Newman
Newman is a command-line collection runner for Postman. It allows you to effortlessly run and test a Postman collection directly from the command line. It is built with extensibility in mind so that you can easily integrate it with your continuous integration servers and build systems.
Getting Started
To get started with the Newman setup, you need to have a node js version greater than 10. My current system has v16.9.1.
Installation
The easiest way to install Newman is using NPM. If nodejs is installed within the system, then it is most likely that you would have npm installed as well. To verify you have npm installed, run the command npm -v. To install Newman, run the command npm install -g newman . This helps running Newman from anywhere in the system.
Project Set-Up
Let's start implementing the API tests by creating the project directory structure. Inside the root directory of the project, I have created two directories app and report. Inside app there are two directories collections and runner.
Exporting a Collection From Postman
To export a collection from the postman, click on export from collection to the collection folder in the app directory of the project.
Setting Up Runner
To set up the runner, you will need to create a file called runner.js in the runner directory within the app directory. In the runner.js, we will need to give the path where the collections are present and the path where the report will be created.
Execution
To run the script, execute npm run apitest. This will run the collection using Newman and create the HTML report within the report directory.
