What is Newman? – Postman

Newman is a powerful command-line collection runner for Postman. It allows you to run and test a Postman collection directly from the command-line. Newman maintains feature parity with Postman and allows you to run collections the same way they are executed inside the collection runner in Postman.
Newman resides on both Github and at the NPM registry.
