This header should be first.

I don't think this rule applies to unittests does it?

Common misconception for old fartz who first read the style guide before the
change happened maybe 2 or 3 years ago:

http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Names_...
says: "In dir/foo.cc or dir/foo_test.cc, whose main purpose is to implement or
test the stuff in dir2/foo2.h, order your includes as follows:"

Done.

(And I'm not old!)

In Google years you are pretty old now :)
