# WL#6841 - GCS Replication: P_S table to show GCS kernel stats
#
# This test checks the basic functionality of the Group Replication
# P_S for replication_connection_status table.
# DDL and DML testing for this table is addressed in other tests.
#
# The follwing scenarios are tested:
#  0. The test requires one server: M1.
#  1. Checking that GR channel in replication_connection_status is not present
#     before group_replication on M1.
#  2. Bootstrap start M1. Validate group_name to valid name and service_state=ON.
#  3. On stop GR, validate group_name to valid name and service_state=OFF.
#  4. Check that group_name is reset if mysql server restarts.
#  5. Verify that the group_name and source_uuid are not preserved when plugin
#     is uninstalled.
