This seems to be:

https://docutils.sourceforge.io/tools/editors/emacs/tests/ert-buffer.el

I'm not sure that this is useful for general use.  It has some
interesting ideas, but I'm not a big fan of the forms you seem to end up
with:

;;   (should (ert-equal-buffer '(insert "foo")
;;                             ; Insertion of "foo"...
;;   			       (concat ert-Buf-point-char ert-Buf-mark-char)
;;                             ; ...into an empty buffer with point and mark...
;;   			       (concat ert-Buf-mark-char "foo"
;;   				       ert-Buf-point-char)))
;;                             ; ...should result in a buffer containing "foo"
;;                             ; with point and mark moved appropriately.
