If the default user inside docker is non root user, test will report fails "mkdir: cannot create directory '/sys/fs/cgroup/memory': Permission denied". I think it's better to throw SkippedException rather than report failure when it's do not have root permission inside docker.

I think this has been discussed in the past and it was considered a test environment configuration error and so should be reported rather than being silently ignored.
