gnmi_subscriptionlist_test

GNMI-2: gnmi_subscriptionlist_test

Summary

This is to test for gNMI Subscription to multiple paths with different SubscriptionMode in a single SubscriptionRequest message using the Subscriptionlist field. Goal here is to,

• Ensure that the NOS supports "Subscriptionlist" field with multiple Subscription messages and also supports the desired Subscriptionmode per path in each Subscription message.
• The tests also check if the DUT is responding back everytime with a SubscriptionResponse message that has the sync_response field set to true

Procedure

GNMI-2.1: Verify single subscription request with a Subscriptionlist and different SubscriptionModes:

• Send a single SubscribeRequest message to the DUT with a SubcriptionList and SubscriptionMode matching the "Telemetry Parameter Coverage" section below. Use Stream mode for the SubcribeRequest.
• Ensure that the implementation successfully allows subscription to all the paths mentioned below and a SubscribeResponse message is received by the client with the sync_reponse field set to true. The RPC via which the SubscribeRequest was recieved should eventually be closed by the client.

GNMI-2.2: Change SubscriptionModes in the subscription list and verify receipt of sync_response:

• In the "Telemetry Parameter coverage" section below, change the Subscribe message for each of the paths with SubscriptionMode as ON_CHANGE to TARGET_DEFINED and the ones that are TARGET_DEFINED to SAMPLE w/ a sampe_interval of 10secs and send all the subscribe messages in a single SubscribeRequest message to the DUT. Confirm that a SubscribeResponse message is received by the client with the sync_reponse field set to true. The client should then close the RPC session
• Again, switch the SubscriptionMode in each Subscription message to its original state i.e. from TARGET_DEFINED to ON_CHANGE and from SAMPLE to TARGET_DEFINED and resend the SubscriptionRequest with Mode as STREAM. Confirm that the DUT is responding back to the client with a SubscriptionResponse and the Sync_Response field set to true
