Newman Example Script for Postman Collection Execution

This Node.js script utilizes Newman to run a Postman collection, capturing and storing response data, while handling CSV data and optionally using SSL certificates.

Prerequisites

• Node.js installed on your machine. You can download it from here.
• Postman collection file (sample-collection.json) in the project directory.
• SSL certificates (test.crt, test.key, test.pem) for secure requests (optional).
• Iteration data in CSV format (TEST_DATA.csv).

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/your-repository.git

2. Install dependencies:

   npm install

Usage

1. Configure the script by setting the appropriate values in the newmanOptions object in script.js:

   • collection: Path or URL to the Postman collection JSON file.
   • sslClientCert, sslClientKey, sslClientPem: Paths to SSL certificate files (optional).
   • sslClientPassphrase: Passphrase for the SSL certificate (optional).
   • iterationData: Path to the CSV file containing iteration data.

2. Run the script:

   node .\save-response.js

Newman Run with CSV File and SSL Certificates

The Newman run is configured to:

• Use iteration data from a CSV file (TEST_DATA.csv) to provide dynamic inputs.
• Optionally perform requests with SSL certificates for secure communication.

Example CSV Data

Assuming the CSV file (TEST_DATA.csv) has the following structure:

Copy code
post_id
1
2
3
4
5

Sample Collection

The provided sample collection (sample-collection.json) contains a request named "SEND_SMS_SAMPLE" that uses the Postman variable {{post_id}} to dynamically replace the post ID in the request URL.

{
	"item": [
		{
			"name": "SEND_SMS_SAMPLE",
			"request": {
				"method": "GET",
				"header": [],
				"url": {
					"raw": "https://jsonplaceholder.typicode.com/posts/{{post_id}}",
					"protocol": "https",
					"host": ["jsonplaceholder", "typicode", "com"],
					"path": ["posts", "{{post_id}}"]
				}
			},
			"response": []
		}
	]
}

Output

• The script generates a CSV file (response.csv) with the response data for each request.
• The raw response data for the last request is stored in response.txt.

Notes

• If SSL certificates are not needed, you can remove the SSL-related configuration options (sslClientCert, sslClientKey, sslClientPem, sslClientPassphrase) from the newmanOptions object in script.js.
• Ensure that the Postman collection is correctly configured.
• Replace placeholder values in the newmanOptions object with your actual values.
