Background

See the test zone README file.

Test Case

This document specifies defined test zones for test case Basic01.

Test scenarios

The purpose of the test scenarios is to cover all reasonable contexts where different message tags are outputted when Basic01 is run on a test zone. The message tags are defined in the test case (Basic01) and the scenarios are defined below.

The test scenarios are structured as stated in the test zone README file.

Test zone names

The test zone for each test scenario in this document is a subdomain (or lower zone) delegated from the base name (basic01.xa) and that subdomain having the same name as the scenario. The names of those zones are given in section "Zone setup for test scenarios" below.

All tags

The test case can output any of these message tags, but not necessarily in any combination.

• B01_CHILD_FOUND
• B01_CHILD_IS_ALIAS
• B01_INCONSISTENT_ALIAS
• B01_INCONSISTENT_DELEGATION
• B01_NO_CHILD
• B01_PARENT_DISREGARDED
• B01_PARENT_FOUND
• B01_PARENT_NOT_FOUND
• B01_PARENT_UNDETERMINED
• B01_ROOT_HAS_NO_PARENT
• B01_SERVER_ZONE_ERROR

Test scenarios and message tags

If a message tag is not listed for the scenario, its presence or non-presence is irrelevant to the test scenario and must be ignored.

• (1) All tags except for those specified as "Forbidden message tags" (no instances for these test scenarios)
• (2) All tags except for those specified as "Mandatory message tags"

Zone setup for test scenarios

Assumptions for the scenario specifications unless otherwise specified for the specific scenario:

• The child zone is child.parent.SCENARIO.basic01.xa.
  • It is delegated to two name servers, ns1-delegated-child.basic01.xa and ns2-delegated-child.basic01.xa.
    • The name server names have A and AAAA records to avoid non-relevant error messages.
    • There is no zone file or zone data for the child zone.
  • If there is an undelegated "version" of the child zone, it is referred to ns3-undelegated-child.basic01.xa and ns4-undelegated-child.basic01.xa.
    • The name server names have A and AAAA records to avoid non-relevant error messages.
    • There is no zone file or zone data for the undelegated "version".
• The parent zone is parent.SCENARIO.basic01.xa.
  • It is served by two in-bailiwick NS (ns1 and ns2).
  • ns1 and ns2 have the same zone content.
  • ns1 and ns2 have both IPv4 and IPv6 glue.
  • The records matching glue in the zone are complete.
  • The delegation from the grand parent has the same NS with complete glue.
• The grandparent zone is SCENARIO.basic01.xa.
  • It is served by two in-bailiwick NS (ns1 and ns2).
  • ns1 and ns2 have the same zone content.
  • ns1 and ns2 have both IPv4 and IPv6 glue.
  • The records matching glue in the zone are complete.
  • The delegation from the SCENARIO zone has the same NS with complete glue.
• Responds with a A record for the zone on query for A.
• Responds with a AAAA record for the zone on query for AAAA.
• All responses are authoritative with RCODE Name "NoError"
• EDNS, version 0, is included in all responses on queries with EDNS.
• EDNS is not included in responses on queries without EDNS.
• Standard test zone root is used.
• In all cases, delegation and zone are consistent.
  • Same NS.
  • Any required glue matches address records in zone.
  • No extra address records for the NS names.
