Test::Pod - check for POD errors in files

Version 1.20

    $Header: /home/cvs/test-pod/Pod.pm,v 1.10 2004/06/23 05:35:27 andy Exp $

CWTest::Pod lets you check the validity of a POD file, and report its results in standard CWTest::Simple fashion.

    use Test::Pod;
    plan tests => $num_tests;
    pod_file_ok( $file, "Valid POD file" );

Module authors can include the following in a t/pod.t file and have CWTest::Pod automatically find and check all POD files in a module distribution:

    use Test::More;
    eval "use Test::Pod 1.00";
    plan skip_all => "Test::Pod 1.00 required for testing POD" if $@;
    all_pod_files_ok();

You can also specify a list of files to check, using the CWall_pod_files() function supplied:

    use strict;
    use Test::More;
    eval "use Test::Pod 1.00";
    plan skip_all => "Test::Pod 1.00 required for testing POD" if $@;
    my @poddirs = qw( blib script );
    all_pod_files_ok( all_pod_files( @poddirs ) );

Or even (if you're running under Apache::Test):

    use strict;
    use Test::More;
    eval "use Test::Pod 1.00";
    plan skip_all => "Test::Pod 1.00 required for testing POD" if $@;

    my @poddirs = qw( blib script );
    use File::Spec::Functions qw( catdir updir );
    all_pod_files_ok(
        all_pod_files( map { catdir updir, $_ } @poddirs )
    );

Check POD files for errors or warnings in a test file, using CWPod::Simple to do the heavy lifting.

CWpod_file_ok() will okay the test if the POD parses correctly. Certain conditions are not reported yet, such as a file with no pod in it at all.

When it fails, CWpod_file_ok() will show any pod checking errors as diagnostics.

The optional second argument TESTNAME is the name of the test. If it is omitted, CWpod_file_ok() chooses a default test name POD test for FILENAME.

Checks all the files in CW@files for valid POD. It runs all_pod_files() on each file/directory, and calls the CWplan() function for you (one test for each function), so you can't have already called CWplan.

If CW@files is empty or not passed, the function finds all POD files in the blib directory if it exists, or the lib directory if not. A POD file is one that ends with .pod, .pl and .pm, or any file where the first line looks like a shebang line.

If you're testing a module, just make a t/pod.t:

    use Test::More;
    eval "use Test::Pod 1.00";
    plan skip_all => "Test::Pod 1.00 required for testing POD" if $@;
    all_pod_files_ok();

Returns true if all pod files are ok, or false if any fail.

Returns a list of all the Perl files in $dir and in directories below. If no directories are passed, it defaults to blib if blib exists, or else lib if not. Skips any files in CVS or .svn directories.

A Perl file is:

* Any file that ends in .PL, .pl, .pm, .pod or .t.

The order of the files returned is machine-dependent. If you want them sorted, you'll have to sort them yourself.

Note: This function is deprecated. Use pod_file_ok() going forward.

pod_ok parses the POD in filename and returns one of five symbolic constants starting from the top of this list:

        NO_FILE       Could not find the file
        NO_POD        File had no pod directives
        POD_ERRORS    POD had errors
        POD_WARNINGS  POD had warnings
        POD_OK        No errors or warnings

pod_ok will okay the test if you don't specify any expected result and it finds no errors or warnings, or if you specify what you expect and it finds that condition. For instance, if you can live with warnings,

        pod_ok( $file, POD_WARNINGS );

When it fails, pod_ok will show any pod checking errors.

The optional third argument NAME is the name of the test which pod_ok passes through to Test::Builder. Otherwise, it chooses a default test name POD test for FILENAME.

STUFF TO DO

Note the changes that are being made.

Note that you no longer can test for no pod.
