Actually, we don't endorse the usage of the accessibility interfaces for 
testing. They are primarily designed to help people with various disabilities, 
so they might not expose what is actually on the screen.

Both squish and kd executor (to my knowledge) use startup hooks to inject an 
in-process hook for testing purposes, which gives access to all 
objects/widgets and all their properties, not only the subset that's exposed 
through QAccessible.
