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


       # 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(@_);



     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.


     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.


     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

     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() is called by import().  It provides an oppor-
     tunity 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.


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


       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 previ-
     ously 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(@_);
