After wrapped your cl-letf redefining function binding. Still failed on test.

Here is the new test code:

#+begin_src emacs-lisp
(ert-deftest test-org-fold/org-fold-display-inline-images ()
  "Test inline images displaying when cycling."
  ;; Mock `create-image' to work noninteractively.
  (cl-letf (((symbol-function 'create-image)
             (lambda (&rest _) `(image :type "dummy" :data "dummy"))))
    (let* ((org-cycle-inline-images-display t)
           (images-dir (expand-file-name "examples/images/" org-test-dir))
           (org-logo-image (expand-file-name "Org mode logo mono-color.png" 
images-dir)))
      ;; `org-cycle' -(state)-> `'children' display child inline images.

       (org-toggle-inline-images)
