Running a request in Postman multiple times with different data only runs once

问题

I am new to Postman and running into a recurrent issue that I can’t figure out. I am trying to run the same request multiple times using an array of data established on the Pre-request script, however, when I go to the runner the request is only running once, rather than 3 times.

Pre-request script:

var uuids = pm.environment.get(“uuids”);

if(!uuids) {
uuids= [“1eb253c6-8784”, “d3fb3ab3-4c57”, “d3fb3ab3-4c78”];
}

var currentuuid = uuids.shift();
pm.environment.set(“uuid”, currentuuid);
pm.environment.set(“uuids”, uuids);

Tests:

var uuids = pm.environment.get(“uuids”);

if (uuids && uuids.length>0) {
postman.setNextRequest(myurl/?userid={{uuid}});
} else {
postman.setNextRequest();
}

I have looked over regarding documentation and I cannot find what is wrong with my code.

Thanks!

Pre-request script is not a good way to test api with different data. Better use Postman runner for the same.

First, prepare a request with postman with variable data. For e.g

Then click to the Runner tab

Prepare csv file with data

uuids
1eb253c6-8784
d3fb3ab3-4c57
d3fb3ab3-4c78

And provide as data file, and run the sample.

It will allow you run the same api, multiple times with different data types and can check test cases.
