NAME ^

CGI::Test::Page - Abstract represention of an HTTP reply content

SYNOPSIS ^

 # Deferred class, only heirs can be created
 # $page holds a CGI::Test::Page object

 use CGI::Test;

 ok 1, $page->is_ok;
 ok 2, $page->user ne '';    # authenticated access

 my $ctype = $page->content_type;
 ok 3, $ctype eq "text/plain";

 $page->delete;

DESCRIPTION ^

The CGI::Test::Page class is deferred. It is an abstract representation of an HTTP reply content, which would be displayed on a browser, as a page. It does not necessarily hold HTML content.

Here is an outline of the class hierarchy tree, with the leading CGI::Test:: string stripped for readability, and a trailing * indicating deferred clases:

    Page*
      Page::Error
      Page::Real*
        Page::HTML
        Page::Other
        Page::Text

Those classes are constructed as needed by CGI::Test. You must always call delete on them to break the circular references if you care about reclaiming unused memory.

INTERFACE ^

This is the interface defined at the CGI::Test::Page level. Each subclass may add further specific features, but the following is available to the whole hierarchy:

content_type

The MIME content type, along with parameters, as it appeared in the headers. For instance, it can be:

        text/html; charset=ISO-8859-1

Don't assume it to be just text/html though. Use something like:

        ok 1, $page->content_type =~ m|^text/html\b|;

in your regression tests, which will match whether there are parameters following the content type or not.

delete

Breaks circular references to allow proper reclaiming of unused memory. Must be the last thing to call on the object before forgetting about it.

error_code

The error code. Will be 0 to mean OK, but otherwise HTTP error codes are used, as described by HTTP::Status.

forms

Returns a list reference containing all the CGI forms on the page, as CGI::Test::Form objects. Will be an empty list for anything but CGI::Test::Page::HTML, naturally.

form_count

The amount of forms held in the forms list.

is_error

Returns true when the page indicates an HTTP error.

is_ok

Returns true when the page is not the result of an HTTP error.

server

Returns the server object that returned the page. Currently, this is the CGI::Test object, but it might change one day. In any case, this is the place where GET/POST requests may be addresed.

user

The authenticated user that requested this page, or undef if no authentication was made.
