Yes and no.. Yes closing the figure will destroy this property. However 
if the test fails then you won't get to the piece of code to close the 
figure.. I hadn't thought of that before. How this is handled elsewhere 
in Octave, as each test is run in its own try/catch block is to do 
something like

%!test
%! figure (1)
%! set (gcf, "visibility", "off")

%!test
%! sombrero
%! colorbar
%! shading interp
%! shading flat
%! shading facted
%! assert (true)

%!test
%! ## Yet another graphics test

%!test
%! close (1)
