[TIP] PyQt testing with nose

[Paul Hildebrandt]

Noah,

We are also looking at automated GUI testing for PyQt.  There are two 
open source tools that I've found:
    * LDTP - http://ldtp.freedesktop.org
    * Dogtail - https://fedorahosted.org/dogtail/

 Both tools rely on hooks into the Accessibility library.  That doesn't 
currently work with Qt.  There is on going work to make them work but
 it's probably a couple months out.  I've emailed Nagappen, of LDTP 
fame, and he said:
> If the GUI application is written using gnome (gtk widget) / Mozilla 
> (XUL) / Java (Swing interface) / OpenOffice, then you can access with 
> LDTP. Currently there is a work going on to use accessibility layer in

I am pretty sure Nagappen is on the list so maybe he will chime in.

Mark Doffman is doing the accessibility work.  Here is some 
corrispondence I've gotten from him:

Mark's work looks pretty good but he just needs time or help to complete it.

So in summary, we've played with LDTP and I think it's pretty cool but 
it can't work with PyQt, right now.  We are looking at Squish 
(http://www.froglogic.com/) to do some automated testing in the time being.
