> 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.
