description Artillery Overview

Artillery is an open source command-line tool designed for load testing web applications. It uses NodeJS to simulate multiple concurrent users accessing a website or API. This allows developers and testers to evaluate application performance under stress, identifying bottlenecks and ensuring stability. It integrates with tools like Web PageTest for comprehensive analysis and is particularly useful for those needing to assess responsiveness and scalability.

help Artillery FAQ

How do I write a load test script in Artillery?

Artillery test scripts are written in YAML or JavaScript, defining virtual users (scenarios), arrival rates, and HTTP requests. A basic script specifies a target URL, a 'flow' of requests each virtual user performs, and a load phase dictating how many users ramp up over what duration.

Can Artillery test WebSocket and gRPC endpoints, not just HTTP?

Yes, Artillery supports WebSocket, Server-Sent Events (SSE), and gRPC protocols in addition to standard HTTP and HTTPS testing. These engine types can be configured directly in your YAML test scenario to test real-time or streaming applications.

How does Artillery compare to k6 or JMeter for load testing?

Artillery is lighter-weight and more developer-friendly than Apache JMeter, with YAML-based scripting versus JMeter's GUI-driven XML format. Compared to k6, Artillery offers similar JavaScript-based scenarios but has been around longer with built-in support for more protocols, while k6 generally offers better performance at massive scale.

Can Artillery publish test metrics to CloudWatch or Datadog?

Yes, Artillery can publish real-time metrics to Datadog, AWS CloudWatch, and other monitoring platforms through its plugin system. This lets you correlate load test results with application performance metrics during the same test run.
