Load Testing Patterns — quiz

A team load tests their e-commerce API at 200 concurrent users — their typical peak traffic. Response times and error rates are within SLA. What does this verify, and what does it NOT verify?

• It verifies everything relevant — peak load is the only scenario that matters for production readiness
• It verifies behaviour under expected load, but does not reveal the system's breaking point, how it handles sudden spikes, or whether it degrades over 8+ hours of sustained operation
• It verifies peak behaviour and implies the system handles all lower loads without needing to test them separately
• A load test at peak automatically encompasses stress and soak patterns since peak is the hardest scenario
