Artillery MQTT Engine - artillery-engine-mqtt

The Artillery MQTT Engine is a custom engine developed for Artillery, a modern, powerful, and flexible load testing toolkit. This engine enables Artillery to perform load tests using the MQTT (Message Queuing Telemetry Transport) protocol.

Introduction

The Artillery MQTT Engine, also known as artillery-engine-mqtt, is designed to extend the capabilities of Artillery by allowing it to simulate MQTT-based load tests. MQTT is a lightweight and efficient messaging protocol commonly used in IoT (Internet of Things) applications, but it can also be used for various other messaging scenarios.

Features

The main features of the artillery-engine-mqtt project include:

  • beforeScenario / afterScenario Hooks: You can define functions that will be executed before and after each scenario. This allows you to set up necessary resources before the scenario starts and clean up after the scenario completes.
  • Publish Messages: The engine allows you to publish MQTT messages to specified topics with custom payloads. This is crucial for simulating realistic messaging patterns in your load tests.
  • Looping with whileTrue: The engine supports a loop structure called whileTrue, which lets you repeat a set of actions while a specified condition remains true. This can be useful for creating dynamic and variable load patterns in your tests.

Usage

Configuration

In your Artillery script, you need to specify the artillery-engine-mqtt as the engine and provide the necessary MQTT configuration details. Here's an example configuration snippet:

yaml

config:
  target: "mqtt://mqtt.example.com:1883"
  engines:
    mqtt: {}
  mqtt:
    clean: true
    protocolVersion: 4
    auth:
      clientId: "my-client-id"
  processor: "./processor.js"
scenarios:
  - flow:
      - loop:
          - publish:
              topic: "sensor/data"
              payload:
                message: "hello"
            whileTrue: "continueLoop"

In this example, the target field specifies the MQTT broker's URL, and the engines section instructs Artillery to use the artillery-engine-mqtt for load testing.
