No, it's a test of whether it has "intelligence" (= a mind) AT ALL.

The test does not STATE this, it tests whether or not it is true that
you cannot tell them apart.

The penpal point is valid: What about our capacity to interact with real
objects in the world? This calls for a robot version of the Turing Test.
Also, the reason the Turing Test can't guarantee that the penpal has a
mind is that NOTHING can guarantee this -- because of the other-minds

We have no better or wrose basis for doubting it than we have for
doubting it in one another.
For an A, relate to the other-minds problem, reverse engineering, and
