I think the typical pattern is that stub classes live in the *_unittest.cc file
that uses them. Then you don't need *_stub.h either. Is this used in multiple
places?

Ditto for the other stub files.

agreed that you can do this if these are only used in a single test file. if
not, you can probably just inline the implementation in the .h file and get rid
of this one (at least, i wouldn't care much about
http://www.chromium.org/developers/coding-style/cpp-dos-and-donts#TOC-Stop-in...
for a stub file...)

Sure.
Done.
