Fitness Functions for Your Architecture

Fitness functions are an essential part of evolutionary architectures – and they can also bring desired structures and properties to legacy code bases, step by step. But how do they look like in practice? What kinds of fitness do they check and assert?

After a general introduction to fitness functions we'll do a deep dive into some concrete examples, covering use cases for common architectural patterns. We'll see examples in Java code, based on ArchUnit and jMolecules. But the basic ideas and concepts are applicable to other languages and technologies as well.

The session closes with a discussion about when and where to write fitness functions and who should write them – and why the use of fitness functions can help bridge the gap between architects and software developers.
