Fitness Functions to Ensure Architectural Goals Are Met

With fitness function-driven development it is possible to write tests that measure a system’s alignment with architectural goals, similarly to how we use test-driven development (TDD) to verify that features conform to desired business outcome, Paula Paul and Rosemary Wang write in a blog post, describing the basic ideas of fitness functions and how architecture qualities can be verified.
