Thanks for your feedback.

For chdir case i just use Petr's below suggestion(Detail info you can check patch link 
in below):

"2) tests, which set .mount_device = 1 and have more restrictive umask will not
work. Workaround would be to not use it and mount manually in the setup().
Or, reset umask with umask(0)."

BTW: for similar issues we also do fix within test file in stead of lib such as:
