Where does this Testlib directory resides? And what type is the partition?
If it resides into the windows partition, then permissions are not relevant since these partitions will not support linux permissions. If it resides in the linux partition and you booted on single user, then the root partition will be mounted read only as I said above.
In this caes, you will need to boot from a livecd, mount your root partition anywhere and then change the permissions or do whatever from there.
