# Perform some simple tests about getting/setting communication_protocol.
#
# This test uses 2 servers.
#
# Test:
# 1. Start 2 servers and add them into group replication group.
# 2. Decrease communication_protocol.
# 3. Increase communication_protocol.
# 4. Confirm invalid calls to group_replication_get_communication_protocol.
# 5. Confirm invalid calls to group_replication_set_communication_protocol.
# 6. Stop GR and try to call UDFs outside of a group.
