Performance Testing

Definitions

1. A category of testing that evaluates a system's speed, scalability, and stability under expected and peak workloads. Subtypes include load testing, stress testing, and soak testing, commonly performed with tools like k6, JMeter, or Gatling.

   In plain English: Testing how well your system holds up under heavy use, to make sure it won't slow down or crash when lots of people use it at once.

   Example: "Performance testing showed the API handles 5,000 RPS fine but starts dropping connections at 8,000 — we need to add another replica before launch."
