In a previous blog we described how we used JUnit and Reflection to verify correct implementation of coding standards addressing Axon Upcaster consistency. We concluded that, although possible, it felt a bit like a hack because we had to change modifiers of Java variables defined as “private static final” resulting in Java security manager warnings. […]
In our last project we used a JUnit test to check consistency of all code concerned with Axon event upcasting. We think this is interesting as we basically unit test source code rather than class behavior. In this blog we describe how we implemented it and conclude with a short evaluation and we list alternative […]
This article explains how the concept of upcasting can be applied to an event-sourced model. Focusing on demultiplexing of events, a new feature in Axon 2.
