I'm guessing from what you say that the self test just stopped in the
middle - at a certain point it seemed to go away, and I assumed that
was a sign of success. Perhaps in fact it was a sign of failure. There was
no explicit announcement of what to expect next. Since it didn't tell me
what to expect, the absence of evidence was not evidence of absence.

Yes, a test room would need to include some synthetic sound and
vision, or a delayed echo of sound and vision.
