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.

Who this book is for

The first person I write for is myself. A lot of the stuff I talk about in this book is stuff I was learning myself a few years ago. API testing is a huge topic, and it can be intimidating to get started with, so I wrote this book primarily for those software testers who find themselves needing to test an API and not really knowing where to start. Throughout the book, I try not to assume too much in-depth programming knowledge, although an understanding of some of the most basic aspects of programming will certainly help with some sections of this book.

If you are working as a software tester and you are interested in expanding your skills into the API testing realm, this book is certainly for you. If you are a developer who is looking to enhance their skills in terms of understanding quality and testing, congratulations, you are setting yourself up for a successful career! You may be able to skim through some parts of this book, but you will certainly find a lot of helpful advice in here on how to design and write a test in a way that leads to good-quality APIs.
