You're close. The noweb ref should be a named src block which is
executed, not expanded, so, (note the named shell source block and the
parens in the noweb reference):

#+name: testing
#+BEGIN_SRC sh :results raw
echo "["
ls *.org | sed 's/$/;/'
echo "]"
#+END_SRC

#+BEGIN_SRC ocaml :noweb yes
let x =
<<testing()>>
in x
#+END_SRC
