# WL#7660 - GCS PLUGIN IMPLEMENTATION
#
# This test checks the basic functionality of the Group Replication replication
# plugin: the installation, uninstallation of the plugin and the
# update of the plugin status variables.
#
# Test:
# 0. The test requires one server.
# 1. Set group_replication_group_name=<INVALID_VALUE>. Expect error.
# 2. Set group_replication_group_name=<VALID_VALUE>. Assert check the value.
# - Set group_replication_start_on_boot=1. Assert check the value.
# 3. Restart server to check that plugin is still loaded.
# 4. After the server restart the group name is again set to NULL. Thus, START
# GROUP_REPLICATION (GR) command must fail.
# 5. Start GR command will succeed when group name is set to valid value.
# 6. Try start GR command again. It must error out since the group is already
# running. Start GR with valid value. It must start.
# 7. Set group_replication_group_name=<VALID_VALUE>. It must error out i.e. we
# cannot set group name when group is running.
# 8. Clean up.
