NAME
    Test::Glade - a simple way to test Gtk2::GladeXML-based apps

SYNOPSIS
      use Test::Glade tests => 2;

      my $glade_xml = 'interface.glade';
      has_widget( $glade_xml, {
        name => 'main_window',
        type => 'GtkWindow',
        properties => {
          title => 'Test Application',
          type => 'GTK_WINDOW_TOPLEVEL',
          resizable => 1,
        },
      } );

      has_widget( $glade_xml, {
        type => 'GtkButton',
        properties => {label => 'Press me!'},
        signals => {clicked => 'button_pressed_handler'},
      } );

DESCRIPTION
    GUIs are notoriously difficult to test. Historically this was well
    deserved as the available perl GUI toolkits did not encourage separation
    of the view and controller layers. The introduction of the Glade GUI
    designer and Gtk2::GladeXML changed that by segregating user interface
    and logical components (into GladeXML and Perl files respectively).

    Users who avoid creating GUI elements from within their application
    logic can now test each layer separately with appropriate tools. The
    Perl logic can be verified with standard unit tests and this module
    provides a way to inspect and verify the GladeXML UI specification. You
    can confirm that a given widget exists, that it has the correct label
    and other attributes, that it will be correctly placed in the interface
    and that it will respond to signals as expected.

TEST METHODS
    has_widget($glade_file, $widget_desc, $test_name)
        Search for a widget in a GladeXML file. $widget is a hash reference
        of widget attributes. See "WIDGET DESCRIPTION" for more information.

OO METHODS
    If you have large GladeXML files, or want to perform many tests on each
    one, it might be faster to use the object oriented interface. Files are
    only parsed once, instead of once for each test.

    Test::Glade->new(file => $gladexml_file)
        Create a new Test::Glade object, passing in an optional GladeXML
        file.

    $test->load($gladexml_file)
        Load in a new GladeXML file.

    $test->widgets
        Return a list of all widgets in the file. See "WIDGET METHODS" for
        more information.

    $test->find_widget($widget_desc)
        Find and return widget. Takes $widget_desc in the same format as
        has_widget().
