Dist::Zilla::Util::Test::KENTNL(3pm)

"dztest"

Creates a "Dist::Zilla::Util::Test::KENTNL" object.

This is a much more sane approach to testing than "test_config"

test_config

This is pretty much why this module exists. Its a little perverse, but makes testing WAY easier.

  my $plugin = test_config({
    dist_root => 'corpus/dist/DZT',
    ini       => [
      'GatherDir',
      [ 'Prereqs' => { 'Test::Simple' => '0.88' } ],
    ],
    post_build_callback => sub {
        my $config = shift;
        # Handy place to put post-construction test code.
        die $config->{error} if $config->{error};
    },
    find_plugin => 'SomePluginName'
  });

Additionally, you can add this section

  callback => {
    method => 'metadata',
    args   => [],
    code   => sub {
      my $data = shift;
      print "Errors ( if any ) $data->{error} ";
      dump  $data->{response}; # response from ->metadata
      $data->{instance}->doMorestuffbyhand();
      # ok( .... 'good place for a test!' )
    },
  }

Generally, I find it easier to do 1-off function wrappers, i.e.:

  sub make_plugin {
    my @args = @_;
    return test_config({
        dist_root => 'corpus/dist/DZT',
        ini => [
          'GatherDir',
          [ 'Prereqs' => {'Test::Simple' => '0.88' } ],
          [ 'FakePlugin' => {@args } ],
        ],
        post_build_callback => sub {
          my $config = shift;
          die $config->{error} if $config->{error};
        },
        find_plugin => 'FakePlugin',
    });
  }

Which lets us do

  ok( make_plugin( inherit_version => 1 )->inherit_version , 'inherit_verion = 1 propagates' );

parameters

  my $foo = test_config({
      dist_root => 'Some/path'    # optional, strongly recommended.
      ini       => [              # optional, strongly recommended.
          'BasicPlugin',
          [ 'AdvancedPlugin' => { %pluginargs }],
      ],
      build    => 0/1              # works fine as 0, 1 tells it to call the ->build() method.
      post_build_callback => sub {
        my ( $conf )  = shift;
        $conf->{error}    # any errors that occured during construction/build
        $conf->{instance} # the constructed instance
        # this is called immediately after construction, do what you will with this.
        # mostly for convenience
      },
      find_plugin => 'Some::Plugin::Name', # makes test_config find and return the plugin that matched that name instead of
                                           # the config instance
      callback => {                        # overrides the return value of find_plugin if it is called
        method => 'method_to_call',
        args   => [qw( hello world )],
        code   => sub {
          my ($conf) = shift;
          $conf->{plugin}   # the constructed plugin instance
          $conf->{error}    # any errors discovered when calling ->method( args )
          $conf->{instance} # the zilla instance
          $conf->{response} # the return value of ->method( args )
          # mostly just another convenience of declarative nature.
          return someValueHere # this value will be returned by test_config
        }
      },
  });
