NAME

       Test::WWW::Mechanize - Testing-specific WWW::Mechanize subclass

VERSION

       Version 1.42

SYNOPSIS

       Test::WWW::Mechanize is a subclass of WWW::Mechanize that incorporates features for web
       application testing.  For example:

           use Test::More tests => 5;
           use Test::WWW::Mechanize;

           my $mech = Test::WWW::Mechanize->new;
           $mech->get_ok( $page );
           $mech->base_is( 'http://petdance.com/', 'Proper <BASE HREF>' );
           $mech->title_is( 'Invoice Status', "Make sure we're on the invoice page" );
           $mech->text_contains( 'Andy Lester', 'My name somewhere' );
           $mech->content_like( qr/(cpan|perl)\.org/, 'Link to perl.org or CPAN' );

       This is equivalent to:

           use Test::More tests => 5;
           use WWW::Mechanize;

           my $mech = WWW::Mechanize->new;
           $mech->get( $page );
           ok( $mech->success );
           is( $mech->base, 'http://petdance.com', 'Proper <BASE HREF>' );
           is( $mech->title, 'Invoice Status', "Make sure we're on the invoice page" );
           ok( index( $mech->content( format => 'text' ), 'Andy Lester' ) >= 0, 'My name somewhere' );
           like( $mech->content, qr/(cpan|perl)\.org/, 'Link to perl.org or CPAN' );

       but has nicer diagnostics if they fail.

       Default descriptions will be supplied for most methods if you omit them. e.g.

           my $mech = Test::WWW::Mechanize->new;
           $mech->get_ok( 'http://petdance.com/' );
           $mech->base_is( 'http://petdance.com/' );
           $mech->title_is( 'Invoice Status' );
           $mech->content_contains( 'Andy Lester' );
           $mech->content_like( qr/(cpan|perl)\.org/ );

       results in

           ok - Got 'http://petdance.com/' ok
           ok - Base is 'http://petdance.com/'
           ok - Title is 'Invoice Status'
           ok - Text contains 'Andy Lester'
           ok - Content is like '(?-xism:(cpan|perl)\.org)'

CONSTRUCTOR

   new( %args )
       Behaves like, and calls, WWW::Mechanize's "new" method.  Any parms passed in get passed to
       WWW::Mechanize's constructor.

       You can pass in "autolint => 1" to make Test::WWW::Mechanize automatically run HTML::Lint
       after any of the following methods are called. You can also pass in an HTML::Lint object
       like this:

           my $lint = HTML::Lint->new( only_types => HTML::Lint::Error::STRUCTURE );
           my $mech = Test::WWW::Mechanize->new( autolint => $lint );

       ·   get_ok()

       ·   post_ok()

       ·   submit_form_ok()

       ·   follow_link_ok()

       ·   click_ok()

       This means you no longer have to do the following:

           my $mech = Test::WWW::Mechanize->new();
           $mech->get_ok( $url, 'Fetch the intro page' );
           $mech->html_lint_ok( 'Intro page looks OK' );

       and can simply do

           my $mech = Test::WWW::Mechanize->new( autolint => 1 );
           $mech->get_ok( $url, 'Fetch the intro page' );

       The "$mech->get_ok()" only counts as one test in the test count.  Both the main IO
       operation and the linting must pass for the entire test to pass.

       You can control autolint on the fly with the "autolint" method.

METHODS: HTTP VERBS

   $mech->get_ok($url, [ \%LWP_options ,] $desc)
       A wrapper around WWW::Mechanize's get(), with similar options, except the second argument
       needs to be a hash reference, not a hash. Like well-behaved "*_ok()" functions, it returns
       true if the test passed, or false if not.

       A default description of "GET $url" is used if none if provided.

   $mech->head_ok($url, [ \%LWP_options ,] $desc)
       A wrapper around WWW::Mechanize's head(), with similar options, except the second argument
       needs to be a hash reference, not a hash. Like well-behaved "*_ok()" functions, it returns
       true if the test passed, or false if not.

       A default description of "HEAD $url" is used if none if provided.

   $mech->post_ok( $url, [ \%LWP_options ,] $desc )
       A wrapper around WWW::Mechanize's post(), with similar options, except the second argument
       needs to be a hash reference, not a hash. Like well-behaved "*_ok()" functions, it returns
       true if the test passed, or false if not.

       A default description of "POST to $url" is used if none if provided.

   $mech->put_ok( $url, [ \%LWP_options ,] $desc )
       A wrapper around WWW::Mechanize's put(), with similar options, except the second argument
       needs to be a hash reference, not a hash. Like well-behaved "*_ok()" functions, it returns
       true if the test passed, or false if not.

       A default description of "PUT to $url" is used if none if provided.

   $mech->submit_form_ok( \%parms [, $desc] )
       Makes a "submit_form()" call and executes tests on the results.  The form must be found,
       and then submitted successfully.  Otherwise, this test fails.

       %parms is a hashref containing the parms to pass to "submit_form()".  Note that the parms
       to "submit_form()" are a hash whereas the parms to this function are a hashref.  You have
       to call this function like:

           $mech->submit_form_ok( {
                   form_number => 3,
                   fields      => {
                       answer => 42
                   },
               }, 'now we just need the question'
           );

       As with other test functions, $desc is optional.  If it is supplied then it will display
       when running the test harness in verbose mode.

       Returns true value if the specified link was found and followed successfully.  The
       HTTP::Response object returned by submit_form() is not available.

   $mech->follow_link_ok( \%parms [, $desc] )
       Makes a "follow_link()" call and executes tests on the results.  The link must be found,
       and then followed successfully.  Otherwise, this test fails.

       %parms is a hashref containing the parms to pass to "follow_link()".  Note that the parms
       to "follow_link()" are a hash whereas the parms to this function are a hashref.  You have
       to call this function like:

           $mech->follow_link_ok( {n=>3}, 'looking for 3rd link' );

       As with other test functions, $desc is optional.  If it is supplied then it will display
       when running the test harness in verbose mode.

       Returns a true value if the specified link was found and followed successfully.  The
       HTTP::Response object returned by follow_link() is not available.

   click_ok( $button[, $desc] )
       Clicks the button named by $button.  An optional $desc can be given for the test.

METHODS: CONTENT CHECKING

   $mech->html_lint_ok( [$desc] )
       Checks the validity of the HTML on the current page.  If the page is not HTML, then it
       fails.  The URI is automatically appended to the $desc.

       Note that HTML::Lint must be installed for this to work.  Otherwise, it will blow up.

   $mech->title_is( $str [, $desc ] )
       Tells if the title of the page is the given string.

           $mech->title_is( 'Invoice Summary' );

   $mech->title_like( $regex [, $desc ] )
       Tells if the title of the page matches the given regex.

           $mech->title_like( qr/Invoices for (.+)/

   $mech->title_unlike( $regex [, $desc ] )
       Tells if the title of the page matches the given regex.

           $mech->title_unlike( qr/Invoices for (.+)/

   $mech->base_is( $str [, $desc ] )
       Tells if the base of the page is the given string.

           $mech->base_is( 'http://example.com/' );

   $mech->base_like( $regex [, $desc ] )
       Tells if the base of the page matches the given regex.

           $mech->base_like( qr{http://example.com/index.php?PHPSESSID=(.+)});

   $mech->base_unlike( $regex [, $desc ] )
       Tells if the base of the page matches the given regex.

           $mech->base_unlike( qr{http://example.com/index.php?PHPSESSID=(.+)});

   $mech->content_is( $str [, $desc ] )
       Tells if the content of the page matches the given string

   $mech->content_contains( $str [, $desc ] )
       Tells if the content of the page contains $str.

   $mech->content_lacks( $str [, $desc ] )
       Tells if the content of the page lacks $str.

   $mech->content_like( $regex [, $desc ] )
       Tells if the content of the page matches $regex.

   $mech->content_unlike( $regex [, $desc ] )
       Tells if the content of the page does NOT match $regex.

   $mech->text_contains( $str [, $desc ] )
       Tells if the text form of the page's content contains $str.

       When your page contains HTML which is difficult, unimportant, or unlikely to match over
       time as designers alter markup, use "text_contains" instead of "content_contains".

        # <b>Hi, <i><a href="some/path">User</a></i>!</b>
        $mech->content_contains('Hi, User'); # Fails.
        $mech->text_contains('Hi, User'); # Passes.

       Text is determined by calling "$mech->text()".  See "content" in WWW::Mechanize.

   $mech->text_lacks( $str [, $desc ] )
       Tells if the text of the page lacks $str.

   $mech->text_like( $regex [, $desc ] )
       Tells if the text form of the page's content matches $regex.

   $mech->text_unlike( $regex [, $desc ] )
       Tells if the text format of the page's content does NOT match $regex.

   $mech->has_tag( $tag, $text [, $desc ] )
       Tells if the page has a $tag tag with the given content in its text.

   $mech->has_tag_like( $tag, $regex [, $desc ] )
       Tells if the page has a $tag tag with the given content in its text.

   $mech->followable_links()
       Returns a list of links that Mech can follow.  This is only http and https links.

   $mech->page_links_ok( [ $desc ] )
       Follow all links on the current page and test for HTTP status 200

           $mech->page_links_ok('Check all links');

   $mech->page_links_content_like( $regex [, $desc ] )
       Follow all links on the current page and test their contents for $regex.

           $mech->page_links_content_like( qr/foo/,
             'Check all links contain "foo"' );

   $mech->page_links_content_unlike( $regex [, $desc ] )
       Follow all links on the current page and test their contents do not contain the specified
       regex.

           $mech->page_links_content_unlike(qr/Restricted/,
             'Check all links do not contain Restricted');

   $mech->links_ok( $links [, $desc ] )
       Follow specified links on the current page and test for HTTP status 200.  The links may be
       specified as a reference to an array containing WWW::Mechanize::Link objects, an array of
       URLs, or a scalar URL name.

           my @links = $mech->find_all_links( url_regex => qr/cnn\.com$/ );
           $mech->links_ok( \@links, 'Check all links for cnn.com' );

           my @links = qw( index.html search.html about.html );
           $mech->links_ok( \@links, 'Check main links' );

           $mech->links_ok( 'index.html', 'Check link to index' );

   $mech->link_status_is( $links, $status [, $desc ] )
       Follow specified links on the current page and test for HTTP status passed.  The links may
       be specified as a reference to an array containing WWW::Mechanize::Link objects, an array
       of URLs, or a scalar URL name.

           my @links = $mech->followable_links();
           $mech->link_status_is( \@links, 403,
             'Check all links are restricted' );

   $mech->link_status_isnt( $links, $status [, $desc ] )
       Follow specified links on the current page and test for HTTP status passed.  The links may
       be specified as a reference to an array containing WWW::Mechanize::Link objects, an array
       of URLs, or a scalar URL name.

           my @links = $mech->followable_links();
           $mech->link_status_isnt( \@links, 404,
             'Check all links are not 404' );

   $mech->link_content_like( $links, $regex [, $desc ] )
       Follow specified links on the current page and test the resulting content of each against
       $regex.  The links may be specified as a reference to an array containing
       WWW::Mechanize::Link objects, an array of URLs, or a scalar URL name.

           my @links = $mech->followable_links();
           $mech->link_content_like( \@links, qr/Restricted/,
               'Check all links are restricted' );

   $mech->link_content_unlike( $links, $regex [, $desc ] )
       Follow specified links on the current page and test that the resulting content of each
       does not match $regex.  The links may be specified as a reference to an array containing
       WWW::Mechanize::Link objects, an array of URLs, or a scalar URL name.

           my @links = $mech->followable_links();
           $mech->link_content_unlike( \@links, qr/Restricted/,
             'No restricted links' );

   $mech->stuff_inputs( [\%options] )
       Finds all free-text input fields (text, textarea, and password) in the current form and
       fills them to their maximum length in hopes of finding application code that can't handle
       it.  Fields with no maximum length and all textarea fields are set to 66000 bytes, which
       will often be enough to overflow the data's eventual recepticle.

       There is no return value.

       If there is no current form then nothing is done.

       The hashref $options can contain the following keys:

       ·   ignore

           hash value is arrayref of field names to not touch, e.g.:

               $mech->stuff_inputs( {
                   ignore => [qw( specialfield1 specialfield2 )],
               } );

       ·   fill

           hash value is default string to use when stuffing fields.  Copies of the string are
           repeated up to the max length of each field.  E.g.:

               $mech->stuff_inputs( {
                   fill => '@'  # stuff all fields with something easy to recognize
               } );

       ·   specs

           hash value is arrayref of hashrefs with which you can pass detailed instructions about
           how to stuff a given field.  E.g.:

               $mech->stuff_inputs( {
                   specs=>{
                       # Some fields are datatype-constrained.  It's most common to
                       # want the field stuffed with valid data.
                       widget_quantity => { fill=>'9' },
                       notes => { maxlength=>2000 },
                   }
               } );

           The specs allowed are fill (use this fill for the field rather than the default) and
           maxlength (use this as the field's maxlength instead of any maxlength specified in the
           HTML).

   $mech->lacks_uncapped_inputs( [$comment] )
       Executes a test to make sure that the current form content has no text input fields that
       lack the "maxlength" attribute, and that each "maxlength" value is a positive integer.
       The test fails if the current form has such a field, and succeeds otherwise.

       Returns an array containing all text input fields in the current form that do not specify
       a maximum input length.  Fields for which the concept of input length is irrelevant, and
       controls that HTML does not allow to be capped (e.g. textarea) are ignored.

       The inputs in the returned array are descended from HTML::Form::Input.

       The return is true if the test succeeded, false otherwise.

METHODS: MISCELLANEOUS

   $mech->autolint( [$status] )
       Without an argument, this method returns a true or false value indicating whether autolint
       is active.

       When passed an argument, autolint is turned on or off depending on whether the argument is
       true or false, and the previous autolint status is returned.  As with the autolint option
       of "new", $status can be an HTML::Lint object.

       If autolint is currently using an HTML::Lint object you provided, the return is that
       object, so you can change and exactly restore autolint status:

           my $old_status = $mech->autolint( 0 );
           ... operations that should not be linted ...
           $mech->autolint( $old_status );

   $mech->grep_inputs( \%properties )
       grep_inputs() returns an array of all the input controls in the current form whose
       properties match all of the regexes in $properties.  The controls returned are all
       descended from HTML::Form::Input.

       If $properties is undef or empty then all inputs will be returned.

       If there is no current page, there is no form on the current page, or there are no submit
       controls in the current form then the return will be an empty array.

           # get all text controls whose names begin with "customer"
           my @customer_text_inputs =
               $mech->grep_inputs( {
                   type => qr/^(text|textarea)$/,
                   name => qr/^customer/
               }
           );

   $mech->grep_submits( \%properties )
       grep_submits() does the same thing as grep_inputs() except that it only returns controls
       that are submit controls, ignoring other types of input controls like text and checkboxes.

   $mech->scrape_text_by_attr( $attr, $attr_value [, $html ] )
   $mech->scrape_text_by_attr( $attr, $attr_regex [, $html ] )
       Returns an array of strings, each string the text surrounded by an element with attribute
       $attr of value $value.  You can also pass in a regular expression.  If nothing is found
       the return is an empty list.  In scalar context the return is the first string found.

       If passed, $html is scraped instead of the current page's content.

   scrape_text_by_id( $id [, $html ] )
       Finds all elements with the given id attribute and pulls out the text that that element
       encloses.

       In list context, returns a list of all strings found. In scalar context, returns the first
       one found.

       If $html is not provided then the current content is used.

   $mech->scraped_id_is( $id, $expected [, $msg] )
       Scrapes the current page for given ID and tests that it matches the expected value.

TODO

       Add HTML::Tidy capabilities.
