Here is a patch to fix this:

	Make it easier to abort a series of tests with C-g.

	* emacs-lisp/ert.el (ert-run-tests): Add "interactively" arg.  If
	interactively is true and a test was aborted then ask if the
	remaining tests should be aborted too.
	(ert-run-tests-batch, ert-run-tests-interactively): Pass in
	interactively arg.
