Stress Test
ELI5 — The Vibe Check
A stress test pushes your app BEYOND its limits to see when and how it breaks. A load test checks normal traffic. A stress test cranks it up to 11 until the app collapses, so you know its breaking point and how gracefully it fails.
Real Talk
Stress testing evaluates a system's behavior under extreme conditions that exceed normal operating capacity. The goal is to find the breaking point, observe failure modes, and verify the system recovers gracefully. It complements load testing by testing beyond expected limits.
