mind making these const instead of var?

I copied that from another test. Should I make a PR that changes this for every test where it isn't already the new way?

I believe the plan is to update them as we go. But in general, all new tests should use const wherever possible

var assert = require('assert');
var net = require('net');

var client = net.connect({
port: common.PORT + 1,

I'm not sure which port to use here, it simply should produce an ECONNREFUSED error when connecting.

localPort: common.PORT,
localAddress: '127.0.0.1'

Instead of hard coding the IP address, can you use common.localhostIPv4.

instead of having the onErrorCalled, you could wrap the callback to the error event in common.mustCall().

You could then remove the process.on('exit') listener too

assert.equal(err.localPort, common.PORT);
assert.equal(err.localAddress, '127.0.0.1');
onErrorCalled = true;
});

process.on('exit', function() {
assert.ok(onErrorCalled);
});
