=head1 NAME

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

=head1 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 L<Test2::Suite> itself.

=head1 NAMING, USING, DEPENDING

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

As new C<V#> modules are released old ones I<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 L<Test2::Suite> as your modules dep, instead list the specific bundle, or
tools and plugins you use directly in your metadata.

=head1 SYNOPSIS

    use Test2::V0;

    ok(1, "pass");

    ...

    done_testing;

=head1 RESOLVING CONFLICTS WITH MOOSE

    use Test2::V0 '!meta';

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

=head2 TAGS

=over 4

=item :DEFAULT

The following are both identical:

    use Test2::V0;

    use Test2::V0 ':DEFAULT';

=back

=head2 RENAMING ON IMPORT

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

This bundle uses L<Importer> for exporting, as such you can use any arguments
it accepts.

Explanation:

=over 4

=item '!ok'

Do not export C<ok()>

=item ok => {-as => 'my_ok'}

Actually, go ahead and import C<ok()> but under the name C<my_ok()>.

=back

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

=head1 PRAGMAS

All of these can be disabled via individual import arguments, or by the
C<-no_pragmas> argument.

    use Test2::V0 -no_pragmas => 1;

=head2 STRICT

L<strict> is turned on for you. You can disable this with the C<-no_strict> or
C<-no_pragmas> import arguments:

    use Test2::V0 -no_strict => 1;

=head2 WARNINGS

L<warnings> are turned on for you. You can disable this with the
C<-no_warnings> or C<-no_pragmas> import arguments:

    use Test2::V0 -no_warnings => 1;

=head2 UTF8

This is actually done via the L<Test2::Plugin::UTF8> plugin, see the
L</PLUGINS> section for details.

B<Note:> C<< -no_pragmas => 1 >> will turn off the entire plugin.

=head1 PLUGINS

=head2 SRAND

See L<Test2::Plugin::SRand>.

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

    use Test2::V0 -srand => 1234;

=head2 UTF8

See L<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 C<< -no_utf8 => 1 >> or C<< -no_pragmas => 1 >>
import arguments.

    use Test2::V0 -no_utf8 => 1;

=head2 EXIT SUMMARY

See L<Test2::Plugin::ExitSummary>.

This plugin has no configuration.

=head1 API FUNCTIONS

=back

=head1 TOOLS

=head2 TARGET

See L<Test2::Tools::Target>.

You can specify a target class with the C<-target> import argument. If you do
not provide a target then C<$CLASS> and C<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
