Overview of this book

Postman enables the exploration and testing of web APIs, helping testers and developers figure out how an API works. With Postman, you can create effective test automation for any APIs. If you want to put your knowledge of APIs to work quickly, this practical guide to using Postman will help you get started. The book provides a hands-on approach to learning the implementation and associated methodologies that will have you up and running with Postman in no time. Complete with step-by-step explanations of essential concepts, practical examples, and self-assessment questions, this book begins by taking you through the principles of effective API testing. A combination of theory coupled with real-world examples will help you learn how to use Postman to create well-designed, documented, and tested APIs. You'll then be able to try some hands-on projects that will teach you how to add test automation to an already existing API with Postman, and guide you in using Postman to create a well-designed API from scratch. By the end of this book, you'll be able to use Postman to set up and run API tests for any API that you are working with.

A few times in this book, I've told you that I think it is important for you to not just read this material, but to actually try it out. I've tried to show you examples that you can follow along with and given you challenges along the way to try out. I want to end this book with a large-scale, hands-on challenge. This challenge will pull together concepts from this entire book, so if you have been following along the entire time, you should have everything you need to be successful with it.

I know, however, that not everyone reads a book linearly from start to finish, and even for those of us that do, we may read it over the course of a few weeks, or perhaps even months, and so forget some of the stuff that we've learned along the way. I will be sure to include references to other chapters in this book that you can refer to along the way as we do this. Go back and re-read them whenever necessary.

I'm going to lay this...
