# 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.
