NAME

       Test::Builder::Module - Base class for test modules

SYNOPSIS

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

         my $CLASS = __PACKAGE__;

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

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

         1;

DESCRIPTION

       This is a superclass for Test::Builder-based modules.  It provides a handful of common
       functionality and a method of getting at the underlying Test::Builder object.

   Importing
       Test::Builder::Module is a subclass of Exporter which means your module is also a subclass
       of Exporter.  @EXPORT, @EXPORT_OK, etc...  all act normally.

       A few methods are provided to do the "use Your::Module tests => 23" part for you.

       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.

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

           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.

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

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

       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.

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

       See Test::More for an example of its use.

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

   Builder
       Test::Builder::Module provides some methods of getting at the underlying Test::Builder
       object.

       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.

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

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

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

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