Build a load test
Scenarios, thresholds and a report, from your own API surface.
Fill it in
If you have one.
The traffic shape you actually expect.
So a run fails rather than producing a chart.
Your prompt
Build a load test. [your what to simulate] Model the traffic SHAPE, not a flat rate. Real load arrives in bursts against a small number of hot endpoints with a long tail behind them, and a uniform test finds none of the problems a spike does. Use realistic think time and a realistic mix. A test hammering one endpoint with no pause measures that endpoint, not the system. Set thresholds so the run FAILS rather than producing a chart somebody interprets. p95 under a number, error rate under a number, and a checks pass rate. A load test without thresholds is a graph. Report percentiles, never averages. The mean latency of a system that is fine for 95% of users and terrible for the rest looks fine.
Use Build a load testOpens with everything above already filled in.
Why this works
Real load arrives in bursts against a few hot endpoints, so a uniform test finds none of the problems a spike does. This models the shape, sets thresholds so a run fails rather than producing a chart, and reports percentiles rather than means.
