Based on the discussion in #53 , I just added the initial flow of CXX unittests for this repo, with providing two dummy UTs as placeholder to show the usage, feel free to add your own CXX unittests. @Superjomn @ptillet @ptillet , in this PR, I also configure the integration-tests.yml to add the unittest into github CI check. Thanks
