Question on Turns

Adventurer’s leave town and travel through a dark forest for three hours until they come to a cave. Is this a Turn even though no test has happened? I would think that those three hours could be taxing physically and emotionally as they may have anxiety from the possible danger.

Adventurer’s enter a cave and descend stairs. Then travel for a few hundred feat and come to an unlocked door. A character decides to open it and shine his torch inside.

Is this a Turn or not because no “tests” where given?

If they search the room but nothing is inside and no “test” is given, is it a Turn yet? I would assume at this point yes since a good amount of time has gone by (entering, going down the hall carefully, searching the room).

Thanks!

Turns only pass when tests are made. Turns are extremely elastic in the adventure phase.
