Of course.  But we already have that, thanks to a recent change by
Karl:

  ** Test your changes.

  Please test your changes before committing them or sending them to the
  list.  If possible, add a new test along with any bug fix or new
  functionality you commit (of course, some changes cannot be easily
  tested).

  Emacs uses ERT, Emacs Lisp Regression Testing, for testing.  See (info
  "(ert)") or https://www.gnu.org/software/emacs/manual/html_node/ert/
  for more information on writing and running tests.
