This command
test `cat /dev/null` != 1
expands after command substitution to a command with two arguments:
test != 1
That gets a complaint from test.
If you add double quotes around the backquotes, then the following two commands are equivalent:
test "`cat /dev/null`" != 1
test "" != 1
...and they give the desired "true" result, because there are three arguments, the first of which is a null string.
