Habits that make performance test results trustworthy and useful — agree targets first, model real traffic, realistic data and environments, healthy load generators, measure the server, one change at a time, baselines, CI gates, safety, and a pre-report checklist.
How to learn performance testing in six milestones on a local practice app with deliberate bottlenecks — metrics, load, stress, spike, soak, CI gates and reporting — with answer keys and a final project.
Tasks with expected results for each of the six performance testing milestones on a local practice app — smoke, load at peak, stress and capacity, spike and recovery, soak and a memory leak, and a CI gate with a full report.
