How to Test Same Endpoint Multiple Times with Postman Runner

I am trying to write an automated test Runner in Postman. I would like to test the same endpoint multiple times in a single run while changing the value of a parameter.

For example I would like to test

https://example.com/endpoint/
https://example.com/endpoint/
https://example.com/endpoint/

I can set a global variable on pass that in to run once with

let parameter = 'some value';
pm.globals.set("parameter", parameter);

How can I test an endpoint multiple times in one run?
