RabbitStressTest

RabbitStressTest is a Node.js library designed to facilitate stress testing and message publishing within a RabbitMQ instance. It enables users to send messages to various bindings in RabbitMQ with different test scenarios.

Features

• Flexible Testing: Run various stress tests on RabbitMQ, including round-robin distribution, random distribution, extended-duration tests, and single-binding tests.
• Dynamic Configuration: Easily update RabbitMQ connection details, exchanges, and bindings within the test environment.
• Snapshot Functionality: Capture the state of the testing environment at specific moments, including connection information, exchanges, bindings, total messages sent, test duration, and message success rate.

Installation

npm install rabbitmq-stress-test

Usage

const RabbitStressTest = require('rabbitmq-stress-test');

// Define RabbitMQ connection details, exchanges, and bindings
const rabbitAddress = 'amqp://localhost';
const exchanges = [{...}, {...}, {...}];
const bindings = [{...}, {...}, {...}];
const message = {topic: "...", message: "..."}
const target = 1000;

// Create an instance of RabbitStressTest
const stressTest = new RabbitStressTest(rabbitAddress, exchanges, bindings, message, target);

// Prepare the tests before running
stressTest.prepTests();

// Run a stress test of your choice
stressTest.runTest('round-robin');

API

• connectToRabbitMQ(): Establishes a connection to RabbitMQ.
• publishMessage(exchangeName, key, msgObj): Publishes a message to a specified exchange.
• closeConnection(): Closes the connection to RabbitMQ.
• prepTests(): Prepares the tests by compiling exchanges and bindings and establishing a connection to RabbitMQ.
• runTest(type): Runs a stress test of the specified type.
• takeSnapshot(): Takes a snapshot of the current testing environment.
• updateRabbitStressTest(rabbitAddress, exchanges, bindings): Updates RabbitMQ connection details, exchanges, and bindings in the test environment.
• updateTarget(target): Updates the target number of messages to be sent.

Notes

• For extended-duration tests, the duration defaults to one hour. This can be adjusted if needed.
• Message distribution in "round-robin", "random", and "single-binding" tests continues until the target number of messages is reached.
