NAME

CGI::Prototype::Mecha - test CGI::Prototype applications with WWW::Mechanize

SYNOPSIS

use CGI::Prototype::Mecha;
my $m = CGI::Prototype::Mecha->new(protoapp => 'My::App');

$m->get('http://mecha/');
ok $m->success, "fetched welcome page" or $m->diag_response;
like $m->content, qr/Select a task/, "welcome page content verified";

DESCRIPTION

WWW::Mechanize combined with Test::More is a great toolbench for testing a web application. But you need to have your code installed in the right location on a running server, and you can't poke behind the scenes to see if data structures or databases in your application are as they are expected to be after a particular web hit.

Enter CGI::Prototype::Mecha, a subclass of WWW::Mechanize.

Simply create a Mecha object, giving it the name of your CGI::Prototype-derived application class, and "visit" the magic URL of http://mecha/. Your application is fired up (loading the classes as needed), and you get a "response" as if it were being sent to the browser.

But, your object is in the same program as your test, so you can set environment variables to simulate auth success or control testing databases. Or even capture STDERR into a file to make sure that a particular error log value is or is not being written.

Methods

new

Extended from WWW::Mechanize. An additional protoapp parameter is understood, expecting a CGI::Prototype-derived application class (which should be located in the current @INC). Returns the mecha object.

simple_request

Extended from WWW::Mechanize (which inherits it directly from LWP::UserAgent. This is where the magic happens.

Note that visiting any URL that does not start with http://mecha/ is fatal. A future version may fall back to the original WWW::Mechanize, letting you test your app's outbound links properly.

As of version 0.20, even "input type=file" fields will be properly handled.

diag_response

A convenience method that dumps the result "as_string" via diag() from Test::More.

diag_links

A convenience method that dumps all the links (text/url) via diag().

diag_forms

A convenience method that dumps all the forms via diag().
