To get the most out of this book

This book is intended to equip you with skills that you can use immediately in your work as a tester or developer. If you want to get the most value that you can out of this book, put the things that you learn into practice as soon as you possibly can. Work through all the exercises in this book, but also try to take the ideas that you learn and put them into practice in the “real world” as well.

This book does not assume a lot of prior knowledge of APIs, or even development and testing principles. As long as you have a basic grasp of web technology and what software development looks like in general, you should be able to follow along with this book and pick up everything that you need. Some of the test scripts in Postman use Javascript, but you don’t need to know much about how that works in order to follow along, although a basic understanding would be helpful. There are examples and challenges throughout the book. They are an important part of the book and in order to get the most out of it, you should take the time to work through them.
