Testing how a system behaves under normal, heavy or extreme levels of use

Performance testing simulates 5,000 people checking out at once to see whether response times stay acceptable before a major sales event.
Think of it like…
Stress-testing a bridge with heavy lorries before opening day traffic arrives
