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


This documentation describes version 0.002.


     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' ], 


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.


Note: Subroutines in a package starting with an underscore are ignored. Therefore, do not include them in any list of expected subroutines.


   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.


   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.
