Short node program to test whether your fake-sqs supports long-polling

longpoll.js

const AWS = require('aws-sdk');

const sqsOptions = {
	endpoint: process.env.SQS_ENDPOINT || 'https://sqs.eu-west-1.amazonaws.com',
	region: process.env.AWS_REGION || 'eu-west-1',
}
const sqs = new AWS.SQS(sqsOptions);

const queueName = process.env.SQS_QUEUE_NAME || "SQS_QUEUE_NAME";

sqs.createQueue({QueueName: queueName}, function(err, resp) {
  if (err) {
    console.log('Could not create queue', err);
    return;
  }

  const params = {
    QueueUrl: resp.QueueUrl,
    WaitTimeSeconds: process.env.WAIT_TIME_SECONDS || 2,
  };

  const start = new Date();

  sqs.receiveMessage(params, function(err, data) {
    if (err) {
      console.log("Receive Error", err);
      return;
    }
    const now = new Date();
    console.log("Waiting for message took", now-start, 'ms');
  });

});

Usage: WAIT_TIME_SECONDS=10 SQS_ENDPOINT=http://localhost:4568 SQS_QUEUE_NAME=abc node longpoll.js
