Specification of test zones for NAMESERVER15

Table of contents

Background

See the test zone README file.

Test Case

This document specifies defined test zones for test case NAMESERVER15.

Test scenarios

The purpose of the test scenarios is to cover all reasonable contexts where different message tags are outputted when NAMESERVER15 is run on a test zone. The message tags are defined in the test case (NAMESERVER15) 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 delegated from the base name (nameserver15.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.

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.

Zone setup for test scenarios

Assumptions for the scenario specifications:

  • For each scenario zone there is one name server configured.
  • Unless stated otherwise, all name servers respond as follows:
    • Responds with a SOA record for the zone on query for SOA.
    • Responds with CH class on queries on CH class.
    • Software version query names are "version.bind" and "version.server".
    • All responses are 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.

NO-VERSION-REVEALED-1

This is a happy path

  • Zone: "no-version-revealed-1.nameserver15.xa."
    • The name server responds with empty answer section on both software version query names.

NO-VERSION-REVEALED-2

This is a happy path

  • Zone: "no-version-revealed-2.nameserver15.xa."
    • The name server responds with empty answer section on both software version query names.
    • The name server responds with RCODE Name "NxDomain" on both software version query names.

NO-VERSION-REVEALED-3

This is a happy path

  • Zone: "no-version-revealed-3.nameserver15.xa."
    • The name server responds with empty answer section on both software version query names.
    • The name server responds with RCODE Name "Refused" on both software version query names.

NO-VERSION-REVEALED-4

This is a happy path

  • Zone: "no-version-revealed-4.nameserver15.xa."
    • The name server responds with a single CNAME record and no other record in answer section on both software version query names.
      • "version.bind. CNAME version.server." when query name is version.bind.
      • "version.server. CNAME version.bind." when query name is version.server.

NO-VERSION-REVEALED-5

This is a happy path

  • Zone: "no-version-revealed-5.nameserver15.xa."
    • RDATA of the TXT records for both software version query names is the empty string.

NO-VERSION-REVEALED-6

This is a happy path

  • Zone: "no-version-revealed-6.nameserver15.xa."
    • RDATA of the TXT records for both software version query names only consists of space characters.

ERROR-ON-VERSION-QUERY-1

Unexpected response from server

  • Zone: "error-on-version-query-1.nameserver15.xa."
    • The name server responds with empty answer section on both software version query names.
    • The name server responds with RCODE Name "ServFail" on both software version query names.

ERROR-ON-VERSION-QUERY-2

Unexpected response from server

  • Zone: "error-on-version-query-2.nameserver15.xa."
    • The name server does not respond at all to the queries with the software version query names.

SOFTWARE-VERSION-1

Normal version string

  • Zone: "software-version-1.nameserver15.xa."
    • Empty response on software query name "version.bind".
    • TXT record with RDATA "v0" in response on software query name "version.server" in answer section.

SOFTWARE-VERSION-2

Normal version string

  • Zone: "software-version-2.nameserver15.xa."
    • Empty response on software query name "version.server".
    • TXT record with RDATA "v0" in response on software query name "version.bind" in answer section.

WRONG-CLASS-1

Version string returned in wrong class

  • Zone: "wrong-class-1.nameserver15.xa."
    • Empty response on software query name "version.bind".
    • TXT record with RDATA "v0" in response on software query name "version.server" in answer section.
      • TXT record is in IN class, not CH class.
