Dist::Zilla::Util::Test::KENTNL::dztest - Shared dist testing logic for easy dzil things

VERSION

version 1.001001

SYNOPSIS

  use Test::More;
  use Test::DZil qw( simple_ini );
  use Dist::Zilla::Util::Test::KENTNL qw( dztest );

  my $test = dztest;

  ## utility method.
  $test->add_file( 'dist.ini', simple_ini( .... ));

  ## build the dist
  # 1x subtest
  $test->build_ok;

  ## assert prereqs are identical to the hash
  ## extracting them from distmeta
  # 1x subtest
  $test->prereqs_deeply( { } );

  ## Test for specific log messages by regex
  # 1x subtest
  #  - tests there are messages
  #  - each regex must match a message
  my @list = (
    [ $regex, $indepdent_reason ],
    [ $regex ],
  );
  $test->has_messages( $reason, \@list );

  ## Test for any deep structure addressed
  ## By a Data::DPath expression
  # 1x subtest
  #   - asserts the expression returns a result
  #   - compares the structure against the expected one.
  $test->meta_path_deeply(
      '/author/*/[1]',
      [ 'E. Xavier Ample <example@example.org>' ],
      'The 1st author is the example author emitted by simple_ini'
  );

  ## Test for a file existing on the build side
  ## and return it if it exists.
  my $file = $test->test_has_built_file('dist.ini');

METHODS

add_file

Add a file to the scratch directory to be built.

  # ->add_file( $path, $string );
  # ->add_file( \@path, $string );
  $test->add_file('dist.ini', simple_ini() );
  $test->add_file('lib/Foo.pm', $content );
  $test->add_file([ 'lib','Foo.pm' ], $content );

build_ok

Build the dist safely, and report ok if the dist builds ok, spewing file listings via note

BAIL_OUT is triggered if any of add_file don't arrive in the intended location.

prereqs_deeply

Demand distmeta prereqs exactly match those specified.

  $test->prereqs_deeply( { hash } );

This is just a more memorable version of

  $test->meta_path_deeply('/prereqs/', { });

has_messages

Test that there are messages, and all the given rules match messages.

  $test->has_messages( 'Some descriptor', [
     [ $regex, $description ],
     [ $regex, $description ],
  ]);

meta_path_deeply

  $test->meta_path_deeply( $expression, $expected_data, $reason );

Uses $expression as a Data::DPath expression to pick a LIST of nodes from distmeta, and compare that LIST vs $expected_data

  # Matches only the first author.
  $test->meta_path_deeply('/author/*/[1]', ['SomeAuthorName <wadef@wath>'], $reason );

  # Matches all authors
  $test->meta_path_deeply('/author/*/*', ['SomeAuthorName <wadef@wath>','Author2', ..], $reason );

test_has_built_file

Test ( as in, Test::More::ok ) that a file exists in the dzil build output directory.

Also returns it if it exists.

  $test->test_has_built_file('dist.ini');  # ok/fail

  my $object = test->test_has_built_file('dist.ini'); # ok/fail + return

source_file

Re-fetch content added with add_file.

You probably want built_file.

  $test->source_file( $path  );
  $test->source_file( \@path );

Returns undef if the file does not exist.

  if ( my $content = $test->source_file('dist.ini') ) {
    print $content->slurp_raw;
  }

configure

Construct the internal builder object.

  $test->configure;

safe_configure

Construct the internal builder object safely. Returns exceptions or undef.

  if( $test->configure ) { say "configure failed" }

safe_build

Ensure the distribution is built safely, returns exceptions or undef.

  if ( $test->safe_build ) {
    say "Failed build";
  }

built_file

Returns the named file if it exists in the build, undef otherwise.

  my $file = $test->built_file('dist.ini');

note_tempdir_files

Recursively walk tempdir and note its contents.

note_builddir_files

Recursively walk builddir(output) and note its contents.

has_message

Assert there are messages, and this single message exists:

  $test->has_message( $regex, $description );
