=head1 NAME

Test::Selenium::Remote::Driver

=head1 DESCRIPTION

A subclass of L<Selenium::Remote::Driver>.  which provides useful testing
functions.

This is an I<experimental> addition to the Selenium::Remote::Driver
distribution, and some interfaces may change.

=head1 Methods

=head2 new ( %opts )

This will create a new Test::Selenium::Remote::Driver object, which subclasses
L<Selenium::Remote::Driver>.  This subclass provides useful testing
functions.  It is modeled on L<Test::WWW::Selenium>.

Environment vars can be used to specify options to pass to
L<Selenium::Remote::Driver>. ENV vars are prefixed with C<TWD_>.
( After the old fork name, "Test::WebDriver" )

Set the Selenium server address with C<$TWD_HOST> and C<$TWD_PORT>.

Pick which browser is used using the  C<$TWD_BROWSER>, C<$TWD_VERSION>,
C<$TWD_PLATFORM>, C<$TWD_JAVASCRIPT>, C<$TWD_EXTRA_CAPABILITIES>.

See L<Selenium::Driver::Remote> for the meanings of these options.

=cut

sub BUILDARGS {
    my ( $class, %p ) = @_;

    }

    $p{webelement_class}   //= 'Test::Selenium::Remote::WebElement';
    return \%p;
}

=head2 server_is_running( $host, $port )

Returns true if a Selenium server is running.  The host and port
parameters are optional, and default to C<localhost:4444>.

Environment vars C<TWD_HOST> and C<TWD_PORT> can also be used to
determine the server to check.

    return ( $host, $port )
      if IO::Socket::INET->new(
        PeerAddr => $host,
        PeerPort => $port,
      );
    return;

   $twd->find_element_ok( $search_target [,$finder, $desc ] );

if none passed.

=head1 NOTES

This module was forked from Test::WebDriver 0.01.

For Best Practice - I recommend subclassing Test::Selenium::Remote::Driver for your application,
and then refactoring common or app specific methods into MyApp::WebDriver so that
your test files do not have much duplication.  As your app changes, you can update
