# 0. Start GR on with 2 servers
# 1. Perform some DDL/DML operations on a member
# 2. Create a backup from the member using mysqldump
# 3. Verify if that backup can be later restored successfully on a 3rd server
# 4. See if that 3rd server can then be added to GR group
# 5. Perform some DDL/DML operations on the group
# 6. Cleanup
