Factories are a powerful tool for decoupling construction logic from our business logic. The Factory Method pattern not only helps by moving creation responsibility to the Aggregate Root, but it could also force Domain invariants. Using the Abstract Factory pattern in our Services allows us to separate our Domain logic from Infrastructure creation details. A common use case is that of Specifications and their respective persistence implementations. We've seen that Factories come in handy on our test suites too. While we could extract building logic into Object Mother Factories, Test Data Builders provide more flexibility for our tests.

Overview of this book
Domain-Driven Design (DDD) has arrived in the PHP community, but for all the talk, there is very little real code. Without being in a training session and with no PHP real examples, learning DDD can be challenging. This book changes all that. It details how to implement tactical DDD patterns and gives full examples of topics such as integrating Bounded Contexts with REST, and DDD messaging strategies. In this book, the authors show you, with tons of details and examples, how to properly design Entities, Value Objects, Services, Domain Events, Aggregates, Factories, Repositories, Services, and Application Services with PHP. They show how to apply Hexagonal Architecture within your application whether you use an open source framework or your own.
