As a Roblox developer, it is currently impossible to debug in Team Test mode.
If Roblox is able to address this issue, it would improve my development experience because in my case, debugging in multi-user mode is FUNDAMENTAL, since the game has many variations when there are multiple users, and currently there is no way to do that other than stuffing the whole script with countless prints and repeating extensively testing until you understand what is going on.
What tools or widgets are you using when you say ādebuggingā? I only use the console because everything else is too complicated, or there is no documentation that I could find for it. Pretty sure you can use the console anywhere in roblox. Are you talking about using breakpoints?
Debugging is using breakpoints, this is so industry standard that they are one in the same. OP has already mentioned that print debugging is undesirable.
Did not realize team test cannot be debugged, and yet Roblox wants to push team create as default.
Oh. Well I donāt see how roblox could implement breakpoints in a team test. Breakpoints pause the game for debugging when theyāre reached, but how should that react with multiple players? No idea. I think that @rogeriodec_games should explain what the behavior of breakpoints in a team test would be like.
I never liked breakpoints. We didnāt get along.
If you ever have REALLY complex logic, you REALLY need breakpoints.
And, as I said in the OP, my logic varies when there are several players online, so breakpoints would be INDISPENSABLE in Team Test.
By debugging do you mean debugging on the server or client? I donāt think that debugging on the server is possible yet and this is probably why they donāt have the feature.
It seems you donāt know how the studio debugger works. Currently is possible to debug both server and client, but only for a single user. Iām asking to have exactly the same, but for multi-user scenario, with Team Test.
I was referring to the team test server. The playtesting server is referred to as a virtual server.
Is it still possible to do so?
AFAIK, no. All debugging comes down to the virtual server emulated in Studio. I think Team Test should also emulate a virtual server. And as such, it should also allow debugging (unless Team Test is a simple Roblox Player emulation (using all of its original engine). If so, I believe it is impossible for this my request to be done).
Team test uses an actual Roblox server for hosting
How do you know. Where is it documented?
When you attempt to publish you receive āsent message to server to publishā, you can also check the connection strength to the server on the top-right.
In this case, from what youāre saying, itās practically a confirmation that Team Test emulates the Roblox Player engine instead of the virtual server that is used in the single player test, which is a shame, because in this case it will be impossible to debug in Team Test.
Try doing a test server session, then go to the placeās page at check the servers tab. You can see your team test server there but you canāt join it via a normal Roblox client.
Iām testing a feature in my game that only runs with multiple players and I want to see how the workspace changes within a few 1 second waits to explore all instances for as long as I want, so break points are absolutely crucial to further development. It is stupid you canāt debug in test mode and I would start a petition to Roblox to change that if I had the following. Thanks for uploading this topic so that I know Iām not alone 
Old topic, but I hate to point out that itās called āTeam Testā, not āTeam Debugā
