Releasing the Gen monad

Some time ago I wrote a piece about generating randomized instances of domain objects for unit and integration testing using a functional approach. Looking back at my past projects, I almost always used this approach to simplify existing and newly written tests in the codebases that I was working on. Of course, the implementation matured over the years as well. What started off as a very simplistic @FunctionalInterface became a well-tested Java-based implementation of the Gen monad.

Event-driven Microservices Conference 2019

Quite an interesting day finally came to an end. AxonIQ, which is the company behind the Axon framework and server, hosted their annually conference in Amsterdam.
