It should actually say that 1 test cases being run, but no assertions
executed.

You have 2 choices.

1. Rewrite your test, so that it looks like:

...
BOOST_CHECK_MESSAGE( some_test, "message" );

2. Or you could write it like this:

....
If(some_test)
    BOOST_ERROR("message")
else
    BOOST_MESSAGE( "no error" );

I prefer first solution usually.
