Now create a folder named collection

Now, export collection and environment from postman. Save it to the “collection” folder you just created

Make sure, when saving the collection and environment files, there should not contain any space within the file name. You can fillup the space (if any) with underscore_

For example, postman collection file name is, customer_api_collection.json and environment file name is customer_api_env.json

Now give this command:

npx newman run .\collection\customer_api_collection.json -e .\collection\customer_api_env.json -n 1

This command means, newman will run your collection using the environment file for 1 time.

const newman = require('newman');{
    collection: require('./collection/customer_api_collection.json'), // pointing to local JSON file.
    environment: require('./collection/customer_api_env.json'), // pointing to local env file
    iterationCount: 1,
    reporters: 'htmlextra',
    reporter: {
        htmlextra: {
            export: './Reports/report.html', // If not specified, the file will be written to `newman/` in the current working directory.
}, function (err) {
    if (err) { throw err; }
    console.log('collection run complete!');

Now create a folder named Reports. If you do not create this folder, the report will be generate to a new folder named ‘newman’ in current working directory.
