I agree with your "informal" summary of this checkpoint (I'll try to 
work this into the rationale). The problem with your proposed solution 
(using the term test harness) is that there may not be a test harness. 
We use the term "test execution process", and this process may or may 
not be automated. Only if it is will there be a "harness". Moreover, if 
there is, it will not be able to report status consistently unless the 
tests themselves do so.

Maybe we need to split this into two checkpoints: tests must report 
status consistently, and the test execution process, whether or not 
automated, must capture, summarize, pass on those statuses. This might 
be appropriate since typically tests and the execution process/harness 
will be defined/created by different people.
