Function tests

<!-- description --> @brief Used to execute the actual checks. We put the checks in this function so that we can validate the tests both at compile-time and at run-time. If a bsl::ut_check fails, the tests will either fail fast at run-time, or will produce a compile-time error. <!-- inputs/outputs --> @return Always returns bsl::exit_success.
