Guess you refer to test code for bootmeth-rauc. Honestly, no idea.

I just came to notice that there now is an official way, so bumped the
U-Boot version to 2025.10 in a customer project. And stumbled upon some
details, hence the fixes. I've got some more in the workqueue (mostly
improve printouts what went wrong and extending documentation a bit),
but none of it will be ready before 2025.10 release. Needs polish and
testing. I'll send them in hopefully in time for 2025.11 merge window.

A quick look in test/boot/bootmeth.c shows some tests for extlinux,
efi, vbe simple. I guess the list check would be expandable for rauc,
too. The fixed numbering might need some massage, but surely doable.

But the real thing is to test the boot flow itself, and especially the
switchover and fallback handling. Which in principle is comparable for
all methods, but differ in detail. I can see you already wrote quite
extensive test cases here, respect for that! However I haven't looked
into them yet. But pretty sure this will be a task of days, not hours.

While I'm happy to assist here, I realistically won't find the time to
act as the main implementor.
But maybe Martin Schwan already has some snippets prepared here ?
Or we even might pull in the RAUC developers, to some extent at least ?
I know their codebase includes an outstanding amount of test coverage,
so there is appreciation for testing at least.

Best regards,
  Andreas
