Test::Run is an improved test harness, originally based on Test::Harness version 2.xx by Michael G. Schwern, Andy Lester and others.

The top-level "Test::Run" by itself does not do much. You should refer to Task::Test::Run::AllPlugins for more detailed instructions.

This module provides basic Boolean support, by defining two special objects: true and false.

Crypt::RandPasswd provides three functions that can be used to generate random passwords, constructed from words, letters, or characters. This code is a Perl implementation of the Automated Password Generator standard, like the program described in "A Random Word Generator For Pronounceable Passwords". This code is a re-engineering of the program contained in Appendix A of FIPS Publication 181, "Standard for Automated Password Generator".

List::SomeUtils provides some trivial but commonly needed functionality on lists which is not going to go into List::Util.

All of the below functions are implementable in only a couple of lines of Perl code. Using the functions from this module however should give slightly better performance as everything is implemented in C. The pure-Perl implementation of these functions only serves as a fallback in case the C portions of this module couldn't be compiled on this machine.

The functions exported by this module deal with runtime handling of Perl modules, which are normally handled at compile time.

When searching through large amounts of data, it is often the case that a result set is returned that is larger than we want to display on one page. This results in wanting to page through various pages of data. The maths behind this is unfortunately fiddly, hence this module.

perlcritic is a Perl source code analyzer. It is the executable front-end to the Perl::Critic engine, which attempts to identify awkward, hard to read, error-prone, or unconventional constructs in your code. Most of the rules are based on Damian Conway's book "Perl Best Practices". However, perlcritic is not limited to enforcing PBP, and it will even support rules that contradict Conway. All rules can easily be configured or disabled to your liking.

This module provides a Perl interface to the iconv() codeset conversion function, as defined by the Single UNIX Specification. For more details see the POD documentation embedded in the file Iconv.pm, which will also be installed as Text::Iconv(3) man page.

Carp::Assert is intended for a purpose like the ANSI C library assert.h.

Authen::DecHpwd implements the SYS$HASH_PASSWORD password hashing function from VMS (also known as LGI$HPWD) and some associated VMS username and password handling functions. The password hashing function is implemented in XS with a pure Perl backup version for systems that cannot handle XS.

This module can retrieve information from the CDDB.

You use Tie::Cycle to go through a list over and over again. Once you get to the end of the list, you go back to the beginning.

This module splits a set of data with IDs and arbitrary values into one test file per (key+value) for easy parallelisation.

Log::Any::Adapter::Log4perl provides a Log::Any adapter using Log::Log4perl for logging.

Data::OptList provides a simple syntax for name/value option pairs.

This module provides tools to deal with International Standard Serial Numbers.

This module provides syntactical support for try/catch control flows.

Module::ScanDeps is a module to recursively scan Perl programs for dependencies.

When an undefined variable is dereferenced, it gets silently upgraded to an array or hash reference (depending of the type of the dereferencing). This behaviour is called autovivification and usually does what you mean but it may be unnatural or surprising because your variables get populated behind your back. This is especially true when several levels of dereferencing are involved, in which case all levels are vivified up to the last, or when it happens in intuitively read-only constructs like exists. The pragma provided by this package lets you disable autovivification for some constructs and optionally throws a warning or an error when it would have happened.

This module provides lexicon-handling modules to read from other localization formats, such as Gettext, Msgcat, and so on.

This is a minimalist Perl module for building simple classes with read-only accessors.

This module provides routines for parsing date string into time values and formatting dates into ASCII strings.

This module is allows applications to retrieve per-user characteristics.

Term::ProgressBar::Simple tells you how much work has been done, how much is left to do, and estimate how long it will take.
