That's not what I was asking about (a bunch of message tests with various
parameters). Your current version essentially tests nothing.

You should call UpdateLayeredWindowIndirect with a buch of differnt parameters,
and check what message sequence they produce and how they change window state.

See dlls/user32/tests/msg.c how to create a message test.
