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.

I don't know about you, but I just love it when you can use a tool from the command line. Newman enables you to run Postman collections from the command line, and this opens up many possibilities. In this chapter, we have learned how to use Newman to run collections on the command line and how to leverage this to integrate API testing into build systems. Of course, to do this, you needed to learn how to install Newman, as well as Node.js, so that you can install it with npm.We then walked through some of the options for running Newman and saw how to run a collection in Newman, as well as how to include an environment and event data file for data-driven testing. We also saw some of the powerful reporting capabilities in Newman. This included the options for using the built-in reporters that come with it, as well as installing and using external reporters that others have shared. We walked through an example of using the htmlextra reporter. Then, we showed you how to install...
