Load Testing
PronunciationLOHD TES-ting
Definition
Load testing is a performance testing process that simulates real-world user demand on a software system to measure its behavior under expected and peak conditions. It ensures the application remains stable and responsive when many users access it simultaneously.
Where you hear it
During sprint planning, infrastructure discussions, or when preparing for a major product release.
Examples
We need to perform load testing before the holiday season to ensure our servers don't crash.
The team ran a load test to see how many concurrent users the new API endpoint can handle.
Common mistake
Confusing load testing with stress testing; while load testing checks performance under expected limits, stress testing pushes the system beyond its limits to see how and when it fails.
