Why would you want to use an inheritance (just a general question)?

To be frank with you I do not see anything particular generic in the code 
below and don't really understand what you are trying to do. Could you 
please give some more detailes. Than I probably be able to give some 
recommendations.

You don't need secont using statement. Both namespaces are synonims.

That's invalid

I recommend you to avoid init_unit_test_suite and use BOOST_AUTO_TEST_CASE 
instead.
