chapter 4, he also explains in depth test data and the various nuances associated with it. As the author states, you should be able to follow along the examples in this
