Newman by Postman is an open source tool that developers and engineers can use to run and test Postman collections directly from the command line. The Newman CLI uses the same runtime as Postman native apps and maintains feature parity with Postman. This CLI tool can be used to run and test a collection once or every time a change is made to an API. The tool allows collections to be executed in the same manner as the collection runner in Postman.
