This patch just fell through the cracks for me.
I had (wrongly) inferred that Andy might have had some lingering
reservations about this patch (that it was too contrived, might not be
useful to have tests for stuff like abs(), etc.).

Feel free to pull this into your series.

Looking over the code itself, I think this still looks valid and
stylistically correct with regard to KUnit.
I haven't gone and validated that it still compiles and runs just yet, though.
But if you do run into any problems, let me know and I can help send
you a fixed version.

Thanks for picking this up,
Daniel
