Performance testing is a crucial step in ensuring that your application can handle real-world traffic, perform well under heavy load, and recover from unexpected spikes or prolonged usage. Grafana K6 is a modern, open-source load testing tool that can be used to simulate and measure the performance of web applications, APIs, and services under various conditions.
In this article, we’ll walk through the implementation of load testing, stress testing, spike testing, and soak testing using Grafana K6 in a Node.js environment. We will also integrate Grafana to visualize the metrics and performance results.
