NAME

       Test::API - Test a list of subroutines provided by a module

VERSION

       version 0.005

SYNOPSIS

           use Test::More tests => 3;
           use Test::API;

           require_ok( 'My::Package' );

           public_ok ( 'My::Package', @names );

           import_ok ( 'My::Package',
               export    => [ 'foo', 'bar' ],
               export_ok => [ 'baz', 'bam' ],
           );

           class_api_ok( 'My::Class', @methods );

DESCRIPTION

       This simple test module checks the subroutines provided by a module.  This is useful for
       confirming a planned API in testing and ensuring that other functions aren't
       unintentionally included via import.

USAGE

       Note: Subroutines starting with an underscore are ignored, as are a number of other
       methods not intended to be called directly by end-users.

         import unimport bootstrap

         AUTOLOAD BUILD BUILDARGS CLONE CLONE_SKIP DESTROY DEMOLISH

         TIESCALAR TIEARRAY TIEHASH TIEHANDLE

         FETCH STORE UNTIE FETCHSIZE STORESIZE POP PUSH SHIFT UNSHIFT SPLICE
         DELETE EXISTS EXTEND CLEAR FIRSTKEY NEXTKEY PRINT PRINTF WRITE
         READLINE GETC READ CLOSE BINMODE OPEN EOF FILENO SEEK TELL SCALAR

         MODIFY_REF_ATTRIBUTES MODIFY_SCALAR_ATTRIBUTES MODIFY_ARRAY_ATTRIBUTES
         MODIFY_HASH_ATTRIBUTES MODIFY_CODE_ATTRIBUTES MODIFY_GLOB_ATTRIBUTES
         MODIFY_FORMAT_ATTRIBUTES MODIFY_IO_ATTRIBUTES

         FETCH_REF_ATTRIBUTES FETCH_SCALAR_ATTRIBUTES FETCH_ARRAY_ATTRIBUTES
         FETCH_HASH_ATTRIBUTES FETCH_CODE_ATTRIBUTES FETCH_GLOB_ATTRIBUTES
         FETCH_FORMAT_ATTRIBUTES FETCH_IO_ATTRIBUTES

       Therefore, do not include any of these in a list of expected subroutines.

   public_ok
         public_ok( $package, @names );

       This function checks that all of the @names provided are available within the $package
       namespace and that *only* these subroutines are available.  This means that subroutines
       imported from other modules will cause this test to fail unless they are explicitly
       included in @names.

   class_api_ok
         class_api_ok( $class, @names );

       A variation of "public_ok" for object-oriented modules. Allows superclasses to fill in
       "missing" subroutines, but "extra" methods provided by superclasses will not cause the
       test to fail.

   import_ok
         import_ok ( $package, %spec );

       This function checks that $package correctly exports an expected list of subroutines and
       *only* these subroutines.  The %spec generally follows the style used by [Exporter], but
       in lower case:

         %spec = (
           export    => [ 'foo', 'bar' ],  # exported automatically
           export_ok => [ 'baz', 'bam' ],  # optional exports
         );

       For "export_ok", the test will check for public functions not listed in "export" or
       "export_ok" that can be imported and will fail if any are found.
