名前¶

Test::Builder::Module - テストモジュールのための基底クラス

概要¶

  # Emulates Test::Simple
  package Your::Module;

  my $CLASS = __PACKAGE__;

  use base 'Test::Builder::Module';
  @EXPORT = qw(ok);

  sub ok ($;$) {
      my $tb = $CLASS->builder;
      return $tb->ok(@_);
  }
  
  1;

説明¶

これは Test::Builder ベースのモジュールのスーパークラスです。 基となる Test::Builder オブジェクトを使う、便利な共通機能とメソッドを 提供します。

インポート¶

Test::Builder::Module は Exporter のサブクラスなので、あなたのモジュールも Exporter のサブクラスになります。 @EXPORT, @EXPORT_OK などは通常通り動作します。

use Your::Module tests = 23> 部分を行うためのいくつかのメソッドが 提供されています。

import¶

Test::Builder::Module provides an import() method which acts in the same basic way as Test::More's, setting the plan and controlling exporting of functions and variables. This allows your module to set the plan independent of Test::More. (TBT)

All arguments passed to import() are passed onto Your::Module->builder->plan() with the exception of import =>[qw(things to import)]. (TBT)

    use Your::Module import => [qw(this that)], tests => 23;

says to import the functions this() and that() as well as set the plan to be 23 tests. (TBT)

import() also sets the exported_to() attribute of your builder to be the caller of the import() function. (TBT)

Additional behaviors can be added to your import() method by overriding import_extra(). (TBT)

import_extra¶

    Your::Module->import_extra(\@import_args);

import_extra() is called by import(). It provides an opportunity for you to add behaviors to your module based on its import list. (TBT)

Any extra arguments which shouldn't be passed on to plan() should be stripped off by this method. (TBT)

See Test::More for an example of its use. (TBT)

NOTE This mechanism is VERY ALPHA AND LIKELY TO CHANGE as it feels like a bit of an ugly hack in its current form. (TBT)

ビルダー¶

Test::Builder::Module は、基となる Test::Builder オブジェクトを得るための メソッドを提供します。

builder¶

  my $builder = Your::Class->builder;

This method returns the Test::Builder object associated with Your::Class. It is not a constructor so you can call it as often as you like. (TBT)

This is the preferred way to get the Test::Builder object. You should not get it via Test::Builder->new as was previously recommended. (TBT)

The object returned by builder() may change at runtime so you should call builder() inside each function rather than store it in a global. (TBT)

  sub ok {
      my $builder = Your::Class->builder;

      return $builder->ok(@_);
  }
