it's not allowed to pass the partitions argument when the type is non-partitioned, so need to set this as a pointer

Is it possible to add a test for it?

@RobertIndie There are no tests for the namespaces(and other modules) at all, we may need a PIP to setup the tests structure first

I don't think we need a PIP for that. We can utilize the existing testing framework. Seems that you can just create a test go file and write the test. I have created a PR to show how to do it: #1152

Then you can refer to these scripts to run the tests: https://github.com/apache/pulsar-client-go/tree/master/scripts . It will run in the CI: https://github.com/apache/pulsar-client-go/blob/master/.github/workflows/ci.yml#L50
