Template sample

router set templamte is put on './set_templates' directory.

interfaces {
   {{ interface_name }} {
        unit 0 {            
            description {{ interface_description }};
            family inet {
                address {{ interface_address_ipv4 }}/{{ interface_subnet_ipv4 }};
            }
        }
    }
}

router test template is put on './nwtest_templates' directory.

test_interface_{{ interface_name }}_{{ interface_status }}:
  - command: show interfaces terse {{ interface_name }}
  - item:
      xpath: physical-interface
      tests:
        - is-equal: admin-status, {{ interface_status }}
        - is-equal: oper-status, {{ interface_status }}
