I get "unable to open device '/class/block/sd*'" for
any '/class/block/sd*' name. The same for "/block/sd*[0-9]":

# udevadm test /block/sdc1
run_command: calling: test
udevadm_test: version 130
[...]
parse_file: reading '/lib/udev/rules.d/50-udev-default.rules' as rules
file
[...]
parse_file: reading '/etc/udev/rules.d/99-local.rules' as rules file
unable to open device '/block/sdc1'
udev_unref: context 0x8064008 released

Only names like '/block/sdX' seems to go beyond the parse_file part:

with udev 130:
