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.

API Testing and Development with Postman, Second Edition: API creation, testing, debugging, and management made easy

Summary

API specifications give you a lot of power in your testing. You can use them to keep documentation, tests, and even underlying code all in sync with each other. In this chapter, you learned how to use them to reduce the work in generating mocks and collections in Postman. You can also import API specs that others may have made, and use those in Postman. You have learned how to leverage an API specification to help you quickly create tests and mocks in Postman. In addition, you have learned how to use specifications in Postman to verify that the data being sent and received from a request is in the proper format. Taken as a whole, you have gained a lot of useful skills for using an API specification to help with testing and designing high-quality APIs. Creating and maintaining API specifications can be a bit of work, but they help with many aspects of API building. You are now able to create and use OASes in Postman!The ability to use API specifications will let you create APIs...
