Integration Tests with Kafka
Hello, everyone!
I’ve started learning for a technical interview involving the use of an API to send messages to a Kafka Cluster.
I’ve observed a limited number of examples for using Kafka with Elixir. Perhaps I should consider using umbrella projects? However, my main question is: How can I perform integration tests with a Kafka mock server to send and consume messages?
In other languages, for instance, I would use test-containers, but in Elixir, I’m uncertain about the equivalent approach.
I apologize if my questions seem straightforward; I’m relatively new to learning Elixir.
Thank you!

There is exactly zero problem bringing up a container for integration tests in Elixir as well, there’s nothing special about it, it’s still Docker + Compose in the end. 
As for Kafka, I believe Overview — brod v4.5.5 is the accepted way of doing it. It also has integration with GitHub - elixir-broadway/broadway: Concurrent and multi-stage data ingestion and data processing with Elixir · GitHub.
