Test::More::UTF8 is a simple extension for the widely used Test::More module. By default, it will do a binmode :utf8 on all of Test::Builder's output handles thus enabling the easy use flagged strings without warnings like "Wide character in print …"

Test::Memory::Cycle is built on top of Devel::Cycle to give you an easy way to check for these circular references.

use Test::Memory::Cycle;

my $object = new MyObject;
# Do stuff with the object.
memory_cycle_ok( $object );

This module creates a Fake ShareDir for your modules for testing.

Test::TrailingSpace tests for trailing spaces in Perl source files.

Test::NoTabs lets you check the presence of tabs in your perl code.

This module adds a test to your Perl distribution which checks for pod coverage of all appropriate files.

This module allows you to deliberately hide modules from a program even though they are installed. This is mostly useful for testing modules that have a fallback when a certain dependency module is not installed.

This module provides some drop-in replacements for the string comparison functions of Test::More, but which are more suitable when you test against long strings.

This module provides routines for testing the exit status, standard output and standard error of external commands.

Test::YAML is a subclass of Test::Base with YAML specific support.

Test::File::Contents provides functions for testing the contents of files.

Test::Version checks to ensure that all modules have a version defined, and that the version is valid.

Test::File provides a collection of test utilities for file attributes.

Test::Filename provides functions to convert all path separators automatically.

The Mock::Config Perl module allows temporarily setting and overriding Config values, even for the readonly XSConfig implementation as used in cperl. It does not store the mocked overrides lexically, just dynamically.

Fennec ties together several testing related modules and enhances their functionality in ways you don't get loading them individually. Fennec::Lite takes a minimalist approach to do for Fennec what Mouse does for Moose.

Test::EOL lets you check for the presence of trailing whitespace and/or windows line endings in your perl code.

This module provides a few convenience methods for testing warning based code.

This module is intended to be used as a drop-in replacement for Test::NoWarnings. It also adds an extra test, but runs this test before done_testing calculates the test count, rather than after. It does this by hooking into done_testing as well as via an END block. You can declare a plan, or not, and things will still Just Work.

Test::File::ShareDir is some low level plumbing to enable a distribution to perform tests while consuming its own share directories in a manner similar to how they will be once installed.

Test::Output provides a simple interface for testing output sent to STDOUT or STDERR. A number of different utilities are included to try and be as flexible as possible to the tester.

Tainted data is data that comes from an unsafe source, such as the command line, or, in the case of web apps, any GET or POST transactions. Read the perlsec man page for details on why tainted data is bad, and how to untaint the data.

When you're writing unit tests for code that deals with tainted data, you'll want to have a way to provide tainted data for your routines to handle, and easy ways to check and report on the taintedness of your data, in standard Test::More style.

This module provides a collection of test utilities for directory attributes.

This module exports three test functions and four diff-style functions.
