Why not a const std::string reference?

Done.

[ahutter, 2013/01/19 02:07:16]

you should probably do an ASSERT_TRUE since you'll get a serious error if this
isn't here.  Also, no DCHECK's in tests only EXPECT_* or ASSERT_*.

ah, fixed! BTW, this was copied from

EXPECT is preferred unless ASSERT is necessary.
