Background

See the test scenario README file.

Test Case

This document specifies defined test scenarios for test case Basic02.

Test scenarios

The purpose of the test scenarios is to cover all reasonable contexts where different message tags are outputted when Basic02 is run on a test zone. The message tags are defined in the test case (Basic02) 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 or zones for each test scenario in this document is a subdomain (or lower zone) delegated from the base name (basic02.xa) and that subdomain having the same name as the scenario. The names of those zones are given in section "Test scenarios and setup of test zones" below.

All message tags

The test case can output any of these message tags, but not necessarily in any combination. See Basic02 for the specification of the tags.

• B02_AUTH_RESPONSE_SOA
• B02_NO_DELEGATION
• B02_NO_WORKING_NS
• B02_NS_BROKEN
• B02_NS_NOT_AUTH
• B02_NS_NO_IP_ADDR
• B02_NS_NO_RESPONSE
• B02_UNEXPECTED_RCODE

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 scenarios and setup of test zones

Default zone configuration

Unless otherwise specified in the specific scenario specification, the test zone or zones for the scenario will follow the default setup as stated below. The child zone is the zone to be tested for the scenario.

basic02.xb is a zone for out-of-bailiwick name servers for applicable scenario.

• The child zone is SCENARIO.basic02.xa.
  • It is delegated to two name servers, ns1.SCENARIO.basic02.xa and ns2.SCENARIO.basic02.xa.
    • The name server names have A and AAAA records to avoid non-relevant error messages.
    • The delegation of the child zone is complete with glue records.
  • There is a zone file for the child zone.
  • All child zone servers give the same response.
• All responses will have the AA bit set.
• All responses will have the RCODE Name "NoError".
• NS and any glue matches NS and authoritative address records in zone.
• If NS are out of bailiwick, the names are defined in another zone with correct A and AAAA records.

GOOD-1

A "happy path". Everything is fine.

• Zone: good-1.basic02.xa
  • Zone is set up as default.

GOOD-2

Like GOOD-1 but name servers are out-of-bailiwick.

• Zone: good-1.basic02.xa
  • ns1 is ns1.good-2.basic02.xb.
  • ns2 is ns2.good-2.basic02.xb.
  • Delegation is without glue.
