Quite right. The chickens and the eggs.

In my case (with the XMidiGenerator and XMidiSerializer) I am trying to
confirm that a "round trip" has been successful, so for me this test is
ideal. After generating XML *from* my binary file I subsequently serialize
to a binary file which I hope is exactly the same as the original binary

Also, I find that once I have finally succeeded in getting some code to work
it's good to have a test to confirm that if I make changes to it later, my
code is *still* working! So indeed, even if the expected output may have
been generated with the component I want to test, at least I can tell if the
component continues to behave consistently after I make changes.
