Performance Testing: Load, Stress, Spike, Soak and More
A functional test tells you whether your API gives the right answer. A performance test tells you whether it still gives that answer, fast enough, when many people use it at once.

A functional test tells you whether your API gives the right answer. A performance test tells you whether it still gives that answer, fast enough, when many people use it at once.
Design a performance test step by step (kind, workloads, load profile, targets), check it with a dry run, run it and watch it live, then find out why a run failed.
When a performance run finishes, Shift-Left API builds one report for it. The same report is what you see on screen, what you export as HTML, JSON or JUnit, what a share link shows, and what the project assistant reads.
