Overview of this book

Postman is an invaluable tool for exploration and testing of web APIs and helping testers and developers figure out how an API works. With Postman, you can create effective test automation for any APIs, and this guide will help you unleash its full potential. API Testing and Development with Postman is an invaluable resource for anyone who wants to create a good quality API, but isn't sure how to go about it. This guide will help you unleash the full potential of Postman’s test automation capabilities. 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. After you’ve familiarized yourself with the theory, you’ll move on to hands-on projects that will teach you how to add test automation to an existing API. You’ll also learn some of the new and powerful features that Postman has that can help you avoid introducing bugs. This second, fully updated edition features new chapters on workflow testing, creating and using mock servers, API security testing, and performance testing. The new and expanded information in this edition will help you future-proof your APIs. 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.

An example of automated API tests

I've laid out a challenge for you around creating test automation for a simple API. I hope you have worked through that challenge on your own and have a robust suite of tests that you can run against this API. In this section, I will show you one possible way that you could go about doing this. This is by no means the only way to do this and perhaps is not even the best possible way. If what you have looks quite different than this, that is no problem at all. There is a lot of benefit to seeing how other people approach their work, and so take this section as a place where you can see the work of someone else and perhaps even learn something from it.In this section, I will walk you through the process of designing the collection layout, and then I will show you the various tests that I made and how I set things up to share data between them and make them easy to run and maintain. I will also explain my thought process and why I decided to do things...
