.IX Title "Test::Pod 3"
.TH Test::Pod 3 "2010-04-26" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
Test::Pod \- check for POD errors in files
.SH "VERSION"
.IX Header "VERSION"
Version 1.44
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\f(CW\*(C`Test::Pod\*(C'\fR lets you check the validity of a \s-1POD\s0 file, and report
its results in standard \f(CW\*(C`Test::Simple\*(C'\fR fashion.
.PP
.Vb 2
\&    use Test::Pod tests => $num_tests;
\&    pod_file_ok( $file, "Valid POD file" );
.Ve
.PP
Module authors can include the following in a \fIt/pod.t\fR file and
have \f(CW\*(C`Test::Pod\*(C'\fR automatically find and check all \s-1POD\s0 files in a
module distribution:
.PP
.Vb 4
\&    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();
.Ve
.PP
You can also specify a list of files to check, using the
\&\f(CW\*(C`all_pod_files()\*(C'\fR function supplied:
.PP
.Vb 6
\&    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 ) );
.Ve
.PP
Or even (if you're running under Apache::Test):
.PP
.Vb 4
\&    use strict;
\&    use Test::More;
\&    eval "use Test::Pod 1.00";
\&    plan skip_all => "Test::Pod 1.00 required for testing POD" if $@;
.Ve
.PP
.Vb 5
\&    my @poddirs = qw( blib script );
\&    use File::Spec::Functions qw( catdir updir );
\&    all_pod_files_ok(
\&        all_pod_files( map { catdir updir, $_ } @poddirs )
\&    );
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Check \s-1POD\s0 files for errors or warnings in a test file, using
\&\f(CW\*(C`Pod::Simple\*(C'\fR to do the heavy lifting.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.Sh "pod_file_ok( FILENAME[, \s-1TESTNAME\s0 ] )"
.IX Subsection "pod_file_ok( FILENAME[, TESTNAME ] )"
\&\f(CW\*(C`pod_file_ok()\*(C'\fR will okay the test if the \s-1POD\s0 parses correctly.  Certain
conditions are not reported yet, such as a file with no pod in it at all.
.PP
When it fails, \f(CW\*(C`pod_file_ok()\*(C'\fR will show any pod checking errors as
diagnostics.
.PP
The optional second argument \s-1TESTNAME\s0 is the name of the test.  If it
is omitted, \f(CW\*(C`pod_file_ok()\*(C'\fR chooses a default test name \*(L"\s-1POD\s0 test
for \s-1FILENAME\s0\*(R".
.Sh "all_pod_files_ok( [@entries] )"
.IX Subsection "all_pod_files_ok( [@entries] )"
Checks all the files under \f(CW@entries\fR for valid \s-1POD\s0. It runs
\&\fIall_pod_files()\fR on directories and assumes everything else to be a file to
be tested. It calls the \f(CW\*(C`plan()\*(C'\fR function for you (one test for each file),
so you can't have already called \f(CW\*(C`plan\*(C'\fR.
.PP
If \f(CW@entries\fR is empty or not passed, the function finds all \s-1POD\s0 files in
files in the \fIblib\fR directory if it exists, or the \fIlib\fR directory if not. A
\&\s-1POD\s0 file is one that ends with \fI.pod\fR, \fI.pl\fR and \fI.pm\fR, or any file where
the first line looks like a shebang line.
.PP
If you're testing a module, just make a \fIt/pod.t\fR:
.PP
.Vb 4
\&    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();
.Ve
.PP
Returns true if all pod files are ok, or false if any fail.
.Sh "all_pod_files( [@dirs] )"
.IX Subsection "all_pod_files( [@dirs] )"
Returns a list of all the Perl files in \fI@dirs\fR and in directories below. If
no directories are passed, it defaults to \fIblib\fR if \fIblib\fR exists, or else
\&\fIlib\fR if not. Skips any files in \s-1CVS\s0, .svn, .git and similar directories. See
\&\f(CW%Test::Pod::ignore_dirs\fR for a list of them.
.PP
A Perl file is:
.IP "* Any file that ends in \fI.PL\fR, \fI.pl\fR, \fI.PL\fR, \fI.pm\fR, \fI.pod\fR, or \fI.t\fR." 4
.IX Item "Any file that ends in .PL, .pl, .PL, .pm, .pod, or .t."
.PD 0
.ie n .IP "* Any file that has a first line with a shebang and ""perl"" on it." 4
.el .IP "* Any file that has a first line with a shebang and ``perl'' on it." 4
.IX Item "Any file that has a first line with a shebang and perl on it."
.ie n .IP "* Any file that ends in \fI.bat\fR and has a first line with ""\-\-*\-Perl\-*\-\-"" on it." 4
.el .IP "* Any file that ends in \fI.bat\fR and has a first line with ``\-\-*\-Perl\-*\-\-'' on it." 4
.IX Item "Any file that ends in .bat and has a first line with --*-Perl-*-- on it."
.PD
.PP
The order of the files returned is machine\-dependent.  If you want them
sorted, you'll have to sort them yourself.
