I think the problem is a think-o on my part.
In the pseudo-code above, BOOST_ERROR is not executed unless "some
tests" is true.  So if the tests are OK, BOOST_ERROR is never hit.

I think the report of 0 (boost) tests being run is therefore accurate,
though confusing.

Does that sound right?

Is there a way to signal to boost that you are doing a test, without the
error?

I suppose, trivially, I could do
if (some tests)
  BOOST_ERROR("message");
else
  BOOST_CHECK(true);
