NAME

Test::WWW::Mechanize::CGIApp - Test::WWW::Mechanize for CGI::Application

SYNOPSIS

   # We're in a t/*.t test script...
   use Test::WWW::Mechanize::CGIApp;
 
   my $mech = Test::WWW::Mechanize::CGIApp->new;
 
   # test a class that uses CGI::Application calling semantics.
   # (in this case we'll new up an instance of the app and call
   # its ->run() method)
   #
   $mech->app("My::WebApp");
   $mech->get_ok("?rm=my_run_mode&arg1=1&arg2=42");
 
   # test a class that uses CGI::Application::Dispatch
   # to locate the run_mode
   # (in this case we'll just call the ->dispatch() class method).
   #
   my $dispatched_mech = Test::WWW::Mechanize::CGIApp->new;
   $dispatched_mech->app("My::DispatchApp");
   $mech->get_ok("/WebApp/my_run_mode?arg1=1&arg2=42");
 
   # create an anonymous sub that this class will use to
   # handle the request.
   #
   # this could be useful if you need to do something novel
   # after creating an instance of your class (e.g. the
   # fiddle_with_stuff() below) or maybe you have a unique
   # way to get the app to run.
   #
   my $custom_mech = Test::WWW::Mechanize::CGIApp->new;
   $custom_mech->app(
      sub {
        require "My::WebApp";
        my $app = My::WebApp->new();
        $app->fiddle_with_stuff();
        $app->run();
      });
   $mech->get_ok("?rm=my_run_mode&arg1=1&arg2=42");
 
   # at this point you can play with all kinds of cool
   # Test::WWW::Mechanize testing methods.
   is($mech->ct, "text/html");
   $mech->title_is("Root", "On the root page");
   $mech->content_contains("This is the root page", "Correct content");
   $mech->follow_link_ok({text => 'Hello'}, "Click on Hello");
   # ... and all other Test::WWW::Mechanize methods
 
 

DESCRIPTION

This package makes testing CGIApp based modules fast and easy. It takes advantage of Test::WWW::Mechanize to provide 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" );
 
 

For applications that inherit from CGI::Application it will handle requests by creating a new instance of the class and calling its "run" method. For applications that use CGI::Application::Dispatch it will call the "dispatch" class method. If neither of these options are the right thing, you can set a reference to a sub that will be used to handle the request.

This module supports cookies automatically.

CONSTRUCTOR

new

Behaves like, and calls, Test::WWW::Mechanize's "new" method. It optionally uses an ``app'' parameter (see below), any other parameters get passed to Test::WWW::Mechanize's constructor. Note that you can either pass the name of the CGI::Application into the constructor using the ``app'' parameter or set it later using the "app" method.
   use Test::WWW::Mechanize::CGIApp;
   my $mech = Test::WWW::Mechanize::CGIApp->new;
 
   # or
 
   my $mech = Test::WWW::Mechanize::CGIApp->new(app => 'TestApp');
 
 

METHODS

$mech->app($app_handler)

This method provides a mechanism for informing Test::WWW::Mechanize::CGIApp how it should go about executing your run_mode. If you set it to the name of a class, then it will load the class and either create an instance and ->run() it (if it's CGI::Application based), invoke the ->dispatch() method if it's CGI::Application::Dispatch based, or call the supplied anonymous subroutine and let it do all of the heavy lifting.
