Sans has good, but not perfect, knowledge of Frisk’s journey.

Remember that if Frisk died before the MTT dinner, and used his own ability to load his save and rewind time, Sans is actually surprised at Frisk’s reaction to the claim that he never died once.

But if it’s true that Frisk hadn’t died, Sans winks, and chalks it up to his... own skills.

The Anomaly is probably Chara. Who, again, is also The Player, who’s somehow gained control of Frisk.

Frisk does have a mind of his own. We can’t hear what he says to others, but he’s the one who tells Asriel that his real name is Frisk. Even if we, The Anomly, can control what Frisk does, Frisk is still a real person with a past.

And Sans knows about this. In fact... I don’t think he says “Frisk” even once in the ending phone calls. I think he’s talking directly to The Player.

And Sans has no idea how The Player is going to act. So they have to be tested.
