Test::HTML::W3C3pm

Usage

  use Test::HTML::W3C tests => $test_count;
  # or
  use Test::HTML::W3C 'show_detail';
  # or when using both
  use Test::HTML::W3C tests => $test_count, 'show_detail';
  is_valid_markup($my_html_scalar);
  is_valid_file("/path/to/my/file.html");
  is_valid("http://example.com");
  # Get the underlying WebService:;Validator::W3C::HTML object
  my $validator = validator();

Overview

The purpose of this module is to provide a wrapper around the W3C that works with the Test::More testing framework.

Abuse

Please keep in mind that the W3C validation pages and services are a shared resource. If you plan to do many many tests, please consider using your own installation of the validation programs, and then use your local install by modifying the local validtor:

  my $v = validator();
  $v->validator_uri($my_own_validator);

See the documentation for WebService:;Validator::W3C::HTML and the W3C's site at http://validator.w3.org/ for details

validator();

Description: Returns the underlying WebService::Validator::HTML::W3C object

Parameters: None.

Returns: $validator

plan();

Description: Access to the underlying "plan" method provided by Test::Builder.

Parameters: As per Test::Builder

is_valid_markup($markup[, $name]);

Description: is_valid_markup tests whether the text in the provided scalar value correctly validates according to the W3C specifications. This is useful if you have markup stored in a scalar that you wish to test that you might get from using LWP or WWW::Mechanize for example...

Parameters: $markup, a scalar containing the data to test, $name, an optional descriptive test name.

Returns: None.

is_valid_file($path[, $name]);

Description: is_valid_file works the same way as is_valid_markup, except that you can specify the text to validate with the path to a filename. This is useful if you have pregenerated all your HTML files locally, and now wish to test them.

Parameters: $path, a scalar, $name, an optional descriptive test name.

Returns: None.

is_valid($url[, $name]);

Description: is_valid, again, works very similarly to the is_valid_file and is_valid_file, except you specify a document that is already online with its URL. This can be useful if you wish to periodically test a website or webpage that dynamically changes over time for example, like a blog or a wiki, without first saving the html to a file using your browswer, or a utility such as wget.

Parameters: $url, a scalar, $name, an optional descriptive test name.

Returns: None.

diag_html($url);

Description: If you want to display the actual errors reported by the service for a particular test, you can use the diag_html function. Please note that you must have imported 'show_detail' for this to work properly.

  use Test::HTML::W3C 'show_detail';
  is_valid_markup("<html></html">, "My simple test") or diag_html();

Parameters: $url, a scalar.

Returns: None.
