Shouldn't "d3ddm.Format" just be "D3DFMT_A8R8G8B8" here, since the
test is using create_device()?

Given the nature of this test, we'd probably want to retrieve
"screen_width" and "screen_height" with EnumDisplaySettingsW() and
ENUM_REGISTRY_SETTINGS, and perhaps also make sure they match the
current settings before running any tests.

This looks fairly complicated, but in the end you just need two
display modes that satisfy a couple of conditions. I suspect this code
could be simplified a fair bit. Of course that probably also applies
to test_reset() where this looks borrowed from.
