NAME
Test2::Suite - Distribution with a rich set of tools built upon the
Test2 framework.
DESCRIPTION
Rich set of tools, plugins, bundles, etc built upon the Test2 testing
library. If you are interested in writing tests, this is the
distribution for you.
WHAT ARE TOOLS, PLUGINS, AND BUNDLES?
TOOLS
Tools are packages that export functions for use in test files.
These functions typically generate events. Tools SHOULD NEVER alter
behavior of other tools, or the system in general.
PLUGINS
Plugins are packages that produce effects, or alter behavior of
tools. An example would be a plugin that causes the test to bail
out after the first failure. Plugins SHOULD NOT export anything.
BUNDLES
Bundles are collections of tools and plugins. A bundle should load
and re-export functions from Tool packages. A bundle may also load
and configure any number of plugins.
If you want to write something that both exports new functions, and
affects behavior, you should write both a Tools distribution, and a
Plugin distribution, then a Bundle that loads them both. This is
important as it helps avoid the problem where a package exports
much-desired tools, but also produces undesirable side-effects.
INCLUDED BUNDLES
Test2::V#
These do not live in the bundle namespace as they are the primary
ways to use Test2::Suite.
The current latest is Test2::V0.
use Test2::V0;
# strict and warnings are on for you now.
ok(...);
# Note: is does deep checking, unlike the 'is' from Test::More.
is(...);
...
done_testing;
This bundle includes every tool listed in the "INCLUDED TOOLS"
section below, except for Test2::Tools::ClassicCompare. This bundle
provides most of what anyone writing tests could need. This is also
the preferred bundle/toolset of the Test2 author.
See Test2::V0 for complete documentation.
Extended
** Deprecated ** See Test2::V0
use Test2::Bundle::Extended;
# strict and warnings are on for you now.
ok(...);
# Note: is does deep checking, unlike the 'is' from Test::More.
is(...);
...
done_testing;
This bundle includes every tool listed in the "INCLUDED TOOLS"
section below, except for Test2::Tools::ClassicCompare. This bundle
provides most of what anyone writing tests could need. This is also
the preferred bundle/toolset of the Test2 author.
See Test2::Bundle::Extended for complete documentation.
More
use Test2::Bundle::More;
use strict;
use warnings;
plan 3; # Or you can use done_testing at the end
ok(...);
is(...); # Note: String compare
is_deeply(...);
...
done_testing; # Use instead of plan
This bundle is meant to be a mostly drop-in replacement for
Test::More. There are some notable differences to be aware of
however. Some exports are missing: "eq_array", "eq_hash", "eq_set",
$TODO, "explain", "use_ok", "require_ok". As well it is no longer
possible to set the plan at import: "use .. tests => 5". $TODO has
been replaced by the todo() function. Planning is done using
"plan", "skip_all", or "done_testing".
See Test2::Bundle::More for complete documentation.
Simple
use Test2::Bundle::Simple;
use strict;
use warnings;
plan 1;
ok(...);
This bundle is meant to be a mostly drop-in replacement for
Test::Simple. See Test2::Bundle::Simple for complete
documentation.
INCLUDED TOOLS
Basic
Basic provides most of the essential tools previously found in
Test::More. However it does not export any tools used for
comparison. The basic "pass", "fail", "ok" functions are present,
as are functions for planning.
See Test2::Tools::Basic for complete documentation.
Compare
This provides "is", "like", "isnt", "unlike", and several
additional helpers. Note: These are all deep comparison tools and
work like a combination of Test::More's "is" and "is_deeply".
See Test2::Tools::Compare for complete documentation.
ClassicCompare
This provides Test::More flavored "is", "like", "isnt", "unlike",
and "is_deeply". It also provides "cmp_ok".
See Test2::Tools::ClassicCompare for complete documentation.
Class
This provides functions for testing objects and classes, things
like "isa_ok".
See Test2::Tools::Class for complete documentation.
Defer
This provides functions for writing test functions in one place,
but running them later. This is useful for testing things that run
in an altered state.
See Test2::Tools::Defer for complete documentation.
Encoding
This exports a single function that can be used to change the
encoding of all your test output.
See Test2::Tools::Encoding for complete documentation.
Exports
This provides tools for verifying exports. You can verify that
functions have been imported, or that they have not been imported.
See Test2::Tools::Exports for complete documentation.
Mock
This provides tools for mocking objects and classes. This is based
largely on Mock::Quick, but several interface improvements have
been added that cannot be added to Mock::Quick itself without
breaking backwards compatibility.
See Test2::Tools::Mock for complete documentation.
Ref This exports tools for validating and comparing references.
See Test2::Tools::Ref for complete documentation.
Spec
This is an RSPEC implementation with concurrency support.
See Test2::Tools::Spec for more details.
Subtest
This exports tools for running subtests.
See Test2::Tools::Subtest for complete documentation.
Target
This lets you load the package(s) you intend to test, and alias
them into constants/package variables.
See Test2::Tools::Target for complete documentation.
INCLUDED PLUGINS
BailOnFail
The much requested "bail-out on first failure" plugin. When this
plugin is loaded, any failure will cause the test to bail out
immediately.
See Test2::Plugin::BailOnFail for complete documentation.
DieOnFail
The much requested "die on first failure" plugin. When this plugin
is loaded, any failure will cause the test to die immediately.
See Test2::Plugin::DieOnFail for complete documentation.
ExitSummary
This plugin gives you statistics and diagnostics at the end of your
test in the event of a failure.
See Test2::Plugin::ExitSummary for complete documentation.
SRand
Use this to set the random seed to a specific seed, or to the
current date.
See Test2::Plugin::SRand for complete documentation.
UTF8
Turn on utf8 for your testing. This sets the current file to be
utf8, it also sets STDERR, STDOUT, and your formatter to all output
utf8.
See Test2::Plugin::UTF8 for complete documentation.
INCLUDED REQUIREMENT CHECKERS
AuthorTesting
Using this package will cause the test file to be skipped unless
the AUTHOR_TESTING environment variable is set.
See Test2::Require::AuthorTesting for complete documentation.
EnvVar
Using this package will cause the test file to be skipped unless a
custom environment variable is set.
See Test2::Require::EnvVar for complete documentation.
Fork
Using this package will cause the test file to be skipped unless
the system is capable of forking (including emulated forking).
See Test2::Require::Fork for complete documentation.
RealFork
Using this package will cause the test file to be skipped unless
the system is capable of true forking.
See Test2::Require::RealFork for complete documentation.
Module
Using this package will cause the test file to be skipped unless
the specified module is installed (and optionally at a minimum
version).
See Test2::Require::Module for complete documentation.
Perl
Using this package will cause the test file to be skipped unless
the specified minimum perl version is met.
See Test2::Require::Perl for complete documentation.
Threads
Using this package will cause the test file to be skipped unless
the system has threading enabled.
Note: This will not turn threading on for you.
See Test2::Require::Threads for complete documentation.
SEE ALSO
See the Test2 documentation for a namespace map. Everything in this
distribution uses Test2.
Test2::Manual(3) is the Test2 Manual.
