SYNOPSIS

12           use Test::More tests => 3;
13           use Test::API;
14
15           require_ok( 'My::Package' );
16
17           public_ok ( 'My::Package', @names );
18
19           import_ok ( 'My::Package',
20               export    => [ 'foo', 'bar' ],
21               export_ok => [ 'baz', 'bam' ],
22           );
23
24           class_api_ok( 'My::Class', @methods );

DESCRIPTION

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

USAGE

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

54       Therefore, do not include any of these in a list of expected
55       subroutines.
56
57   public_ok
58         public_ok( $package, @names );
59
60       This function checks that all of the @names provided are available
61       within the $package namespace and that *only* these subroutines are
62       available.  This means that subroutines imported from other modules
63       will cause this test to fail unless they are explicitly included in
64       @names.
65
66   class_api_ok
67         class_api_ok( $class, @names );
68
69       A variation of "public_ok" for object-oriented modules. Allows
70       superclasses to fill in "missing" subroutines, but "extra" methods
71       provided by superclasses will not cause the test to fail.
72
73   import_ok
74         import_ok ( $package, %spec );
75
76       This function checks that $package correctly exports an expected list
77       of subroutines and *only* these subroutines.  The %spec generally
78       follows the style used by [Exporter], but in lower case:
79
80         %spec = (
81           export    => [ 'foo', 'bar' ],  # exported automatically
82           export_ok => [ 'baz', 'bam' ],  # optional exports
83         );
84
85       For "export_ok", the test will check for public functions not listed in
86       "export" or "export_ok" that can be imported and will fail if any are
87       found.
