Overview of this book

Selenium 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.

Summary

This concludes Selenium Design Patterns and Best Practices. The goal of this book was to demonstrate that Selenium testing is more than just clicking on links. To test a complicated application in a reliable and repeatable way requires a sophisticated Selenium test suite. Throughout this book, we touched upon some of the most difficult problems that I and people like myself have been encountering in the field of test automation. I hope that our collected knowledge will help save you weeks or months of frustration and confusion that I have personally experienced.

In conclusion, technical solutions provided in this book might not be the best solution in your individual case. However, I hope they will send you on the right path to something that fits perfectly for you. Improvising is a large part of this new field, so find out what works for you and share your accumulated knowledge with the Selenium community. Together, we can make test automation into an integral part of software development...
