} from 'https://jslib.k6.io/aws/0.11.0/s3.js';


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


const s3 = new S3Client(awsConfig);
const testBucketName = 'test-jslib-aws';
const testFileKey = 'bonjour.txt';


export default async function () {
  const objects = await s3.listObjects(testBucketName);


  // If our test object does not exist, abort the execution.
  if (objects.filter((o) => o.key === testFileKey).length == 0) {
    exec.test.abort();
  }


  // Let's download our test object and print its content
  const object = await s3.getObject(testBucketName, testFileKey);
  console.log(JSON.stringify(object));
}
