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.

Integrating Newman into CI builds

Running your collection via the command line with Newman can help you quickly and easily run tests locally, but the real power of it comes in being able to automatically kick off and schedule runs. Many software companies now use CI systems that automate how builds and tests are continuously run every time a change is made to the code. Newman allows you to easily integrate into these CI build systems. This section will walk you through some general principles of using Newman in CI systems. I will then show you a specific example of applying those principles to integrate Newman into a Travis CI build.

General principles for using Newman in CI builds

There are many different CI systems and integrating with each one requires knowledge about how that system works. In broad terms, though, there are a few things you will need to do, regardless of the system you are working with:

  • You will need to make sure the build system has access to the...
