Should there also be a test for clicking Cancel?

Can you add a test for host-out-of-date as well? It should verify the display
name and that the upgrade interstitial is shown.

[kelvinp, 2015/03/03 21:57:54]

Done.  Unfortunately, the host out of date warning pop-up is not currently owned
by this class, so that part won't be verified here.
