Installing Postman and Newman with npm

In this guide, we will walk through the steps to install Postman and Newman using npm (Node Package Manager) and how to run a Postman collection using Newman.

Prerequisites

• Node.js and npm installed on your system.

Install Postman

Postman provides a user-friendly graphical interface for creating and managing API requests and collections. To install Postman:

1. Open your terminal or command prompt.

2. Use npm to install the Postman command-line tool:
   

   npm install -g postman

1. Once the installation is complete, you can run Postman by typing postman in your terminal.

Install Newman

Newman is a command-line collection runner for Postman that allows you to run and automate Postman collections. To install Newman:

1. Open your terminal or command prompt.

2. Use npm to install Newman globally:
   

   npm install -g newman

1. Once the installation is complete, you can use Newman to run Postman collections from the command line.

Run a Postman Collection

Now that you have Postman and Newman installed, let's run a Postman collection using Newman.

1. Export a Postman collection from the Postman application if you haven't already. Save it as a JSON file (e.g., example_collection.json).

2. Open your terminal or command prompt.

3. Run the Postman collection using Newman:
   

   newman run example_collection.json

Replace example_collection.json with the name of your Postman collection file.

1. Newman will execute the requests in your collection and provide a summary of the results, including the number of requests run and their status.

What Next?

You've successfully installed Postman and Newman and used Newman to run a Postman collection from the command line. This is useful for automating API testing and integration into your CI/CD pipelines.
