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(@_);
         }
