# STOP GROUP_REPLICATION will signal group coordination process and loop until
# all UDF terminate.
#
# Test:
# 0. This test requires two servers on multi primary mode
# 1. Activate debug point will block action after verify plugin isn't
# stopping
# 2. Start action switch to single primary mode
# 3. Wait for action hit the debug point
# 4. STOP Group Replication on server1
# 5. Wait for member state is OFFLINE
# 6. To improve test but without adding more debug code, sleep to allow
# STOP Group Replication loop until UDF function finishes
# 7. Assert STOP GROUP_REPLICATION thread still runs
# 8. Signal the action to continue
# 9. Reap execution of action and confirm it failed
# 10. Reap with success the execution of STOP GROUP_REPLICATION
# 11. Cleanup
