As a suggestion:

To test the actual error it would be best to rewrite this to e.g.,:

fs.readdir(__filename, { withFileTypes: true }, common.expectsError({
  message: 'FOOBAR',
  name: 'ErrorName',
  ...
});

@BridgeAR the error is actually passed within the fs.readdir callback, how about:

fs.readdir(__filename, {
  withFileTypes: true
}, common.mustCall((err) => {
  assert.throws(
    () => { throw err; },
    {
      code: 'ENOTDIR',
      name: 'Error',
      message: `ENOTDIR: not a directory, scandir '${__filename}'`
    }
  );
}));

Right, sorry, I made a mistake when writing the example. I just updated it.
