For GUI testing, you might want to have a look at Dogtail and/or LDTP.

The third argument is of type Gtk2::Gdk::ModifierType, which is a flags
value.  That means it can also be empty, which is achieved by using
undef or [].

You can either run the main loop and then stop it from some callback via
Gtk2->main_quit, or you can try running just enough main loop iterations:

  while (Gtk2->events_pending ()) {
    Gtk2->main_iteration ();
  }
