Hi @zookzook
First of all thank you for all your work! elixir-mongodb-driver is very handful :)
I have question about tests - Are all tests shall pass? Some of them failing locally for me:

Finished in 70.0 seconds (2.2s async, 67.7s sync)
264 tests, 43 failures, 3 excluded

[LKlemens]

I found that I cannot connect to test mongo replica.
Did I do sth wrong?

Steps:
1. export PATH=/usr/local/Cellar/mongodb-community/7.0.2/bin/:$PATH
2.  ulimit -S -n 2048 ## in case of Mac OS X
3. mlaunch init --setParameter enableTestCommands=1 --replicaset --name "rs_1"

I will look into it tomorrow. Maybe the replica-set is not able to communicate. Please check if the servers are listening to the specified ports.

[LKlemens]

yep, there are listening - I can connect it using url e.g. mongodb://localhost:27017
But connection is useless because I cannot do anything because of errors

 elixir-mongodb-driver git:(master) ✗ mongosh mongodb://localhost:27017

For mongosh info see: https://docs.mongodb.com/mongodb-shell/

What prints "rs.config()"

[LKlemens]

test> rs.config()
MongoServerError: no replset config has been received

Did you try do it by yourself? Do tests work for you?

[zookzook]

Yes, this should work. That means, that your Replica-Set is not configured. Try this:

rs.initiate({_id: “rs_1”, members: [{_id: 0, host: “127.0.0.1:27017"}, {_id: 1, host: “127.0.0.1:27018”}, {_id: 2, host: “127.0.0.1:27019"]}

[LKlemens]

I checked it, and indeed it works now, thanks!
I will add it to README.
One test fails anyway - could you check if it works for you?

  test/mongo/read_preferences_test.exs:58

Mongo instances exits during tests, and I have to manually start it again and again.
Have you encountered such behavior?

[LKlemens]

After deleting those line it started passing
73
81
But I have no idea why ;/ Missing some tags setup?

[zookzook]

You need to setup the tags in this case.

[LKlemens]

I've just read the test docs 🤦
But that should be done automatically in setup section, to avoid setting it up manually before running that one test, wdyt?
