This test validates the behavior of gNMI Replace and Update operations on a leaf-list field in the OpenConfig model. The test specifically targets the /system/dns/config/search path.

The test follows these steps:

1. Initial Replace: It uses a gNMI Replace operation to set the value of /system/dns/config/search to ["google.com"].
2. Validation: It verifies that the DUT successfully updated the path and that the new value is ["google.com"].
3. Update: It then uses a gNMI Update operation to add "youtube.com" to the existing leaf-list.
4. Final Validation: It verifies that the leaf-list at /system/dns/state/search now contains both "google.com" and "youtube.com".

The test will fail if the values at any stage do not match the expected results.

{
  "system": {
    "dns": {
      "config": {
        "search": [
          "google.com",
          "youtube.com"
        ]
      }
    }
  }
}
