Right now, the only way to know that a test run is finished is to either poll brasstacks, or to watch the machine the run is happening on.
It would be better if test runs would email when done. We could route emails to a "results only" mailing list, where we could proactively track them.
The best option might actually be if brasstacks itself could email us whenever a test run document is submitted (we'd turn this off for super-high-traffic like the crowd instance).
That approach would keep Mozmill from becoming a mail client, and us from having to implement email in a bunch of scripts.
Can you please file another bug for setting up an email alias first?
This has been fixed with Mozmill CI. E-mail notifications are sent to the email@example.com public list. See https://github.com/whimboo/mozmill-ci
