# Validate that column last_conflict_free_transaction from
# performance_schema.replication_group_member_stats table
# always show the last conflict free transaction.
#
# Steps:
#   0. The test requires two servers: M1 and M2.
#   1. With both members ONLINE. Assert that last_conflict_free_transaction is
#      correct when last transaction GTID was generated on M1 and M2.
#   2. Assert that last_conflict_free_transaction is correct
#      when last transaction GTID was specified on M1 and M2.
#   3. Clean up.
