GMock seems to be discouraged, if not deprecated, for use in Chromium.

https://groups.google.com/a/chromium.org/forum/#!topic/chromium-dev/-KH_IP0rIWQ

While there does not appear to be a formal edict, I know that project leaders
seem to reject patches that use GMock.

So consider whether it's worth going against the grain here vs. just
implementing a simple manual mock.

[Sigurður Ásgeirsson, 2014/06/11 15:33:05]

Since Robert doesn't mind GMock, and since this is essentially mocking a clean
interface here (regrettably we don't declare interfaces pure virtual), I'd like
to leave it be.
