Purpose
=======
The purpose of the Whois Selftest Tool is to help gTLD applicants prepare for
[Pre-Delegation Testing]( http://newgtlds.icann.org/en/applicants/pdt) (PDT) by
providing pre-PDT Whois output validation.

Scope
=====
While Whois Selftest Tool _does_ validate Whois output and it _does_ strive to
reflect the state of PDT Whois output validation, it _is not_ authoritative on
the outcome of PDT and it _is_ subject to change.

Disclaimer
----------
The Whois Selftest Tool and the actual Whois testing under PDT are not equal.
We strive to make the two as equal as possible, but here is no guarantee that 
successfully running the Whois Selftest Tool means
that the same Whois system will pass the Whois testing under PDT. For example,
the parts of Whois tests under Whois that include DNS lookups and TCP
connections are not included in the Whois Selftest Tool. For a complete
reference of the Whois tests under PDT see the PDT Whois documents.

Version history
===============
* v1.0.0 - Initial public release (2015-12-03)
* v1.1.0 - Updated public release (2016-01-08)
* v1.2.0 - Updated public release (2016-02-02)
* v1.3.0 - Updated public release (2016-02-26)

The v1.1.0 release primarily matches the updates to the PDT Whois TP and TCs in the version 2.9 document release. It also handles the issue with IDN in the v1.0.0 release and corrects found bugs.

The v1.2.0 release primarily matches the updates to the PDT Whois TP in the the version 2.10 document release. It also corrects found bugs.

The v1.3.0 release includes two updates of the PDT Whois TP that will be included in the next document release:

* If the Domain Status is "ok" then the fragment in the URL in the Domain Status field may be "ok" or "OK".
* If a field is empty (key is there, but no value) there may be one space character (U+0020) after the colon, i.e. trailing space is permitted.

  Specifications zip, specifies the test cases that the Whois Selftest Tool
  partially implements.

The Whois Selftest Tool has been developed on Unbuntu Linux, but we have tried to
avoid Linux specific coding. There is, however, no guarantee that it works on
other OSs.

Installation
============
Clone the project repository and choose version according to the specification
compatibility matrix. In the normal case, choose the latest version.

    $> git clone https://github.com/dotse/Whois-Selftest-Tool.git <srcdir>
    $> cd <srcdir>
    $> git checkout <version>

Install Whois Selftest Tool scripts and libraries.

    $> perl Build.PL
    $> ./Build
    $> ./Build test
    $> ./Build install

To check the installation run the scripts with `--help`. Before the whois-test
script can be run, the EPP database must be fetched.

    $> whois-fetch-epp-repo-ids --help
    $> whois-fetch-epp-repo-ids
    $> whois-test --help

After installing, you can find documentation for this module with the
perldoc command.

    perldoc PDT::TS::Whois

Before use
==========
Before you use the tool, make sure that you have read the documents listed
in the reference above. Some error messages may be difficult to understand
without referring to the PDT\_Whois\_TP document.

Usage
=====
The Whois Selftest Tool provides the two commands `whois-fetch-epp-repo-ids`
and `whois-test`. If you have followed the installation above, always go to
your `<programdir>` and run the commands from there or else the scripts will
not be able to find its libraries in the `PDT` directory. You probably have to
prepend the commands with `./` just as in the instructions above.

`whois-fetch-epp-repo-ids` fetches the EPP Repository Identifiers registered
with IANA and stores them in a text file inside the user's home directory.

`whois-test` validates the Whois responses according to the format specification
in the PDT\_Whois\_TP document.

The database of EPP Repository Identifiers is a prerequisite for running
`whois-test` command, so `whois-fetch-epp-repo-ids` must be run at least once
before `whois-test` is used for the first time.  After that, run
`whois-fetch-epp-repo-ids` again to update the database every time 
the Whois Selfttest Tool is to be used.

See the man pages for the respective commands for details on how to run them.
(You can use the `--man` option to view the man pages)

Known issues
============

* The description of the two types of replies on queries for nameserver objects is a bit unclear. For full understanding, please see the PDT Test Case WhoisCLI03 found in the PDT\_Whois\_TC\_CLI document listed in the references above.
