NAME
    TAP::Parser::SourceHandler::Validator::W3C::HTML - validate HTML content

SYNOPSIS
     $ prove --source Validator::W3C::HTML http://example.com/some/page.html /path/to/some/file.html

DESCRIPTION
    Unit testing is awesome. App::Prove is awesome. HTML validation is
    awesome. Thus, the Validator::W3C::HTML SourceHandler was born.

    This SourceHandler provides TAP::Harness with TAP output generated as
    the result of HTML validation via the W3C validator. Both remote URIs
    and local HTML files are supported depending upon the type of source
    passed to the harness.

    If the source is a file with a .html or .htm extension or a file which
    contains text matching /html/i in the first line, then the source will
    be handled by this SourceHandler as raw HTML content.

    If the source is an HTTP or HTTPS URI, the source will be handled by
    this SourceHandler via <WWW::Robot>. When operating in URI mode, a few
    extra options are available. See below for configuration.

CONFIGURATION
    Configuration is done via the environment as is pretty common with perl
    testing. The supported configuration options are as follows:

    TEST_W3C_HTML_CRAWL (default: no)
        When in URI mode, crawl the site and recursively test all URIs below
        the hierarchy of the root URI.

    TEST_W3C_HTML_VALIDATOR_URI (default: http://validator.w3.org/check)
        The location of the W3C validator instance you wish to use. Please
        do not use the default if you're going to be using the validator for
        any volume.

    TEST_W3C_HTML_TIMEOUT (default: 5)
        The timeout for the LWP::UserAgent instance used by WWW::Robot.

    TEST_W3C_HTML_CHILDREN (default: no)
        When recursively crawling a site, use a Test::Builder child for each
        URI. This indents the TAP output for each URI, but can be less
        readable when using non-TAP formatters such as JUnit.

    Any environment variables beginning with TEST_W3C_HTML_SPIDER_ will be
    interpreted as attributes to be passed on to the WWW::Robot instance
    after stripping the leading portion.

CAVEATS
    This is my first experience with TAP::Harness. TAP::Harness is quite
    abstract and I am probably abusing it horribly. Please let me know if
    you have any suggestions for improvement.
