This is what I do

I have ca. 190 test cases on which I run my software and compare the md5 sums of the resulting PDF. If they are not the same, I create a PNG for every page and compare visually with imagemagick.

The trick is to remove all random stuff from the PDF (like ID generation or such).

This takes about 3 seconds on the M1 Pro laptop. I think this is very much okay.
