⚠️ This is a proof of concept

As this is a proof of concept, it won't be supported by the k6 team. It may also break in the future as xk6 evolves. USE AT YOUR OWN RISK! Any issues with the tool should be raised here.

Build

To build a k6 binary with this extension, first ensure you have the prerequisites:

• Go toolchain
• Git

Then:

1. Download xk6:

$ go get github.com/k6io/xk6@latest

1. Build the binary:

$ xk6 build --with github.com/lxkuz/xk6-amqp@latest

Development

To make development a little smoother, you may run the build script provided in the root folder. It will create a k6 binary with your local code rather than from GitHub.

$ ./build.sh && ./k6 run my-test-script.js

Example

import Amqp from 'k6/x/amqp';
import Queues from 'k6/x/amqp/queues';

export default function () {
  console.log("K6 amqp extension enabled, version: " + Amqp.version)
  const url = "amqp://guest:guest@localhost:5672/"
  Amqp.start({
    connection_url: url
  })
  console.log("Connection opened: " + url)
  
  const queueName = 'K6 general'
  
  Queues.declare({
    name: queueName,
    // durable: false,
    // delete_when_unused: false,
    // exclusive: false,
    // no_wait: false,
    // args: null
  })

  console.log(queueName + " queue is ready")

  Amqp.publish({
    queue_name: queueName,
    body: "Ping from k6"
    // exchange: '',
    // mandatory: false,
    // immediate: false,
  })

  const listener = function(data) { console.log('received data: ' + data) }
  Amqp.listen({
    queue_name: queueName,
    listener: listener,
    // consumer: '',
    // auto_ack: true,
    // exclusive: false,
    // no_local: false,
    // no_wait: false,
    // args: null
  })
}

Result output:

$ ./k6 run script.js
