      The following code will execute against the primary instead of the secondary:

      const url = 'mongodb://user:password@localhost:27018,localhost:27017,localhost:27019/test?replicaSet=replset';

MongoClient.connect(url, { readPreference: ReadPreference.SECONDARY }, (err, client) => {
  const cursor = db.collection('test').find({});
  cursor.count().then(count => console.log("count: " + count));
});

      It appears that the cursor does not respect the read preference of its parents.
