#pod This routine returns a string that could be used to populate a simple

#pod

#pod
#pod This becomes C<[PluginMoniker / PluginName]>
#pod
#pod = C<[ "PluginMoniker", { ... } ]>
#pod
#pod = C<[ "PluginMoniker", "PluginName", { ... } ]>
#pod
#pod These use the given hashref as the parameters inside the section, with the same

=head1 NAME
Test::DZil - tools for testing Dist::Zilla plugins
=head1 VERSION
version 6.025
=head1 DESCRIPTION
Test::DZil provides routines for writing tests for Dist::Zilla plugins.
=head1 PERL VERSION
This module should work on any version of perl still receiving updates from
the Perl 5 Porters. This means it should work on any version of perl released
in the last two to three years. (That is, if the most recently released
version is v5.40, then this module should work on both v5.40 and v5.38.)
Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased. The version may be increased
for any reason, and there is no promise that patches will be accepted to lower
the minimum required perl.
=head1 FUNCTIONS
=head2 Builder
=head2 Minter
my $tzil = Builder->from_config(...);
These return class names that subclass L<Dist::Zilla::Dist::Builder> or
L<Dist::Zilla::Dist::Minter>, respectively, with the L<Dist::Zilla::Tester>
behavior added.
=head2 is_filelist
is_filelist( \@files_we_have, \@files_we_want, $desc );
This test assertion compares two arrayrefs of filenames, taking care of slash
normalization and sorting. C<@files_we_have> may also contain objects that
do L<Dist::Zilla::Role::File>.
=head2 is_yaml
is_yaml( $yaml_string, $want_struct, $comment );
This test assertion deserializes the given YAML string and does a
C<L<cmp_deeply|Test::Deep/cmp_deeply>>.
=head2 is_json
is_json( $json_string, $want_struct, $comment );
This test assertion deserializes the given JSON string and does a
C<L<cmp_deeply|Test::Deep/cmp_deeply>>.
=head2 dist_ini
my $ini_text = dist_ini(\%root_config, @plugins);
This routine returns a string that could be used to populate a simple
F<dist.ini> file. The C<%root_config> gives data for the "root" section of the
configuration. To provide a line multiple times, provide an arrayref. For
example, the root section could read:
{
name => 'Dist-Sample',
author => [
'J. Smith <jsmith@example.com>',
'Q. Smith <qsmith@example.com>',
],
}
The root section is optional.
Plugins can be given in a few ways:
=over 4
=item C<"PluginMoniker">
=item C<[ "PluginMoniker" ]>
These become C<[PluginMoniker]>
=item C<[ "PluginMoniker", "PluginName" ]>
This becomes C<[PluginMoniker / PluginName]>
=item C<[ "PluginMoniker", { ... } ]>
=item C<[ "PluginMoniker", "PluginName", { ... } ]>
These use the given hashref as the parameters inside the section, with the same
semantics as the root section.
=back
=head2 simple_ini
This behaves exactly like C<dist_ini>, but it merges any given root config into
a starter config, which means that you can often skip any explicit root config.
The starter config may change slightly over time, but is something like this:
{
name => 'DZT-Sample',
abstract => 'Sample DZ Dist',
version => '0.001',
author => 'E. Xavier Ample <example@example.org>',
license => 'Perl_5',
copyright_holder => 'E. Xavier Ample',
