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.

Test::FailWarnings adds test failures if warnings are caught.

This package provides a rich set of tools, plugins, bundles, etc built upon the Test2 testing library.

Test::Manifest overrides the default test file order. Instead of running all of the t/*.t files in ASCII-betical order, it looks in the t/test_manifest file to find out which tests you want to run and the order in which you want to run them. It constructs the right value for the build system to do the right thing.

This module was written to ensure that a META.yml file meets the specification.

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

This module is primarily (but not exclusively) for use in test scripts: A block eval configurable and extensible but by default trapping STDOUT, STDERR, warnings, exceptions, would-be exit codes, and return values from boxed blocks of test code.

This module can test routines that manipulate random numbers by providing a known output from rand. Given a list of seeds with srand, it will return each in turn. After seeded random numbers are exhausted, it will always return 0. Seed numbers must be of a form that meets the expected output from rand as called with no arguments: they must be between 0 (inclusive) and 1 (exclusive). In order to facilitate generating and testing a nearly-one number, this module exports the function oneish, which returns a number just fractionally less than one.

In situations where you have deep trees of classes, there is a common situation in which you test a module 4 or 5 subclasses down, which should follow the correct behaviour of not just the subclass, but of all the parent classes.

This should be done to ensure that the implementation of a subclass has not somehow ``broken'' the object's behaviour in a more general sense.

Test::Object is a testing package designed to allow you to easily test what you believe is a valid object against the expected behaviour of all of the classes in its inheritance tree in one single call.

Test::Tester allows testing of test modules based on Test::Builder with a minimum of effort.

The Test::WriteVariants module provides for the dynamic generation of tests in nested combinations of contexts.

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.

This module causes any warnings during testing to be captured and stored. It automatically adds an extra test that will run when your script ends to check that there were no warnings. If there were any warnings, the test will fail and output diagnostics of where, when and what the warning was, including a stack trace of what was going on when it occurred.

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.

Test::Portability::Files module is used to check the portability across operating systems of the names of the files present in the distribution of a module. The tests use the advices given in 'Files and Filesystems' in perlport. The author of a distribution can select which tests to execute.

Test::Simple contains basic utilities for writing tests.

This Perl module is intended to easily test network connectivity to non-local Internet resources before functional tests begin. If the sockets cannot connect to the specified hosts and ports, the exception is caught and reported, and the tests skipped.

This module contains a collection of acceptance tests for implementations of Future::IO.

Using Test::PerlTidy, any file ending in .pl, .pm, .t or .PL will cause a test fail unless it is exactly as perltidy would like it to be.

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

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

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

This module is a collection of tests useful for dealing with UTF-8 strings in Perl. This module has two types of tests: The validity tests check if a string is valid and not corrupt, whereas the characteristics tests will check that string has a given set of characteristics.
