> I found it was because testDiskSpaceUtilizationLimit ran before 
> testCreateDirectories when running test, then directory "dirA" was created in 
> test function testDiskSpaceUtilizationLimit. When testCreateDirectories tried 
> to create "dirA" with specified permission, it found "dirA" has already been 
> there and it did nothing.
