=head1 NAME
Test::HTML::Lint - Test::More-style wrapper around HTML::Lint
=head1 VERSION
Version 2.26
=cut
$VERSION = '2.26';
my $Tester = Test::Builder->new;
=head1 SYNOPSIS
use Test::HTML::Lint tests => 4;
my $table = build_display_table();
html_ok( $table, 'Built display table properly' );
=head1 DESCRIPTION
This module provides a few convenience methods for testing exception
based code. It is built with L<Test::Builder> and plays happily with
L<Test::More> and friends.
If you are not already familiar with L<Test::More> now would be the time
to go take a look.
=head1 EXPORT
C<html_ok>
=cut
@EXPORT = qw(
html_ok
html_fragment_ok
);
sub import {
my $self = shift;
my $pack = caller;
$Tester->exported_to($pack);
$Tester->plan(@_);
$self->export_to_level(1, $self, @EXPORT);
return;
}
=head2 html_ok( [$lint, ] $html, $name )
Checks to see if C<$html> is a valid HTML document, including checks
for having C<< <html> >>, C<< <head> >>, C<< <title>> >> and
C<< <body> >> tags.
If you're checking something that is only a fragment of an HTML document,
use C<html_fragment_ok()>.
If you pass an HTML::Lint object, C<html_ok()> will use that for its
settings.
my $lint = new HTML::Lint( only_types => STRUCTURE );
html_ok( $lint, $content, "Web page passes structural tests only" );
Otherwise, it will use the default rules.
html_ok( $content, "Web page passes ALL tests" );
Note that if you pass in your own HTML::Lint object, C<html_ok()>
will clear its errors before using it.
=cut
sub html_ok {
my $lint;
if ( ref($_[0]) eq 'HTML::Lint' ) {
$lint = shift;
$lint->newfile();
$lint->clear_errors();
}

my $nerr = scalar $lint->errors;
$ok = !$nerr;
$Tester->ok( $ok, $name );
if ( !$ok ) {
my $msg = 'Errors:';
$msg .= " $name" if $name;
$Tester->diag( $msg );
$Tester->diag( $_->as_string ) for $lint->errors;
}
}
return $ok;
}
=head2 html_fragment_ok( [$lint, ] $html, $name )
Checks that C<$fragment> is valid HTML, but not necessarily a valid
HTML document.
For example, this is a valid fragment, but not a valid HTML document:
<body>
<p>Lorem ipsum</p>
</body>
because it doesn't contain C<< <html> >> and C<< <head> >> tags. If you
want to check that it is a valid document, use C<html_ok()>.
If you pass an HTML::Lint object, C<html_fragment_ok()> will use that for its
settings.
my $lint = new HTML::Lint( only_types => STRUCTURE );
html_fragment_ok( $lint, $content, 'Web page passes structural tests only' );
Otherwise, it will use the default rules.
html_fragment_ok( $content, 'Fragment passes ALL tests' );
Note that if you pass in your own HTML::Lint object, C<html_fragment_ok()>
will clear its errors before using it.

# Ignore doc-level errors.

$msg .= " $name" if $name;
$Tester->diag( $msg );

}

=head1 BUGS
All bugs and requests are now being handled through GitHub.
https://github.com/petdance/html-lint/issues
DO NOT send bug reports to http://rt.cpan.org/ or http://code.google.com/
=head1 TO DO
There needs to be a C<html_table_ok()> to check that the HTML is a
self-contained, well-formed table, and then a comparable one for
C<html_page_ok()>.
If you think this module should do something that it doesn't do at the
moment please let me know.
=head1 ACKNOWLEDGEMENTS
Thanks to chromatic and Michael G Schwern for the excellent Test::Builder,
without which this module wouldn't be possible.
Thanks to Adrian Howard for writing Test::Exception, from which most of
this module is taken.
