Actually I don't know how to test the display with QTest :/
(I've tested it by running custom executables)

I've seen that `qtest_init_internal` sets `-display none`
so I imagine there's no way to test the display visually.

It seems to me that I can't use a qdev property (to access
the DM163 buffer and check its content) either since there's
no `visit_type_*` for arrays.

I could technically access all the elements in the array 
(returning a different element each time in the getter for
example), but that seems sketchy.


In short, how can I provide a test or an example?

Best regards,

Ines
