This book will be a lot of programming and describing the most popular design of patterns. In this book, I tried to focus more on the implementation concept of how and with what vision it is necessary to approach the creation of a test framework and an architecture I wrote my first automation testing framework back in 2014. This framework contained were a large number of architectural problems. But it is still in use today.This tells us that in 2014 there were well-known principles, approaches, and design patterns. These design patterns are absolutely the same to this day, and nothing has changed in more than 7 years.And it is about these basic principles and design patterns that I want to tell you in this book.
