I think you may need to change method_missing here to:

      def method_missing(method, *args, **kwargs, &blk)
        test_unit_class.send(method, *args, **kwargs, &blk)
      end

We had to monkeypatch this in our application as Ruby 3 no longer supports passing keyword arguments as regular arguments or a Hash.
