This project is a Node.js utility to execute requests from a Postman collection concurrently. It reads the Postman collection JSON file, processes the requests (including handling placeholders and authentication), and executes them using the axios library. The tool provides detailed logs for each request's execution status (success or failure), tracks execution time, and generates a comprehensive summary report.

• Parse Postman collection JSON and extract requests and global information
• Replace placeholders (e.g., {{PLACEHOLDER}}) in the collection with environment variables
• Support for multiple authentication types: API Key, Bearer, Basic Auth
• Execute requests concurrently using Promise.allSettled for better performance
• Log detailed information for each request, including success/failure, execution time, and response data
• Generate a summary report with:
  • Total execution time
  • Successful/failed requests
  • Average time per request

Before you run the project, make sure you have the following installed:

• Node.js (v14 or higher)
• npm (comes with Node.js)

1. Clone the repository to your local machine:

   git clone https://github.com/your-username/postman-collection-runner.git

2. Navigate to the project directory:

   cd postman-collection-runner

3. Install the required dependencies:

   npm install

Make sure you have a Postman collection JSON file. If you don't have one, you can export a collection from Postman by following these steps:

• Open Postman.
• Go to your collection and click on the three dots (...).
• Select Export and choose the format Collection v2.1 (recommended).
• Save the JSON file.

Create a .env file in the root directory to define environment variables used in your Postman collection (e.g., replacing {{PLACEHOLDER}} values). Example:

API_KEY=your_api_key BASE_URL=https://api.example.com

Place your Postman collection JSON file in the postman-collections directory or update the COLLECTION_PATH variable in the index.js file to point to your file.

To run the utility, use the following command:

npm start

This will execute the requests in the collection concurrently and log the results in the terminal. You will also see a summary report at the end of the execution.

• Collection Path: Update the COLLECTION_PATH variable in the index.js file to point to your collection file.

• Authentication: The tool supports multiple authentication types (API Key, Bearer Token, Basic Auth). Make sure to include the appropriate auth information in your Postman collection.

The output will show detailed logs for each request and a summary at the end:

✅ [Request 1] - Success Time Taken: 123.45 ms Data: User 1 Details ❌ [Request 2] - Failed Time Taken: 98.23 ms Error: Network Error ✅ [Request 3] - Success Time Taken: 65.12 ms Data: User 2 Details Summary Report: Total Requests: 3 Successful Requests: 2 Failed Requests: 1 Total Execution Time: 350.23 ms Average Time per Request: 106.56 ms
