[BUG] [PATCH] Avoid interaction in test ~ob-tangle/detangle-false-positive~

[Evgenii Klimov <eugene.dev@lipklim.org>]

[-- Attachment #1: Type: text/plain, Size: 684 bytes --]

Test ~ob-tangle/detangle-false-positive~ asks for confirmation to kill
the buffer, connected to testing/examples/babel.org file, that is
modified during the couse of the test.

Way to reproduce the bug (from projects main dir):

#+BEGIN_SRC sh :dir (expand-file-name ".")
emacs -Q \
      -L lisp/ -L testing/ -L testing/lisp -l lisp/org.el \
      -l lisp/org-id.el -l testing/org-test.el -l testing/lisp/test-ob-tangle.el \
      --eval "(progn (org-reload) (setq org-confirm-babel-evaluate nil) \
      (org-babel-do-load-languages 'org-babel-load-languages \
      '((emacs-lisp . t) (shell . t) (org . t))))" \
      --eval '(ert "ob-tangle/detangle-false-positive")'
#+END_SRC
