You probably gave a non-existant sysfs path to the command (see /sys).
To get the sysfs device path for a device node do:
$ udevinfo -q path -n /dev/input/event4
/class/input/input4/event4
Then you use the returned sysfs device path to get the sysfs attributes:
$ udevinfo -a -p /class/input/input4/event4
[...]
Of course you can combine the two commands:
$ udevinfo -a -p $(udevinfo -q path -n /dev/input/event4)
[...]
For udevtest you also have to use the sysfs path -- not the device node:
$ udevtest /class/input/event4
main: looking at device '/class/input/input4/event4' from subsystem 'input'
udev_rules_get_name: rule applied, 'event4' becomes 'input/mx1000'
run_program: 'inputdev.sh event4'
run_program: '/lib/udev/inputdev.sh' returned with status 0
create_node: creating device node '/dev/input/mx1000', major = '13', minor =
'68', mode = '0660', uid = '0', gid = '0'
main: run: 'socket:/org/kernel/udev/monitor'
main: run: 'udev_run_hotplugd input'
main: run: 'udev_run_devd input'
