debug makes it possible to locally test your experiment without contacting Mechanical Turk servers. Type
debug to automatically launch your experiment in a browser window. The server must be running to debug your experiment. When debugging, the server feature that prevents participants from reloading the experiment is disabled, allowing you to make changes to the experiment on the fly and reload the debugging window to see the results.
-p flag to print a URL to use for debugging the experiment, without attempting to automatically launch a browser. This is particularly useful if your experiment server is running remotely.
-p flag to request a debug link:
[psiTurk server:on mode:sdbx #HITs:0]$ debug -p Here's your randomized debug link, feel free to request another: http://localhost:22362/ad?assignmentId=debugDKSAAE&hitId=debug2YW8RI&workerId=debugM1QUH4 [psiTurk server:on mode:sdbx #HITs:0]$
