I might prefer declaring this as GetUsageAndQuotaFromQM or something and
accessing usage_ via the accessor usage(), mainly because in the current code it
is not really obvious where quota() is filled in the test code.

You can use test_helper_.GetLocalPathFromASCII() (to replace this together with
PlatformPath()).

If they're defined as member vars just to get deleted at TearDown() step, could
they be a vector like vector<base::PlatformFile> opened_files_?

[Dai Mikurube (NOT FULLTIME), 2011/06/14 06:29:41]

Ah, I found that they're not required at all.  They were used only for
base::TruncatePlatformFile().

I think they should be initialized at the test class's constructor-- or they
could just be replaced with a vector of PlatformFile as the above comment
(rather simpler).
