Background

See the test scenario README file.

Test Case

This document specifies test scenarios for test case Delegation03.

Test scenarios

The purpose of the test scenarios is to cover all reasonable contexts where different message tags are output when Delegation03 is run on a test zone. The message tags are defined in the test case (Delegation03) and the scenarios are defined below.

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

Test zone names

The test zone for each test scenario in this document is a subdomain delegated from the base name (delegation03.xa) and that subdomain having the same name as the scenario. The names of those zones are given in section Test zone setup below.

All message tags

The test case can output any of these message tags, but not necessarily in any combination. See Delegation03 for the specification of the tags.

• REFERRAL_SIZE_OK
• REFERRAL_SIZE_TOO_LARGE

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"

Test zone setup

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

• For each scenario zone there are two name server configured.
  • Both name servers are in-bailiwick.
  • Both name servers have both IPv4 and IPv6 addresses.
  • All addresses are distinct.
  • All required glue are present in the delegation.
  • There is no actual zone or zone file, only a delegation.
    • For these scenarios only the delegation is needed.

REFERRAL-SIZE-OK-1

This is the happy path.

• Zone: referral-size-ok-1.delegation03.xa.

REFERRAL-SIZE-OK-2

Referral is large, but not too large. The name servers are in-bailiwick.

• Zone: referral-size-ok-2.delegation03.xa.
  • ns1 is "ns1.ipv4-large-but-not-too-large.referral-size-ok-2.delegation03.xa".
  • ns1 is "ns1.ipv6-large-but-not-too-large.referral-size-ok-2.delegation03.xa".
  • ns2 is "ns2.ipv4-large-but-not-too-large.referral-size-ok-2.delegation03.xa".
  • ns2 is "ns2.ipv6-large-but-not-too-large.referral-size-ok-2.delegation03.xa".

REFERRAL-SIZE-TOO-LARGE-1

Referral is too large and name servers are in-bailiwick.

• Zone: referral-size-too-large-1.delegation03.xa
  • Name server names are relative to the zone name:
    • ns1 is "ns1.1abcdefghijklmnopqrstuv.1defghijkl"
    • ns2 is "ns2.2abcdefghijklmnopqrstuv.2defghijkl"
    • ns3 is "ns3.2abcdefghijklmnopqrstuv.3defghijkl"
    • ns4 is "ns4.2abcdefghijklmnopqrstuv.4defghijkl"
    • ns5 is "ns5.2abcdefghijklmnopqrstuv.5defghijkl"

REFERRAL-SIZE-TOO-LARGE-2

Referral is too large and name servers are out-of-bailiwick with no glue.

• Zone: referral-size-too-large-2.delegation03.xa
  • The zone is delegated to ns1, ns2, ns3 and ns4.
    • ns1 is "ns1.1abcdefghijklmnopqrstuvwxyz.1abcdefghijklmnopqrstuvwxy.1abcdefghijklmnopqrstuvw.referral-size-too-large-2.delegation03.xb"
    • ns2 is "ns2.2abcdefghijklmnopqrstuvwxyz.2abcdefghijklmnopqrstuvwxy.2abcdefghijklmnopqrstuvw.referral-size-too-large-2.delegation03.xb"
    • ns3 is "ns3.3abcdefghijklmnopqrstuvwxyz.3abcdefghijklmnopqrstuvwxy.3abcdefghijklmnopqrstuvw.referral-size-too-large-2.delegation03.xb"
    • ns4 is "ns4.4abcdefghijklmnopqrstuvwxyz.4abcdefghijklmnopqrstuvwxy.4abcdefghijklmnopqrstuvw.referral-size-too-large-2.delegation03.xb"
  • Delegation is without glue.
  • The test zone has no address records for the name server names.
  • The "delegation03.xb" zone has full set of address records (IPv4 and IPv6).
