This could be used in more tests, for example test/internet/test-dns.js.

@silverwind Are you referring to this part of the file?

node/test/parallel/test-dns.js

Lines 214 to 221 in 9cb390d

	const invalidHost = 'fasdfdsaf';
	assert.throws(() => {
	dns.lookupService(invalidHost, 0, common.mustNotCall());
	}, common.expectsError({
	code: 'ERR_INVALID_OPT_VALUE',
	type: TypeError,
	message: `The value "${invalidHost}" is invalid for option "host"`
	}));

@lpinca yes, that's another example, but I was refering to the file in internet tests, for example:

node/test/internet/test-dns.js

Line 391 in 9cb390d

const req = dns.lookup('does.not.exist', 4, function(err, ip, family) {

node/test/internet/test-dns.js

Line 514 in 9cb390d

const req = dns.lookup('nosuchhostimsure', function(err) {

@silverwind I guess the comment was for @tniessen.
