Installing and Running Newman

Prerequisites

Newman is distributed as an npm package, so Node.js and npm must be installed on your machine before you can install it.

Installing Newman

CommandPurpose
npm install -g newmanInstalls Newman globally on the system
newman -vConfirms the installed version

Exporting a Collection

Before running with Newman, export the collection (and environment, if used) as JSON files from Postman using the three-dot menu next to the collection name.

Running a Collection

The basic command is newman run collection.json. Adding -e environment.json applies a specific environment, and results are printed directly in the terminal.

With Newman installed and running, the next step is generating detailed reports from those collection runs.
