# DESCRIPTION:
#	'zfs promote' will fail with invalid arguments:
#	(1) NULL arguments
#	(2) non-existent clone
#	(3) non-clone datasets:
#		pool, fs, snapshot,volume
#	(4) too many arguments.
#	(5) invalid options
#
# STRATEGY:
#	1. Create an array of invalid arguments
#	2. For each invalid argument in the array, 'zfs promote' should fail
#	3. Verify the return code from zfs promote
#
