Artillery - modern, powerful, easy-to-use load-testing framework

Artillery At A Glance

• Load-test HTTP, WebSocket and Socket.io applications
• Specify scenarios to simulate complex virtual user behavior (perfect for transactional APIs, ecommerce applications etc)
• Detailed performance metrics (latency, requests per second, concurrency, throughput)
• Dynamic payloads from external CSV files (e.g. usernames/passwords for making auth requests)
• Scriptable with JS
• HTML reports
• Nice CLI
• Good performance
• statsd support out of the box for real-time reporting (integrate with Datadog, Librato, InfluxDB etc)

Artillery has a strong focus on developer happiness & ease of use, and a batteries-included philosophy.

Artillery's goal is to help developers build faster, more resilient and more scalable applications.

Use Cases

• Benchmark the performance of your API or microservice as you're building it
• Ensure new code does not introduce performance regressions
• Test your code for memory leaks
• Benchmark dependencies (libraries, frameworks, external services) to get a feel for their performance characteristics before you integrate
• Run load-tests before you launch to ensure your application can meet projected demand

Quickstart

Install

Artillery is available via npm

$ npm install -g artillery

Run A Quick Test

$ artillery quick -d 30 -r 5 -n 20 http://127.0.0.1:3000/test

This will run a test for 30 seconds, with 5 new virtual users created every second, with each user sending 5 a GET requests to http://127.0.0.1:3000/test.

Run With A More Complex Scenario

$ artillery run hello.json

Where hello.json is your tests script that contains something like:

(NB: test scripts can be written as YAML too)

{
  "config": {
      "target": "http://127.0.0.1:3000",
      "phases": [
        { "duration": 120, "arrivalRate": 10 }
      ],
      "defaults": {
        "headers": {
          "content-type": "application/json",
          "x-my-service-auth": "987401838271002188298567"
        }
      }
  },
  "scenarios": [
    {
      "flow": [
        { "get": {"url": "/test"}},
        { "think": 1 },
        { "post": {"url": "/test", "json": { "name": "hassy" }}}
      ]
    }
  ]
}

This will run a test for 2 minutes, with 10 virtual users created every second, each of which will send a GET and a POST request with a pause of 1 second in between. Each request will include two custom headers (Content-Type and X-My-Service-Auth).

Create A HTML Report

Once the test completes, you can create a graphical report from the JSON stats produced by artillery run with: artillery report <report_xxxxx.json>

These are self-contained HTML files that can be easily shared via email or Dropbox for example.
