# Validate Group Replication can be stopped even when replication channels are
# committing transactions concurrently.
#
# Test:
# 0. This test requires 2 servers:
# server1: group member
# server2: single server
# 1. Deploy a group on server1.
# 2. Configure a channel on server1 that replicates from
# server2.
# 3. Stop group on server1, through debug sync block the stop
# after acquiring `shared_plugin_stop` lock.
# 4. Commit a transaction on server2 which will be replicated
# to server1 through channel 'ch1'.
# Channel 'ch1' will fail since the plugin is stopping.
# 5. Resume STOP GROUP_REPLICATION on server1.
# 6. Clean up.
