Quote: Also remember that automation is not always the only way to execute a load test. I've had recent discussions with my teams and mentioned "go find 25 people and perform a manual load test"....will the timings be totally accurate. Nope. Is it a good way to get feedback back to R&D and PM...absolutely.
I personally disagree very strongly with this approach. In fact, the lowlight of my performance testing career was hearing an "everyone please login to start the performance test" over the intercom at a previous job.
Unless your goal is to waste resources and give misleading information, then I don't think there is really ever a place for that.
1 guy knocking out a test script is orders of magnitude more accurate, simpler, reproducible, and faster, in nearly every thinkable circumstance.
Having 25 (or 50, 100, 1000) engineers stop what they are doing, context switch mentally, follow some menial test plan, finish, and get back to work, is a *very* expensive task. The amount of work lost each time you do one of those could probably pay for your automation many times over.
