# ID: zfs_snapshot_001_neg
#
# DESCRIPTION: 
#	Try each 'zfs snapshot' with inapplicable scenarios to make sure
#	it returns an error. include:
#		* No arguments given.
#		* The argument contains invalid characters for the ZFS namesapec
#		* Leading slash in snapshot name
#		* The argument contains an empty component.
#		* Missing '@' delimiter.
#		* Multiple '@' delimiters in snapshot name.
#		* The snapshot already exist.
#		* Create snapshot upon the pool. 
#			(Be removed since pool is treated as filesystem as well)
#		* Create snapshot upon a non-existent filesystem.
#		* Too many arguments. 
#
# STRATEGY:
#	1. Create an array of parameters
#	2. For each parameter in the array, execute the sub-command
#	3. Verify an error is returned.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-26)
