nit: Consider moving these three lines into a RunMainLoopUntilDone() helper on
the test base?

[Rintaro Kuroiwa, 2015/05/21 21:53:29]

Oh, this 3 lines are duplicated in all tests. Maybe even call the method in 
Teardown then?

[Wez, 2015/05/21 22:10:45]

That's a good idea, yes.

[Rintaro Kuroiwa, 2015/05/22 01:04:04]

Done.

nit: Rename test, since capability has changed.
