I have a lot of testcases for GetObjectA/W. I will commit my GDI32 tests 
soon (next hour probably, after some cleanup).
The patch jimtabor referred to didn't even change any functionality 
except the GDI_OBJECT_TYPE_METADC case, wich I can provide a testcase for.
Please RTFC ;-)

examples:
MSDN says GetObject returns a LOGFONT, but it returnes different things 
depending on what you specify as count. More investigation is needed, 
but jimtabor has done some basics on that. Still missing: sizes not 
matching one of the structures. In those cases the structures get copied 
partly. The return value will be the count of bytes copied.

Same goes for brushes. The structure will be copied only as far as the 
count value specifies. But the return value will always be sizeof(LOGBRUSH)

all other types will return 0 and not copy anything if the buffer size 
is smaller than the structure.
...
Have a look at the gdi32_test.. and privide more tests.

Atm all my tests succeed, except some font tests, because sizes 
inbetween the structures are not handled and extlogpen, wich is not 
implemeted at all in ros.
