Thank you. Some comments follow.

You need to add TINYCHANGE at the end of the commit message if you
haven't signed FSF papers yet.

Slightly better: 

  (forward-line)
  (forward-char (current-indentation))

You should use `org-test-with-temp-text' instead, and avoid "sh" as it
might not be active.  OTOH, emacs-lisp is always available:

--8<---------------cut here---------------start------------->8---
(should
 (org-test-with-temp-text
     "* Test
  #+<point>BEGIN_SRC emacs-lisp :file test.txt :cache yes
    (message \"text\")
  #+END_SRC

  #+RESULTS[c9828cf13461ca9ccb31e76ba4aee02ec6d7a4e7]:
  [[file:test.txt]]"
   (string= (concat default-directory "test.txt")
            (org-babel-execute-src-block))))
--8<---------------cut here---------------end--------------->8---
