DESCRIPTION
PSGI is a specification to decouple web server environments from web application framework
code. Test::WWW::Mechanize is a subclass of WWW::Mechanize that incorporates features for
web application testing. The Test::WWW::Mechanize::PSGI module meshes the two to allow
easy testing of PSGI applications.
Testing web applications has always been a bit tricky, normally requiring starting a web
server for your application and making real HTTP requests to it. This module allows you to
test PSGI web applications but does not require a server or issue HTTP requests. Instead,
it passes the HTTP request object directly to PSGI. Thus you do not need to use a real
hostname: "http://localhost/" will do. However, this is optional. The following two lines
of code do exactly the same thing:
$mech->get_ok('/action');
$mech->get_ok('http://localhost/action');
This makes testing fast and easy. Test::WWW::Mechanize provides functions for common web
testing scenarios. For example:
$mech->get_ok( $page );
$mech->title_is( "Invoice Status", "Make sure we're on the invoice page" );
$mech->content_contains( "Andy Lester", "My name somewhere" );
$mech->content_like( qr/(cpan|perl)\.org/, "Link to perl.org or CPAN" );
An alternative to this module is Plack::Test.
CONSTRUCTOR
new
Behaves like, and calls, WWW::Mechanize's "new" method. You should pass in your
application:
my $mech = Test::WWW::Mechanize::PSGI->new(
app => sub {
my $env = shift;
return [ 200, [ 'Content-Type' => 'text/plain' ], ['Hello World'] ],;
},
);
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:
$agent->submit_form_ok(
form_number => 3,
fields => {
username => 'mungo',
password => 'lost-and-alone',
}
}, "looking for 3rd form" );
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->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->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).
