NAME

Test::Pod::Coverage - Check for pod coverage in your distribution.

VERSION

Version 1.08

SYNOPSIS

Checks for POD coverage in files for your distribution.

    use Test::Pod::Coverage tests=>1;
    pod_coverage_ok( "Foo::Bar", "Foo::Bar is covered" );

Can also be called with Pod::Coverage parms.

    use Test::Pod::Coverage tests=>1;
    pod_coverage_ok(
        "Foo::Bar",
        { also_private => [ qr/^[A-Z_]+$/ ], },
        "Foo::Bar, with all-caps functions as privates",
    );

The Pod::Coverage parms are also useful for subclasses that don't re-document the parent class's methods. Here's an example from Mail::SRS.

    pod_coverage_ok( "Mail::SRS" ); # No exceptions
    # Define the three overridden methods.
    my $trustme = { trustme => [qr/^(new|parse|compile)$/] };
    pod_coverage_ok( "Mail::SRS::DB", $trustme );
    pod_coverage_ok( "Mail::SRS::Guarded", $trustme );
    pod_coverage_ok( "Mail::SRS::Reversable", $trustme );
    pod_coverage_ok( "Mail::SRS::Shortcut", $trustme );

Alternately, you could use Pod::Coverage::CountParents, which always allows a subclass to reimplement its parents' methods without redocumenting them. For example:

    my $trustparents = { coverage_class => 'Pod::Coverage::CountParents' };
    pod_coverage_ok( "IO::Handle::Frayed", $trustparents );

(The "coverage_class" parameter is not passed to the coverage class with other parameters.)

If you want POD coverage for your module, but don't want to make Test::Pod::Coverage a prerequisite for installing, create the following as your t/pod-coverage.t file:

    use Test::More;
    eval "use Test::Pod::Coverage";
    plan skip_all => "Test::Pod::Coverage required for testing pod coverage" if $@;
    plan tests => 1;
    pod_coverage_ok( "Pod::Master::Html");

Finally, Module authors can include the following in a t/pod-coverage.t file and have "Test::Pod::Coverage" automatically find and check all modules in the module distribution:

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

FUNCTIONS

All functions listed below are exported to the calling namespace.

all_pod_coverage_ok( [$parms, ] $msg )

Checks that the POD code in all modules in the distro have proper POD coverage.

If the $parms hashref if passed in, they're passed into the "Pod::Coverage" object that the function uses. Check the Pod::Coverage manual for what those can be.

The exception is the "coverage_class" parameter, which specifies a class to use for coverage testing. It defaults to "Pod::Coverage".

pod_coverage_ok( $module, [$parms, ] $msg )

Checks that the POD code in $module has proper POD coverage.

If the $parms hashref if passed in, they're passed into the "Pod::Coverage" object that the function uses. Check the Pod::Coverage manual for what those can be.

The exception is the "coverage_class" parameter, which specifies a class to use for coverage testing. It defaults to "Pod::Coverage".

all_modules( [@dirs] )

Returns a list of all modules in $dir and in directories below. If no directories are passed, it defaults to blib if blib exists, or lib if not.

Note that the modules are as "Foo::Bar", not "Foo/Bar.pm".

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