#
# ==== Purpose ====
#
# This test checks that  the slave generates and applies binary diffs of partial
# json events when the binlog option binlog_row_value_options=PARTIAL_JSON on
# the master side only.
# It also checks that the binary diffs will only contain the relevant fields
# when binlog_row_image is set to minimal and even whent he slave has extra
# columns in the modified table.
