Protect your invariants — A practical TDD session | Oresztesz Margaritisz | EN

How do you handle constraints and validation inside your application? Most of the developers still tend to think around model-view-controller and put this logic somewhere close to their application's boundary. Actually, this prevents them from having a rich domain model and ensuring consistency. In this hands-on TDD session we will go through a practical task and implement it step-by-step. We're going to divide the problem into smaller pieces and solve them individually, then put together a working solution with object composition. I'll show why putting constraints and validation inside your domain is effective and how you can apply these invariants into an aggregate.
