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().

WIDGET DESCRIPTION ^
