Example

import exec from 'k6/execution';

import {
  AWSConfig,
  SQSClient,
} from 'http://jslib.k6.io/aws/0.14.0/sqs.js';

const awsConfig = new AWSConfig({
  region: __ENV.AWS_REGION,
  accessKeyId: __ENV.AWS_ACCESS_KEY_ID,
  secretAccessKey: __ENV.AWS_SECRET_ACCESS_KEY,
  sessionToken: __ENV.AWS_SESSION_TOKEN,
});

const sqs = new SQSClient(awsConfig);
const testQueue = 'http://sqs.us-east-1.amazonaws.com/000000000/test-queue';

export default async function () {
  // If our test queue does not exist, abort the execution.
  const queuesResponse = await sqs.listQueues();
  if (queuesResponse.urls.filter((q) => q === testQueue).length == 0) {
    exec.test.abort();
  }

  // Receive messages from the queue
  const messages = await sqs.receiveMessages(testQueue, {
    maxNumberOfMessages: 10,
    waitTimeSeconds: 2,
  });

  // Process received messages
  for (const message of messages) {
    console.log('Received message:', message.body);
    console.log('Message ID:', message.messageId);
    console.log('Receipt handle:', message.receiptHandle);
