As the test says it is checking a terminal.  So it was not only xvfb-run missing but
a terminal was needed.  Thus

   /usr/bin/xvfb-run --auto-servernum --server-num=20 -s "-screen 0 1024x768x24 -noreset" xterm  -e /bin/sh -c "R --no-save < $testfile"

finally solved the issue.

Kind regards

     Andreas.
