Simple node function to run multiple postman collection in parallel

Running multiple Postman Collection in parallel

A known limitation of the Postman Collection Runner is that it can only execute collection in a consecutive way.

This project is a simple implementation of the solution explained in this StackOverflow conversation.

Recent changes

Added a new postman collection that call for a public api: https://openlibrary.org/dev/docs/api/lists so the project can be run right away after checkout.

Create your Postman Collection and corresponding tests

Here I needed to attack first /api/persons to get the list of persons ids.

And then /api/persons/:id for each person in the list.

To do that I used the postman.setNextRequest() tricks that specify the next request that will be executed in the collection run. And in each run I get the last personId and pop() it from the array in environment variables.

Export your collection and the environment variables

And save the files in a postman/ directory.

Create the new npm project

Simply run npm init -y and install the 3 dependencies: npm i async newman path newman-reporter-html

The script !

Specify the number of concurrent run, iterations inside each of them, the path for your postman collection and environment execute the script with npm start [NumberOfRuns] [NumberOfIterations] [Collection] [Environment] npm start 2 2 'postman/postman_collection_open_source.json' 'postman/localhost.postman_environment.json'
