Functional and Reactive Domain Modeling

Chapter 9. Testing your domain model

This chapter covers

• Designing testable domain models
• Learning why xUnit-based testing isn’t enough
• Introducing property-based testing
• Using properties as executable blueprints for domain behaviors

This chapter covers testing your domain model. I begin with an explanation of what is meant by a testable model and how testability is related to the modularity of a model architecture. I take examples from some of the model components discussed in earlier chapters and look at how to test them. Then I discuss briefly the shortcomings of xUnit-based testing and dive into the details of property-based testing using ScalaCheck.
