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

SYNOPSIS
         # 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;

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 controling 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(@_);
         }
