Test2::V0(3)

NAME
Test2::V0 - 0Th edition of the Test2 recommended bundle.

DESCRIPTION
This is the big-daddy bundle. This bundle includes nearly every tool, and several plugins, that the Test2 author uses. This bundle is used extensively to test Test2::Suite itself.

NAMING, USING, DEPENDING
This bundle should not change in a severely incompatible way. Some minor breaking changes, specially bugfixes, may be allowed. If breaking changes are needed then a new "Test2::V#" module should be released instead.

As new "V#" modules are released old ones may be moved to different cpan distributions. You should always use a specific bundle version and list that version in your distributions testing requirements. You should never simply list Test2::Suite as your modules dep, instead list the specific bundle, or tools and plugins you use directly in your metadata.

SYNOPSIS
    use Test2::V0;

    ok(1, "pass");

    ...

    done_testing;

RESOLVING CONFLICTS WITH MOOSE
    use Test2::V0 '!meta';

Moose and Test2::V0 both export very different meta() subs. Adding '!meta' to the import args will prevent the sub from being imported. This bundle also exports the sub under the name meta_check() so you can use that spelling as an alternative.

  TAGS

:DEFAULT
    The following are both identical:

        use Test2::V0;

        use Test2::V0 ':DEFAULT';

  RENAMING ON IMPORT
    use Test2::V0 ':DEFAULT', '!ok', ok => {-as => 'my_ok'};

This bundle uses Test2::Util::Importer for exporting, as such you can use any arguments it accepts.

Explanation:

'!ok'
    Do not export ok()

ok => {-as => 'my_ok'}
    Actually, go ahead and import ok() but under the name my_ok().

If you did not add the '!ok' argument then you would have both ok() and my_ok()

PRAGMAS
All of these can be disabled via individual import arguments, or by the "-no_pragmas" argument.

    use Test2::V0 -no_pragmas => 1;

  STRICT
strict is turned on for you. You can disable this with the "-no_strict" or "-no_pragmas" import arguments:

    use Test2::V0 -no_strict => 1;

  WARNINGS
warnings are turned on for you. You can disable this with the "-no_warnings" or "-no_pragmas" import arguments:

    use Test2::V0 -no_warnings => 1;

  UTF8
This is actually done via the Test2::Plugin::UTF8 plugin, see the "PLUGINS" section for details.

Note: "-no_pragmas => 1" will turn off the entire plugin.

PLUGINS

  SRAND
See Test2::Plugin::SRand.

This will set the random seed to today's date. You can provide an alternate seed with the "-srand" import option:

    use Test2::V0 -srand => 1234;

You can also disable this behavior:

    use Test2::V0 -no_srand => 1;

Note When srand is on (default) it can cause problems with things like File::Temp which will end up attempting the same "random" filenames for every test process started on a given day (or sharing the same seed).

  UTF8
See Test2::Plugin::UTF8.

This will set the file, and all output handles (including formatter handles), to utf8. This will turn on the utf8 pragma for the current scope.

This can be disabled using the "-no_utf8 => 1" or "-no_pragmas => 1" import arguments.

    use Test2::V0 -no_utf8 => 1;

  EXIT SUMMARY
See Test2::Plugin::ExitSummary.

This plugin has no configuration.

ENVIRONMENT VARIABLES
See Test2::Env for a list of meaningul environment variables.

API FUNCTIONS
See Test2::API for these

$ctx = context()
$events = intercept { ... }

TOOLS

  TARGET
See Test2::Tools::Target.

You can specify a target class with the "-target" import argument. If you do not provide a target then $CLASS and CLASS() will not be imported.

    use Test2::V0 -target => 'My::Class';

    print $CLASS;  # My::Class
    print CLASS(); # My::Class

Or you can specify names:

    use Test2::V0 -target => { pkg => 'Some::Package' };

    pkg()->xxx; # Call 'xxx' on Some::Package
    $pkg->xxx;  # Same

$CLASS
    Package variable that contains the target class name.

$class = CLASS()
    Constant function that returns the target class name.

  DEFER
