Let’s create a system test for Popyka (a system designed to capture database changes and publish them to Kafka), emphasizing a black-box approach, treating Popyka as a whole system and focusing on verifying its functionality end to end.

In this post, we’ll explore some technical aspects of constructing a lightweight Python-based CDC system. However, the core focus here is on the techniques that unlock rapid iteration and efficiency, particularly when navigating significant uncertainty. We’ll use PostgreSql and Kafka.
