[PySide] Unit testing modal dialogs

[Aaron Richiger]

Hello Diego

I ran into the same issues some time ago and couldn't solve it... But 
now, I tried again and found a way to get references of the objects you 
mentioned. Please check the following example to see how it works:

It shows both, modal dialogs and message boxes. For testing, it's always 
the same approach I guess:

- Start a QTimer.singleShot() before triggering the message box or 
dialog, give it enough time to start the dialog and a callable where you 
grab the active widget
- Then trigger the message box or dialog
- The callable is executed automatically a few milliseconds later. Grab 
the active dialog and perform some actions or assert some properties on 
it as usual in tests...

I think, there is not too much overhead like this, it's just always one 
line (...singleShot...) before performing the action that executes the 
dialog.

I hope, it helps!
Have a nice evening!
