--- Comment #8 from Nikolay Sivov bunglehead@gmail.com 2010-06-15 02:58:21 --- So it's simple to test. You need a stub ILockBytes implementation in test, that returns some path with ::Stat(), and then a check to IStorage::Stat() that returns the same path. Also it's nice to have a simple check to know that ILockBytes::Stat() called every time IStorage::Stat() called, so no internal caching or something like that happens.
