Performance and stress testing are crucial for Node.js applications to evaluate system behavior under normal and extreme traffic conditions. Performance testing assesses responsiveness and scalability under expected loads, while stress testing pushes systems beyond normal capacity to identify breaking points. These tests are essential for Node.js due to its asynchronous model, scalability limitations, and resource utilization patterns. The article compares three popular testing tools: AutoCannon (Node-based HTTP benchmarking), Artillery (cloud-native distributed testing), and k6 (developer-friendly with JavaScript scripting). A practical tutorial demonstrates setting up performance tests using AutoCannon with a simple Node.js server, including installation, test execution, and result analysis.

I have tried K6 in the past…
One question that’s always boggled me is how this test helps in real world
In the real world, multiple API endpoints are called one after another, usually with authentication.
So, there’s cookie parsing, either DB session lookup or jwt confirmation before the actual API logic
The actual API logic usually calls a DB as well
How can do a stress test that takes all this into account?
By stress testing a test endpoint that does all this with sample data?
