Many of the examples of this book will be based on real websites that most of us use every day. We are going to test websites like GitHub.com, StackOverlow.com, The Weather Channel, and PacktPub. That means that you will learn how to automate real websites using the latest technologies. However, this also means that some of the code examples might eventually fail. This could be due to network conditions, problems with the server, or a website redesign. However, our main aim is that you can learn the concepts and apply them to your own solutions besides these changes.
