How to query unique request by graphql

Grafana k6

export scenario1 fundefault () {

mutation {
client(
id: “${id}”
)
}
};

I want to run a scenario with 10vus, 10iterations.
by first send id=1
and second send id=2
…
10th send id=10

please recommend me thank you!

Hi @Pamorn,

Right now it sounds to me like you might find execution API useful: to set id in mutation equal to VU’s index, execution.vu.idInTest. In case it is something else, could you please add what k6 script you tried and what exactly didn’t work? :slightly_smiling_face:

thank you for your reply.
you’ve got a point. but I can’t apply execution.vu.idInTest to my code could you pls take a look for me

type or paste code here
import { sleep } from 'k6';
import { SharedArray } from 'k6/data';
import { vu } from 'k6/execution';


const users = new SharedArray('Operators', function () {
  return JSON.parse(open('user2.json'));
});

export const options = {
    scenarios: {
      login: {
        executor: 'per-vu-iterations',
        vus: users.length,
        iterations: 2,
      },
    },
};



export default function  () {
  console.log(`InsertOperation: ${users[vu.idInTest - 1].name}`);
  sleep(1);
    const InsertOperation = `
    mutation {
        InsertOperation(
          OperationName: "a"${users[vu.idInTest - 1].name}"!"
        }
      }`
}

result here

    { "OperationName": "a04!" },

    { "OperationName": "a10!" }

I try to cut “${users[vu.idInTest - 1].name}” from “OperationName”${users[vu.idInTest - 1].name}“!” it’s work but that what I try to do.please point my error. :sweat_smile:

@Pamorn, with this JSON file, users would contain Objects with the key OperationName, not name. So using the following:

console.log(`InsertOperation: ${users[vu.idInTest - 1].OperationName}`);

should print a defined and expected result, e.g.:

INFO[0000] InsertOperation: a09!                         source=console
INFO[0000] InsertOperation: a04!                         source=console
INFO[0000] InsertOperation: a02!                         source=console
INFO[0000] InsertOperation: a03!                         source=console
INFO[0000] InsertOperation: a06!                         source=console
INFO[0000] InsertOperation: a01!                         source=console
INFO[0000] InsertOperation: a05!                         source=console
INFO[0000] InsertOperation: a08!                         source=console
INFO[0000] InsertOperation: a07!                         source=console
INFO[0000] InsertOperation: a10!                         source=console

I also think that InsertOperation can be a bit simplified, down to:

const InsertOperation = `
    mutation {
        InsertOperation(
          OperationName: ${users[vu.idInTest - 1].OperationName}
        }
      }`

Would these changes be sufficient for your use case?
