dogtail How to control "Software Updater" or "pirut" program?

["Charles Tan" <tzq emails bjut edu cn>]

hi, guys,
I'm a python rookie, and I want to automatically test some GUI
programs, for example, the gnome Software Updater(or pirut). My idea
is very simple, that use a program to control the other programs being
tested.
And I found dogtail is very good at testing gtk+ based applications.
But it could not test pirut, which is written in python, because it
couldn't sniff the buttons and menus inside the pirut.
I've read some code of the pirut and it used gtk, gtk.glade to
generate the windows. I don't know why pirut could not sniff the
widgets in the "pirut" program. Could some kindly guys explain the
reason? Or tell me an alternative method to automatically test
"pirut"?
Thank you in advance.
Regards,
