Piloting

Piloting before you launch: what Preview, Test run, and Try demo each check

Open Lab has three separate ways to run a study before participants do, and they check different things. Preview shows one task in its current editor state, Test run auto-plays it and reports mechanical failures, and Try demo walks the whole flow end to end. None saves data, and completion codes, link parameters, condition balance and quality signals appear only on a real participant link.
