Performance Test
ELI5 — The Vibe Check
Performance testing is measuring how FAST your app is under various conditions. Is the homepage loading in under 2 seconds? Does the search query take less than 100ms? It's like a stopwatch race for your code — does it meet the speed requirements?
Real Talk
Performance testing is an umbrella term covering load testing, stress testing, and benchmarking. It measures system metrics like response time, throughput, latency, and resource utilization to ensure they meet defined performance requirements.
When You'll Hear This
"Performance tests showed the product page takes 4 seconds — we need to optimize." / "Add performance tests to the CI pipeline to catch regressions."
