# This test validates that while a member is recovering through clone,
# certification info garbage collection continues to happen.
#
# 0. The test requires three servers: M1, M2 and M3.
# 1. Install the clone plugin and bootstrap group
# replication on server1.
# 2. Start group replication on server3.
# 3. Restart server 2 with a monitoring process (mysqld_safe) if needed
# 4. Install the clone plugin on server 2
# Setup the server so group replication starts on boot
# 5. Start group replication on server 2
# Set a debug point so it blocks during clone.
# 6. Assert COUNT_TRANSACTIONS_ROWS_VALIDATING and
# TRANSACTIONS_COMMITTED_ALL_MEMBERS values on all servers.
# 7. Assert COUNT_TRANSACTIONS_ROWS_VALIDATING and
# TRANSACTIONS_COMMITTED_ALL_MEMBERS values on all servers
# after a garbage collection round.
# 8. Resume clone.
# Check process finished and server2 is online
# 9. Assert COUNT_TRANSACTIONS_ROWS_VALIDATING and
# TRANSACTIONS_COMMITTED_ALL_MEMBERS values on all servers
# once all members are ONLNE.
# 10. Cleanup
