[boost] boost test: first test organization examples using deprecated init_unit_test_suite?

according to this example, i should use init_unit_test_suite https://www.boost.org/doc/libs/1_75_0/libs/test/doc/html/boost_test/tests_or... but it seems that init_unit_test_suite function is deprecated (starting with 1.59) https://www.boost.org/doc/libs/1_75_0/libs/test/doc/html/boost_test/adv_scen... so its unclear to me if i should (still) use this deprecated function or go witht BOOST_AUTO_TEST_SUITE/BOOST_AUTO_TEST_CASE
