# test cases for "--disable_abort_on_error"
#
# "--disable_abort_on_error" switches the abort of mysqltest
# after "unmasked" failing statements off.

# The default is "--enable_abort_on_error".
#
# "Maskings" are
#   --error <error number>  and  --error <error number>
# in the line before the failing statement.
#
# There are some additional test case for $mysql_errno
# because "--disable_abort_on_error" enables a new situation.
# Example: "unmasked" statement fails + analysis of $mysql_errno
