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().
