The test can be asked to report its state, or it can do it itself.
Given that the test knows when it enters each phase, let's ask it to
report it.

Because the *state* is now reported, it's possible for a test to
finish (for instance by killing itself) without setting a valid (user
visible) status, such as "PASS", "FAIL", etc.
