Preparing Postman collections for Newman

As we have just seen, Newman is Postman's client tool, and in order to work, it needs the configuration of the collections, requests, and environments that we have created in Postman.

That's why, before running Newman, we will have to export Postman's collection and environments, and this export will serve as Newman's arguments. So, let's start exporting the DemoBook collection that we created in Postman.

Exporting the collection

The export of a Postman collection consists of obtaining a JSON file that contains all the settings of this collection and the requests that are inside it.

It is from this JSON file that Newman will be able to run the same API tests...
