# DESCRIPTION
# Verify zfs destroy test for range of snapshots by giving a list
# of valid and invalid arguments.
# STRATEGY
# 1. Create a list of valid and invalid arguments for range snapshot
# destroy.
# 2. Set up a filesystem and a volume with multiple snapshots
# 3. Run zfs destroy for all the arguments and verify existence of snapshots
# 4. Verify the destroy for snapshots with clones and hold
