# ID: zfs_receive_005_neg
#
# DESCRIPTION:
#	Verify 'zfs receive' fails with unsupported scenarios.
#	including:
#	(1) Invalid send streams;
#	(2) The received incremental send doesn't match the filesystem
#	    latest status.
#
# STRATEGY:
#	1. Preparation for unsupported scenarios 
#	2. Execute 'zfs receive' 
#	3. Verify the results are failed
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-09-06)
#
