Unfortunately, there is no mean in ert to see how long a single test
runs. I often run expensive tests (well, I'm testing Tramp, filenotify,
autorevert :-) and it would help me to know the time for a single test
case run.

Maybe somebody could add it? I haven't the time just now; but if it
annoys me too much, I'll do it myself, later on, maybe.

This ticket might be a good place to remember this. Pls don't close it
after changing CONTRIBUTE.

Best regards, Michael.
