amqp

xk6-amqp

A k6 extension for publishing and consuming messages from queues and exchanges. This project utilizes AMQP 0.9.1, the most common AMQP protocol in use today.

⚠ This project is not compatible with AMQP 1.0. A list of AMQP 1.0 brokers and other AMQP 1.0 resources may be found at github.com/xinchen10/awesome-amqp.

Build

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

• Go toolchain
• Git

Then:

1. Download xk6:

$ go install go.k6.io/xk6/cmd/xk6@latest

1. Build the k6 binary:

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

Development

To make development a little smoother, use the Makefile in the root folder. The default target will format your code, run tests, and create a k6 binary with your local code rather than from GitHub.

git clone [email protected]:grafana/xk6-amqp.git
cd xk6-amqp
make

Example

import Amqp from 'k6/x/amqp';
import Queue from 'k6/x/amqp/queue';

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'
  
  Queue.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",
    content_type: "text/plain"
    // exchange: '',
    // mandatory: false,
    // immediate: false,
    // headers: {
    //   'header-1': '',
    // },
  })

  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:
