Hello,

I am in despair. The attached source compiles fine, but gives:

$ bin/utf_dataset_loader_issue
Test setup error: test tree is empty

and I don't know why. It is based [Data-driven test cases parametrized
from the command line
<https://www.boost.org/doc/libs/1_73_0/libs/test/doc/html/boost_test/runtime_config/custom_command_line_arguments.html#boost_test.runtime_config.custom_command_line_arguments.data_driven_test_cases_parametri>](https://www.boost.org/doc/libs/1_73_0/libs/test/doc/html/boost_test/runtime_config/custom_command_line_arguments.html#boost_test.runtime_config.custom_command_line_arguments.data_driven_test_cases_parametri)
but reduced to pure API, no cli parse, file loading etc.

Any help is appreciated.
