Introduction to Newman (CLI for Postman)
What Is Newman?
Newman is Postman's official command-line collection runner. It runs the same collections you build in the Postman app, but from a terminal, script, or CI/CD pipeline - without needing the GUI.
Why Use Newman?
| Reason | Benefit |
|---|---|
| Automation-friendly | Runs headlessly in scripts and pipelines |
| Same engine as Postman | Test behavior matches the Postman app exactly |
| Flexible reporting | Supports console, JSON, HTML, and JUnit reports |
How Newman Differs from the Postman App
Newman has no visual interface - it takes a collection (and optionally an environment file) as input and outputs results directly to the terminal or a report file, making it ideal for automated environments.
Now that you know what Newman is, let's walk through actually installing it and running your first collection from the command line.
